@jackthegamer I'm in the process of building a computer for a blind friend. He has no use for pretty lights, but with the money he had available (spent just over $1k), I ended up having to buy some of the parts having LEDs. Now, if only I can find the power supply I'm giving him...it doesn't have LEDs.
I love how you blend comedy in with your explanations of things, but don't get off track. Makes the video very easy to watch, funny, and an overall enjoyable experiance. Thank you so much!
You probably wont see this but please do this more often! I am planning my first ever build and I am currently watching all of your tutorial and build videos. Going into detail really helps me build up the confidence to actually do this myself and not spending my lifesavings on getting a prebuild which would probably be weaker :,) Thanks for all your advice and stuff
It'll take me at least a year before I can start to build my first PC, but I'm already checking out videos like this to be as informed as possible about every important detail. Great video, thanks!
i get your "pour some sugar on me 80's joke" Jay. Time flies by quickly, that's for sure. Thank you for the info on the positioning of the power supply. Answers a lot of questions.
I'm not trying to be difficult or contradictory, but I for one would love to see some scientific testing done, over time, to verify these statements. I see a lot of videos about positive vs. negative pressure. I don't know what to believe and would love some actual proof. JayzTwoCents seems like the type to do the test and report back whether he was correct or not. Its why I watch, unwavering integrity.
What scientific proof do you need? If you draw more air in than you remove, the air will go out through the crevices of the case, thus resulting in less dust accumulating. You don't need "scientific testing" to verify common sense.
Without proof all you have is theory. Have you measured the amount of dust present in a case with positive pressure vs a case with negative pressure? If not, how can you be sure one is better than the other. Also, last I checked you are not Jay. So my comment was not directed at you.
James Rhodes I doubt there are many who would bother with that because a) it's something that is intuitive to most people, and b) experience confirms it but hey, good luck on finding those test results!
RIGHT ON JAY! Some of us are not pros and are new to PC builds. And many (apparently) are PC geniuses that can tell you how every part you've ever bought is the wrong one.
OMG, some of the Reddit comments I've read...wow. Like, some of us are building a PC for the first time and don't know everything about everything...which doesn't automatically make us morons.
@@Sampson2012bot That is true. Not knowing everything about everything when building a PC for the first time is not what made you a moron. (there are other factors at play)
Mine is about 75 max unless the ambient outside is warmer than usual like peak summer, out of games 35 max, although I'm not running much from 2018-present
@Orion 8096758 if you have the right case fans the inside of you pc will not be warm. mine is generally about the same as the outside room temperature. (two front fans as intake, two top fans and a rear as exhaust)
@Orion 8096758 He actually did address that with the entire circulation conversation when he started talking about the fan being faced down, he just didn't word it as such.
I'd be interested in finding out just how much of that PSU exhaust loops back into the intake in the down configuration, as you suggested. I think the chassis exhaust fan above it should help keep that air on an aft trajectory. Plus, exhaust tends to be more directional than intake.
I think it's simple. Having the cooler upwards, means pulling warm air into the psu. Probably the temperature inside the case decreases, but the PSU cooler is not for cooling the inside of the pc. It needs fresh air and it can get fresh air only from the downside. That's why mostly every case has an opening for the psu cooler at the bottom. Now tell me I'm wrong?
Hey Jay, I just had to say that I stumbled upon your channel a few months ago during my research trying to learn about gaming on computers and what i would need/want in my first gaming computer build. Thank you for having a huge selection of videos to watch that was able to explain complex ideas in a simple manner to a person who had zero experience in computer building or even how a computer functions. As I now find myself semi competent at the most basic level, I still enjoy watching any of the videos you create to stay present on any new hardware or how to benefit the hardware. Thank you Jay for being awesome!
@Bruce Wayne "common sense"? You seem to lack any. The guy asked a reasonable question and Jay provided no proof to his claims. The only thing you seem to be able to do well is swear and show the world that you are a moron.
Mounted the PSU up. Just got a new M2 NVME which I tried to install. Dropped the M2 screw down in the PSU. Didn't want to open the PSU. But the screw got stuck inside the PSU. Took forever to get it out. Had to unscrew the PSU and flip it upside down and shake it for a long time. I remounted the PSU down now. And will do it going forward.
Lay PC down if you doing work. I have 3x A12x25s at front. Air only in via filtered front. Air out via rear fan, GPU vent and PSU. Every other hole, no matter how small taped up, even PCI slot cover holes. PSU fan is hybrid and never needs to come on. The positive pressure from front fans is huge and is almost enough to blow lighter flame out if placed near psu vent. Front fans dialed in with noctua fan controller. Highest speed without being audible in dead of night. GPU is always 'actively' cooled via the flow too. Clean case, silent, cool.
Jay is the only person I’m cool with belittling me lol this is probs my fav beginners guide type channel since the more I understand certain things you have videos about more intricate things it’s nice to know people can actually learn from your videos
As long as you can put a dust filter on the fan itself, then yeah, I'm with you. Just be careful doing any maintenance with the tower standing, because screws can fall into your PSU and it's a pain in the butt to get out. XD
How about what gigabyte fucked up in the 10th series g1 gaming cards? I know for sure that 1070 has a fan issues like mine rx 480 which results in 1 fan sounding like rotor when first starting,also the insane temps on the rx 480 even after the bios update.I really wish I could make something about that cuz that card can't even hold the advertised clock on the box,it's always going up and down but never stable even on 72-3 C
Hi Jay, basic subject I've been meaning to suggest - what kind of temperatures we should be seeing inside of a water cooling loop - when we have a single pump and res config for say - 1 CPU and 2 GPUs (1080 GTX?). What would be the ones we'd expect coming out of the rads, after it comes out of the GPU blocks, CPU block, etc. An overall overview of water temps in the system.
If we put the unlikely posibility of a pressure issue(dust entering without passing filter) aside, your system overall will likely benefit from this way of mounting the PSU. Here is why; If the fan facing down is the normal way, then the electronics that produce heat inside the PSU will be mounted on the side facing up into the cabinet. The heat will then travel up, away from the fan, potentially get trapped between the electronics and the metal plate and heat it up. By mounting it with the fan facing up, the heat will travel up towards the fan and heat said metal plate less, in addition the previously warmer plate now face outwards against the cool air under the cabinet. All in all I don't think it will make a noticeable difference and either way of mounting it is fine. Exception for the water cooled systems.
Nice video. Great explanation and advice. One thing I do not agree with. It's almost impossible to have a loop of suction air from the power supply if it's mounted with the fan downwards. It is advicable to have the intake air fans at the bottom or in the front of the PC, because the warm air is lighter than the cold air. That's why they changed the position of the power supply as we remember years ago it was at the top. If you mount the power supply with the fan downwards(not on carpet) it will always suck a cold air, because it's heavier and it stays at the bottom. The warm air that goes out from the power supply wil immidiately go up so it's impossible to be sucked in again unless you have a intake fan on the back top case . Mounting the power supply upwards it's not a bad thing too if you have a infront intake fans. But having a powerful GPU might cause a slight problem since the power supply will always suck it's not so much cold air. It actually all depends if you want to use your powwer supply as a exhaust fan too or keep the supply in a good condition.
I've had a couple of power supplies die prematurely from being fan side down. All Corsair models. My theory is that the "smart" fan on Corsair PSUs won't turn on unless your computer is drawing a certain power level. Even if the power supply gets dangerously hot the fan won't kick on. The temperature safety limit will always be hit before the fan is turned on. When flipped fan side up, natural convection is enough to solve the problem entirely.
I agree with everything. Unfortunately, I have a little compartment where the PSU goes on the bottom of the case. Pointing it upwards would probably constrict the air flow even worse.
Great topic. I have my EVGA Supernova 850w mounted down, because the case is on a solid surface, and there's a cover over it. I would recommend making sure you don't forget to check the bottom filter when you are cleaning your case. It is easy to forget about it. Mine needs regular cleaning, almost more than the internals.
Yeah because 240v comes through the CPU, GPU or memory lol.. less than 2v goes through those and you wont even feel that. Meanwhile the PSU is full of capacitors that, if blown, will release a deadly shock.
Holy shit! Jay is getting bigger and bigger (not your weight lol). This channel is growing so fast! The amount of likes, subscribers, and views have grown so much! May not say much for what you're actually earinng but nevertheless, that's awesome! As fans we should be proud!
I recently bought a new case and put my power supply in fan up. I have an extremely dusty environment and carpet (that hasn't been vaccuumed in 15 years). Good to know that newer power supplies don't spin their fans that much. I have two intake fans at the front, that are slightly stronger than two exhaust fans one on top and one at the rear. All are running by Smart fan 5 on my motherboard so balance themselves out automatically.
Noise is a factor too, esp. in a very quiet system. Having the fan inside the case, it has no noise direct escape path. Even if it has to work a bit harder, it is quieter. Also the fans are more effective blowing down than blowing up (where the gravity and the push work against the seal holding the blades)
You realize that fans in a computer case are for cooling. Warm air rises. Why would fans be more effective blowing down? (this is not an actual question and is very sarcastic)
@@paulmartin2348 There are new fans that blow in the opposite direction so they work OK blowing up. But the mechanics of the fans are such that it is much more effective (and thus quieter) when blowing down, against the gravity. If the fan blows up, it is resting on the O-ring that holds the spindle. Plus the air pressure. The convection is not a factor in a case, there is far too much of air movement inside. The fans can easily overmatch the convection.
I've always wondered why more water coolers don't use non conductive liquids, like the XSPC XS-EC6-CL Non Conductive Coolant. Is it less efficent than distilled water? I think a test is in order Jay. Whilst you are at it, what actually happens if this stuff spills on your motherboard, or your PSU?
No no no, you are an expert user, I am an advanced user. I've watched a few of your videos over time and your expert views help sway my builds. Keep it up, subbed.
Thanks for this video. I am building a budget rig around a 6600K and bought an old C70 case secondhand, which I freaking love the look of. I was installing the PSU (EVGA 650 GA, also secondhand) last night and having this debate internally. I settled on fan up orientation for now but may give it further consideration.
I tried both configurations, i wanted to see if the psu up inlet would improve air flow and draw more hot air away from the gpu, yes it would heat up the psu and have a de rating affect but the psu is oversized so this wouldn't be an issue. The result was the exact same gpu temp in both configurations which was surprising since you would think this would assist the gpu exhaust. So i left is in the down inlet standard config.
@@Ethan-rz6cx You are correct intake side on top with heat exhaust going out the back of the unit. In my recent build I had no choice but to place the intake down because of separate enclosure for power supply draws air from below. Without the enclosure I would have gone intake facing up, just to draw heat from inside the box out.
When the PSU is sucking air in from below and letting it push itself out the back, there is still a suction pressure from beneath that will make even the hot air go down. You are correct that hot air rises in cold air, however, the rate at which this happens is far slower than you may expect, especially when we are talking only a few degrees difference.
Today i removed my corsair HX1050 i installed upside down on my 9 year old rig.. the backside of the power supply has like a thick layer of dust, i couldn't even blow it off by air.. then i was surprised when i examined the internal components of this power supply through fan vents! it looked so clean from dust as if it is unpackaged from it's retail box!!. am now 100% convinced that i would never place my power supply facing up ( as long as on solid floor).. the power supply fans would only rotate when it needs to cool, so on normal usage it is mostly off.. so having power supply vents toward inside case will only collect dust from moving air inside.. not only that.. but if a lot of dust accumulated inside power supply it may reduce cooling efficiency meaning fans will spin more often years later.. the face down approach have more benefits on the unit it self compared of pulling some air from case.. you can add regural case fans instead..
Heh, sorry for bumping the thread. Just rearranged my cases and couldn't understand why all pc components raised 5-15 degrees Celcius. Reason for switching my main hardware system to my newer, cheap Riotoro CR 488 was that it was almost 'empty' inside with room for tons of additional case fan mounts - where my old Cooltek midi case included tons of hdd shelves, filling the inside up, blocking airflow, not suitable for my newly ordered huge GFX card. Then realized my old cheap German CoolTek midi case had the PSU mount upside down. And having a big solid hightadjustable table there is plenty of free air beneath the case suspension the answer was obvious. So now my PSU is installed 'mountless loose' in my Riotoro CR 488 upside down - and what a temps difference to the good side!
Wow! This is perfect! I have a carpet but don't have much room to put it anywhere. My first power supply burned out due to dirt and dust intake from the bottom cent, because I didn't realize it sucked in at the time, so this would help with that. After the first one burnt out, I managed to squeeze a table in, but now that I know this I might think about doing this!
Vaughn Armstrong lol honestly it worked my PSU is still sitting with the fan facing up since this post and dust hasn't caused any sort of issue temps never changed inside of the pc I tried flipping the case but I couldnt reach the USB ports like that so test was inconclusive.
I’m building a Sleeper PC with a top mounted PSU and a single 92mm rear exhaust fan. I have the PSU mounted with the 120mm fan facing down to act an extra exhaust fan. Works flawlessly!
Hey Jay. Could you please do a video about PCI-E Overclocking with a couple of facts, benchmarks and risks? Theres pretty much no information on the internet about that topic and id like to know if you can gain performance from that. Best regards
I actually built my rig yesterday with NZXT h500 and have to stop for about 10mins to decide how I mount it and ended intake fan face down because: 1. I want to take it cool air into the power supply,; 2. because I already have positive air pressure by installing additional 2 140mm front panel fans... but hey this is a good video. kudos!
Thanks for this video. While I have been around PCs since the dawn of time (Tandy TRS-80, Commodore PET, Apple II), and I have built a few PCs in my time, I have never seen anything about mounting a power supply with the fan down before. Given that all of the printing on the exterior of my power supply’s would only be upright wi the the fan up, I thought that was the only way to mount it. My current case has the grate on the bottom so I mounted my PSU “upside down” and at least I know that it won’t hurt anything.
Just a warning.. I mounted mine with the fan faced up since my PC sits on a carpet, and while mounting the backplate of an AIO cooler, a washer fell into the crevice between the motherboard and case, then landed in the power supply. I didn't realize this until it was too late. After testing my PC for a bit it was fine. I brought it upstairs to my normal spot, flicked the switch then hit the power button, and was then greeted with a nice gunshot sound paired with a white flash as soon as I hit the power button... Though it was my own stupidity in running the PSU without finding the missing washer... I'm never mounting my PSU with the fan faced up again. I ran into this video shortly after it happened so I don't know if the components are okay yet. :/
Sirei Talk Ouch.. Any update now? How did it hold up? Watercooling is still a constant gamble it seems, I’m always paranoid about it, considering I got myself an AIO for the first time Fans facing down from now on 100%
@@computethis7128 Mine hasn't leaked, so I can't really say whether it's worth it or not.. But so far it seems worth it for how beautiful it looks and for how well it performs. There really isn't any maintainence to be done since the liquid inside is never exposed to anything.. though I don't know for certain if it would ever need to be done.
Since my 600C forces me to use my PSU as an exhaust fan I am really happy with this solution. This was I only have three fans inside my case (including the PSU) and the system is a lot quieter.
There are several issues with your presumptions about case airflow here Jayz - 1) it doesn't matter if you're using +ve or -ve case pressure, the ingress of dust is exactly the same. You also said you like to use neutral pressure in your case - this is impossible if there are ANY fans in use - you cannot have neutral pressure inside the case when case fans are in use. 2) As for PSU orientation - as you say, many higher wattage PSU fans do not come on until the current (wattage) draw is at a certain point, or when the PSU reaches a set internal temperature, so I mount my PSU with the air input upwards as, when the fan is not spinning, which it never does on my Corsair HX1000i PS, then what ever heat it is producing, my PSU runs at about 35°c, goes up, as heat rises, out into the case.
They should really be mounted at the top of the case like they used to be, which was for a design factor reason. Regardless of the fans intake / out take of the PSU heat 'radiates' from it (PSU one of the hottest parts of the PC). & where does that radiated heat go? Straight up or straight over all the components you want to keep as cool as possible, from bottom to top (some gets vented by fans, some of the hot air gets fed to cool heatsinks though too, which doesn't do as good a job. It (bottom mounting) started to appear when water cooling came on the scene & holes for the hoses appeared at the top of the case along with the dilemma of where the radiator / reservoir & all that jazz would sit (at the top, at least in the early days). I guess they figured if components were all on a water cooled loop the extra radiated heat wouldn't matter none. But for an air cooled system, it is extra heat in the case whether we like it or not.
Some comments from the top of my head: - When the power-supply fan is not spinning then it is not contributing to air-flow. The video mentions both, but does not link one argument to the other. Having an open grill pointing upwards then allows for the PSUs heat to spread even easier inside the case. - A down-facing fan can suck dust into the PSU when no filter is installed. An up-facing fan will suck dust into the PSU from within the case. Even if the fan is not running, dust will fall through the open grill, because there is no filter on top of it. Regular mesh on PC cases does not filter dust. Check the dust in your case and decide if this is a possible problem. - It seems rather unlikely that the PSU will suck warm air from its exhaust back into a down-facing fan. The heat is exhausted at pressure and then travels upwards. The down-facing fan pulls air from all directions if unblocked, air temperature below the case should usually be coolest, especially with the case standing on the floor. - Pulling air from within the case likely is going to be warmer once a graphic-card is installed that pushes its hot air back into the case (as most cards do). This means the PSU gets hotter rather than cooler, which is ok, because a PSU usually is meant to operate at up to 50°C ambient temperature and then contribute to case ventilation. If the fan is even spinning that is.
The PSU may suck its exhaust air back in if the PC is close enough to a wall. The exhaust air out the back will hit the wall and scatter in all directions, including down to where the intake will suck it back in. I doubt the small amount of warmer air would have much of an effect on the overall temp of the PSU. The amount of warm air as well as all the cool air would make the intake temp effectively ambient anyway.
I've moved from an air 240 to a 570x case. (yeah i know, it's big for a MATX board). However with the Air240, my PSU died. You have to mount that facing out. I suspect vaping mind have contributed to that. I've since switched some stuff around in my room too and bought a fan (an actual fan) so the vapour doesnt have a chance to settle, and yes, mounted my new PSU facing up so its drawing it's air from inside the case.
My old case has no bottom vent. My only problem has been dropping a screw in the power supply. Be sure to cover the top of the supply when working in the case.
Dang, nice PDXLAN shirt! I attended twice when I was in high school, probably around 2005 or so. It was the first time I went to a LAN party bigger than my friend's basement. What an experience!
I had carpet when I lived in an apartment for college. I bought some whiteboard wood and had it cut at home depot for roughly 10$. Placed this under my PC to provide some space for air flow and also had left over whiteboard to mount on my wall for "normal" whiteboard uses.
Allow me to summarize without watching the video. Down: You have good airflow under the case. Not sitting on carpet suffocating the fan. Or you dont trust your water cooling setup. 🤣 Up: Down isnt an option due to airflow.
No, he mentioned it depends on where you're planning on putting your tower, if you put it on a carpet floor with no case feet, fan facing up is ideal unless you want to blow up your PSU. And a few more things. edit - posted that comment before Jay mentioned carpet.
It doesn't make any SIGNIFICANT difference. Though if you're building you might as well mount it accordingly and optimize since it's not hurting you or your time. If you're putting it on carpet, face the fan upwards. If on hard surfaces, face it downwards to help keep dust out. And Jay made a good point I didn't think of, watercooling and potential leaking into the fan could cause a potentially, VERY bad day. But in the end it's not a big deal. Kinda like how people freak out over not having anti-static mats/wrist bands, people go their whole lives without static discharge frying their equipment but it's a nice practice if you don't want to take any chances.
Well yeah, the static discharge is a bit of a scare, but so are many other things like smokers falling asleep with a burning cigarette and getting set on fire. Maybe not the best reference, but the chance of that are very slim, yet it could happen and if it happen the consequences might be serious. I started wearing the wrist straps just to be sure, tho following basic guidelines like evading wearing too much and specifically e-static prone clothes like wool sweaters and shit. Not saying to build half naked or fully naked, tho that might be a really fun idea if you're building with your gf, tho the build might turn slower than expected then, but hey savor more moments. :P And again, sjw's and feminazi would be triggered so that would be "sexhist"... -_- Which is only another reason to do it. :D With your bf/gf's consent of course. Which is pretty much inherently self explicit, hence we don't really live in a rape culture. But I digress. xD Pretty much you can decide about your PSU given your environment. I personally would rather install it the normal way and not have dust fest fluffy carpet, especially if you're allergic to domestic dust [acars/mites]. Or you can simply put a nice platform there, but srsly, those carpets aren't really that good in general if you're gonna leave your pc on the ground. You will still get more dust compared to a flad surface, unless you don't mind and can vacuum it more often than the other stuff.
Basically, I think what PSU you are buying is much more important than what way you will put the fans. Also, although it's better to get a "bigger" psu in terms of power, [you'll also shouldn't buy bigger but crappier psus], with processors [cpu + gpu] getting ever more efficient, you don't need like +1000w powerhouses. You can easily get away with anything from [400W if very good, 450W if decently] like 500w - 850W, for the average [gaming] user, I would say anywhere around these estimates, depending on what you want to do with it. More particularly running multiple gpus. I generally prefer the strongest single gpu than bothering with sli/xfire. As for the newer api way, which I think is much better idea, tho I don't think I will be doing this any time soon neither, and my reason would probably be if I could/want to run two cards and get benefits from exclusive features, without having to have a separate system to benefit from them. And/or you could bring some enhancement in performance without any harmful disadvantages. But that being said, you are better buying a tougher more quality PSU, than going for the sole higher wattage. It's a good idea to go higher than "needed", as long as you don't need to drop the efficiency rating. Sorta like a thumb rule. Better get a quality 650W Gold [some like the SeaSonic and CoolerMaster are gold, but nearing Platinum] than going for a 750W Silver / cheaper quality. But honestly, that's just my preferences and these days, unless you are buying some really trashy PSU from some weird brand you will not have regrets. :P
Great video/topic Jay. I've built many PCs and I've always wondered what the preferred method was to mounting the power supply. You made me aware of things I hadn't thought of. Thanks!
this is a good idea to know. never would think about which ways to mount a psu. i had always mounted psu down and not up cause it was never a gaming pc. the gaming case ps i have i just learned something about which is a better way to mount the psu. so i did mount up to give inside my case a better air flow. thank you for this video. always learn something new know matter how old you are.
My take away, you just got a second fan (myself) pushing old air out meaning more fresh in. I almost set it fan down because the print would be right side up outside of tower where it would be plugged in. Well that's a DUMB reason to mount it if the fan mounted up inside and there's plenty of free space for the fan on the power supply to draw air out of the tower. Remembering that getting fresh (and cooler) air into the tower is just as important as exhausting the warmer (and older) air. Well, least he gave good reasons to mount it upside down? Yes he did. Thanks! And now I know the reasoning behind it too! And that's half the battle, understanding WHY you set the system up as you do it instead of using your solid but flawed logic because there are just some things you personally don't understand that can and will bite you in the butt later. This suggestion is a minor one but get enough minor ones and it turns major eventually.
Hey, Jay! Remember top-mounted power supplies? No shrouds, sometimes the only exhaust fan in the system? Couldn't flip them if you wanted because the screws wouldn't go in that way? Cable management meant stuffing them into the unused 5.25 bay that didn't have an optical drive in it? Good times. I am feeling so old now.
That was happening to me with my built. The hot air from the case was f*** up all my PSU until one day I decide to flip it down and from then on never encountered air flow problems with the PSU.
Yes ,that's why psu manufacturers always recommend fan down, it's nearly always better to intake fresh,filtered air for PSU ,CPU and GPU and let case fans exhaust hot air from case, positive pressure also helps as it forces hot air out of the case as well as reducing dust.
@@andrewdupuis1151 A perfect power supply would only use the amount of power it needs to provide. Real power supplies are generally more efficient when you use more than 50% of the power they can supply.
If the PSU fan comes on, that means the PSU is running hot and needs air flow to cool down. Ideally, you don't want to be venting hot air inside the case through the PSU to cool the PSU down. Mounting the PSU fan downwards is the best option for keeping the PSU cool so long as the other safeguards mentioned are met (like no high rise carpeting and an airgap between case bottom and floor) and so long as there are at least a few vents in the top of the PSU enclosure allowing the hot air to escape and be sucked out of the PC case through the case's upper exhaust fan when the PSU fan isn't spinning. The air loop scenario mentioned is only a problem if the computer case is land-locked inside a cabinet, otherwise the hot air is projected outward and upward from the rear, which actually helps to suck cooler ambient air from the front of the case up through the bottom vent.
If the power supply is mounted with the fan up, and the graphics card has an open air cooler, they would both be fighting for the same air, especially if they are close to each other. Just a taught. Great video by the way.

I am planning my first ever build and I am currently watching all of your tutorial and build videos.
Going into detail really helps me build up the confidence to actually do this myself
and not spending my lifesavings on getting a prebuild which would probably be weaker :,)
Thanks for all your advice and stuff
Exactly the same!! On my next Pc ima build one and all these videos are very VERY!! helpful 😅
It'll take me at least a year before I can start to build my first PC, but I'm already checking out videos like this to be as informed as possible about every important detail. Great video, thanks!
Well?
Did u build it?
Pc update?
i get your "pour some sugar on me 80's joke" Jay. Time flies by quickly, that's for sure. Thank you for the info on the positioning of the power supply. Answers a lot of questions.
TLDR:
Fan down: with power supply shroud, or water cooling
Fan up: on carpet, one exhaust fan, most setups
water cooling......
@@EmomanTavish gas warming......
Thanks. Saved me a whole 7 minutes and 36 seconds.
Sick Corsair SF750 badge to display: fan down.
TLDW no one reads videos
I'm not trying to be difficult or contradictory, but I for one would love to see some scientific testing done, over time, to verify these statements. I see a lot of videos about positive vs. negative pressure. I don't know what to believe and would love some actual proof. JayzTwoCents seems like the type to do the test and report back whether he was correct or not. Its why I watch, unwavering integrity.
What scientific proof do you need? If you draw more air in than you remove, the air will go out through the crevices of the case, thus resulting in less dust accumulating. You don't need "scientific testing" to verify common sense.
Without proof all you have is theory. Have you measured the amount of dust present in a case with positive pressure vs a case with negative pressure? If not, how can you be sure one is better than the other. Also, last I checked you are not Jay. So my comment was not directed at you.
+James Rhodes I've already does this test about air pressure with smoke
James Rhodes
I doubt there are many who would bother with that because a) it's something that is intuitive to most people, and b) experience confirms it but hey, good luck on finding those test results!
Do you have a video up? If so I missed it. I would like to see it. If not, maybe you could do one. I think it would be interesting to see.
RIGHT ON JAY! Some of us are not pros and are new to PC builds. And many (apparently) are PC geniuses that can tell you how every part you've ever bought is the wrong one.
Gilbert Quintanar well duh because everything you know is wrong and jay cant be right cuz the internet is never right
OMG, some of the Reddit comments I've read...wow. Like, some of us are building a PC for the first time and don't know everything about everything...which doesn't automatically make us morons.
@@Sampson2012bot That is true. Not knowing everything about everything when building a PC for the first time is not what made you a moron. (there are other factors at play)
My Gpu runs around 80C at full load, I don't think the psu will be pulling any "cool" air from it.
Mine is about 75 max unless the ambient outside is warmer than usual like peak summer, out of games 35 max, although I'm not running much from 2018-present
@Orion 8096758 if you have the right case fans the inside of you pc will not be warm. mine is generally about the same as the outside room temperature. (two front fans as intake, two top fans and a rear as exhaust)
and i know this as a fact as there's a temperature sensor inside
@Orion 8096758 He actually did address that with the entire circulation conversation when he started talking about the fan being faced down, he just didn't word it as such.
47 max here, though is that normal with older hardware?
I'd be interested in finding out just how much of that PSU exhaust loops back into the intake in the down configuration, as you suggested. I think the chassis exhaust fan above it should help keep that air on an aft trajectory. Plus, exhaust tends to be more directional than intake.
I think it's simple. Having the cooler upwards, means pulling warm air into the psu. Probably the temperature inside the case decreases, but the PSU cooler is not for cooling the inside of the pc. It needs fresh air and it can get fresh air only from the downside. That's why mostly every case has an opening for the psu cooler at the bottom. Now tell me I'm wrong?
Hey Jay, I just had to say that I stumbled upon your channel a few months ago during my research trying to learn about gaming on computers and what i would need/want in my first gaming computer build. Thank you for having a huge selection of videos to watch that was able to explain complex ideas in a simple manner to a person who had zero experience in computer building or even how a computer functions. As I now find myself semi competent at the most basic level, I still enjoy watching any of the videos you create to stay present on any new hardware or how to benefit the hardware. Thank you Jay for being awesome!

Mounted the PSU up. Just got a new M2 NVME which I tried to install. Dropped the M2 screw down in the PSU. Didn't want to open the PSU. But the screw got stuck inside the PSU. Took forever to get it out. Had to unscrew the PSU and flip it upside down and shake it for a long time.
I remounted the PSU down now. And will do it going forward.
Lay PC down if you doing work. I have 3x A12x25s at front. Air only in via filtered front. Air out via rear fan, GPU vent and PSU. Every other hole, no matter how small taped up, even PCI slot cover holes. PSU fan is hybrid and never needs to come on. The positive pressure from front fans is huge and is almost enough to blow lighter flame out if placed near psu vent. Front fans dialed in with noctua fan controller. Highest speed without being audible in dead of night. GPU is always 'actively' cooled via the flow too. Clean case, silent, cool.
Lucky it was just a screw, if the P/S was the right way up passive air flow would do the work, cooler air falling as warm rises ...
Same happened to me. That's why I'm watching this video 🤣🤣🤣
I am right now building my first computer and several of your videos have been so valuable!
Jay is the only person I’m cool with belittling me lol this is probs my fav beginners guide type channel since the more I understand certain things you have videos about more intricate things it’s nice to know people can actually learn from your videos
As long as you can put a dust filter on the fan itself, then yeah, I'm with you. Just be careful doing any maintenance with the tower standing, because screws can fall into your PSU and it's a pain in the butt to get out. XD
Thanks for the support guys, means a lot! Don't forget to let me know what other basic subjects you think I should cover!
How about what gigabyte fucked up in the 10th series g1 gaming cards? I know for sure that 1070 has a fan issues like mine rx 480 which results in 1 fan sounding like rotor when first starting,also the insane temps on the rx 480 even after the bios update.I really wish I could make something about that cuz that card can't even hold the advertised clock on the box,it's always going up and down but never stable even on 72-3 C
JayzTwoCents
Hi Jay, basic subject I've been meaning to suggest - what kind of temperatures we should be seeing inside of a water cooling loop - when we have a single pump and res config for say - 1 CPU and 2 GPUs (1080 GTX?).
What would be the ones we'd expect coming out of the rads, after it comes out of the GPU blocks, CPU block, etc. An overall overview of water temps in the system.
That Def Leppard reference :D
If we put the unlikely posibility of a pressure issue(dust entering without passing filter) aside, your system overall will likely benefit from this way of mounting the PSU. Here is why;
If the fan facing down is the normal way, then the electronics that produce heat inside the PSU will be mounted on the side facing up into the cabinet. The heat will then travel up, away from the fan, potentially get trapped between the electronics and the metal plate and heat it up. By mounting it with the fan facing up, the heat will travel up towards the fan and heat said metal plate less, in addition the previously warmer plate now face outwards against the cool air under the cabinet.
All in all I don't think it will make a noticeable difference and either way of mounting it is fine. Exception for the water cooled systems.
I'm planning on building a pc and I'm gathering all the knowledge I can. thanks for the tips jay!

I'm not 30 yet and I got it, Def Leppard is awesome.
Very helpful dude. I have installed fan down all the time. This gives me an argument for upward.
Nice video. Great explanation and advice.
One thing I do not agree with.
It's almost impossible to have a loop of suction air from the power supply if it's mounted with the fan downwards.
It is advicable to have the intake air fans at the bottom or in the front of the PC, because the warm air is lighter than the cold air. That's why they changed the position of the power supply as we remember years ago it was at the top.
If you mount the power supply with the fan downwards(not on carpet) it will always suck a cold air, because it's heavier and it stays at the bottom. The warm air that goes out from the power supply wil immidiately go up so it's impossible to be sucked in again unless you have a intake fan on the back top case .
Mounting the power supply upwards it's not a bad thing too if you have a infront intake fans. But having a powerful GPU might cause a slight problem since the power supply will always suck it's not so much cold air.
It actually all depends if you want to use your powwer supply as a exhaust fan too or keep the supply in a good condition.
"Endless supply of content topics" No pun intended
A powerful statement
I felt alot of energy in this comment
We're supposed to mount the power supply, i usually just let it hang at the top of my case
I've had a couple of power supplies die prematurely from being fan side down. All Corsair models.
My theory is that the "smart" fan on Corsair PSUs won't turn on unless your computer is drawing a certain power level. Even if the power supply gets dangerously hot the fan won't kick on. The temperature safety limit will always be hit before the fan is turned on.
When flipped fan side up, natural convection is enough to solve the problem entirely.
I agree with everything. Unfortunately, I have a little compartment where the PSU goes on the bottom of the case. Pointing it upwards would probably constrict the air flow even worse.
Great topic. I have my EVGA Supernova 850w mounted down, because the case is on a solid surface, and there's a cover over it. I would recommend making sure you don't forget to check the bottom filter when you are cleaning your case. It is easy to forget about it. Mine needs regular cleaning, almost more than the internals.
This is a positive comment.
These jokes blow me away.
Fuck you.
(that was supposed to be a negative reply :D )
CaveManta It was an airflow pun. Cause the air flow blows. Even if it is neutral.

Holy shit! Jay is getting bigger and bigger (not your weight lol). This channel is growing so fast! The amount of likes, subscribers, and views have grown so much! May not say much for what you're actually earinng but nevertheless, that's awesome! As fans we should be proud!
I recently bought a new case and put my power supply in fan up. I have an extremely dusty environment and carpet (that hasn't been vaccuumed in 15 years). Good to know that newer power supplies don't spin their fans that much. I have two intake fans at the front, that are slightly stronger than two exhaust fans one on top and one at the rear. All are running by Smart fan 5 on my motherboard so balance themselves out automatically.
You should do a video about the basics involving the CPU, PCIE slot numbers, PCIE 1, 2 & 3.0, and how your GPU, CPU and PCIE slots all work together.
Hey Jay!, i've been planning on building a PC for months!, I just want to say thanks for all the the great helpful Vids! :D
Did ya build one?
@@backutZR lol
Noise is a factor too, esp. in a very quiet system. Having the fan inside the case, it has no noise direct escape path. Even if it has to work a bit harder, it is quieter. Also the fans are more effective blowing down than blowing up (where the gravity and the push work against the seal holding the blades)
You realize that fans in a computer case are for cooling. Warm air rises. Why would fans be more effective blowing down? (this is not an actual question and is very sarcastic)
@@paulmartin2348 There are new fans that blow in the opposite direction so they work OK blowing up. But the mechanics of the fans are such that it is much more effective (and thus quieter) when blowing down, against the gravity. If the fan blows up, it is resting on the O-ring that holds the spindle. Plus the air pressure.
The convection is not a factor in a case, there is far too much of air movement inside. The fans can easily overmatch the convection.
I've always wondered why more water coolers don't use non conductive liquids, like the XSPC XS-EC6-CL Non Conductive Coolant. Is it less efficent than distilled water? I think a test is in order Jay. Whilst you are at it, what actually happens if this stuff spills on your motherboard, or your PSU?
Thanks for the video. For myself, I always mount it with the fan facing down simply so that the power supply is protected from potential water leaks.
No no no, you are an expert user, I am an advanced user. I've watched a few of your videos over time and your expert views help sway my builds. Keep it up, subbed.
Thanks for this video. I am building a budget rig around a 6600K and bought an old C70 case secondhand, which I freaking love the look of.
I was installing the PSU (EVGA 650 GA, also secondhand) last night and having this debate internally. I settled on fan up orientation for now but may give it further consideration.
I tried both configurations, i wanted to see if the psu up inlet would improve air flow and draw more hot air away from the gpu, yes it would heat up the psu and have a de rating affect but the psu is oversized so this wouldn't be an issue. The result was the exact same gpu temp in both configurations which was surprising since you would think this would assist the gpu exhaust. So i left is in the down inlet standard config.
That is indeed weird.
Although, out of all the fans, I have the hardest time understanding intake/exhaust and airflow of the GPU fans.
How do you get a heating loop when the warm air exhausted from the power supply rises?
Orion 8096758 I mean I’m pretty sure that the fan facing upwards is an input fan and the warm air is pushed out the back (I think)
@@Ethan-rz6cx You are correct intake side on top with heat exhaust going out the back of the unit. In my recent build I had no choice but to place the intake down because of separate enclosure for power supply draws air from below. Without the enclosure I would have gone intake facing up, just to draw heat from inside the box out.
When the PSU is sucking air in from below and letting it push itself out the back, there is still a suction pressure from beneath that will make even the hot air go down. You are correct that hot air rises in cold air, however, the rate at which this happens is far slower than you may expect, especially when we are talking only a few degrees difference.
Today i removed my corsair HX1050 i installed upside down on my 9 year old rig.. the backside of the power supply has like a thick layer of dust, i couldn't even blow it off by air.. then i was surprised when i examined the internal components of this power supply through fan vents! it looked so clean from dust as if it is unpackaged from it's retail box!!.
am now 100% convinced that i would never place my power supply facing up ( as long as on solid floor).. the power supply fans would only rotate when it needs to cool, so on normal usage it is mostly off.. so having power supply vents toward inside case will only collect dust from moving air inside.. not only that.. but if a lot of dust accumulated inside power supply it may reduce cooling efficiency meaning fans will spin more often years later.. the face down approach have more benefits on the unit it self compared of pulling some air from case.. you can add regural case fans instead..
And I just used the foam packaging to keep my case stably raised above the carpet and make it easier to pick up to work on it.

Heh, sorry for bumping the thread. Just rearranged my cases and couldn't understand why all pc components raised 5-15 degrees Celcius.
Reason for switching my main hardware system to my newer, cheap Riotoro CR 488 was that it was almost 'empty' inside with room for tons of additional case fan mounts - where my old Cooltek midi case included tons of hdd shelves, filling the inside up, blocking airflow, not suitable for my newly ordered huge GFX card.
Then realized my old cheap German CoolTek midi case had the PSU mount upside down. And having a big solid hightadjustable table there is plenty of free air beneath the case suspension the answer was obvious. So now my PSU is installed 'mountless loose' in my Riotoro CR 488 upside down - and what a temps difference to the good side!
Wow! This is perfect! I have a carpet but don't have much room to put it anywhere. My first power supply burned out due to dirt and dust intake from the bottom cent, because I didn't realize it sucked in at the time, so this would help with that.
After the first one burnt out, I managed to squeeze a table in, but now that I know this I might think about doing this!
Awesome Video as always!
Thank you Jay ;)

Nice something to watch before going to bed
Mounting upwards also helps the heat (which moves up) escape more easily for semi passive units.
I’m building a Sleeper PC with a top mounted PSU and a single 92mm rear exhaust fan. I have the PSU mounted with the 120mm fan facing down to act an extra exhaust fan. Works flawlessly!

I actually built my rig yesterday with NZXT h500 and have to stop for about 10mins to decide how I mount it and ended intake fan face down because: 1. I want to take it cool air into the power supply,; 2. because I already have positive air pressure by installing additional 2 140mm front panel fans... but hey this is a good video. kudos!
Thanks for this video. While I have been around PCs since the dawn of time (Tandy TRS-80, Commodore PET, Apple II), and I have built a few PCs in my time, I have never seen anything about mounting a power supply with the fan down before. Given that all of the printing on the exterior of my power supply’s would only be upright wi the the fan up, I thought that was the only way to mount it. My current case has the grate on the bottom so I mounted my PSU “upside down” and at least I know that it won’t hurt anything.
Just a warning.. I mounted mine with the fan faced up since my PC sits on a carpet, and while mounting the backplate of an AIO cooler, a washer fell into the crevice between the motherboard and case, then landed in the power supply. I didn't realize this until it was too late. After testing my PC for a bit it was fine. I brought it upstairs to my normal spot, flicked the switch then hit the power button, and was then greeted with a nice gunshot sound paired with a white flash as soon as I hit the power button... Though it was my own stupidity in running the PSU without finding the missing washer... I'm never mounting my PSU with the fan faced up again. I ran into this video shortly after it happened so I don't know if the components are okay yet. :/

Since my 600C forces me to use my PSU as an exhaust fan I am really happy with this solution. This was I only have three fans inside my case (including the PSU) and the system is a lot quieter.
There are several issues with your presumptions about case airflow here Jayz - 1) it doesn't matter if you're using +ve or -ve case pressure, the ingress of dust is exactly the same. You also said you like to use neutral pressure in your case - this is impossible if there are ANY fans in use - you cannot have neutral pressure inside the case when case fans are in use. 2) As for PSU orientation - as you say, many higher wattage PSU fans do not come on until the current (wattage) draw is at a certain point, or when the PSU reaches a set internal temperature, so I mount my PSU with the air input upwards as, when the fan is not spinning, which it never does on my Corsair HX1000i PS, then what ever heat it is producing, my PSU runs at about 35°c, goes up, as heat rises, out into the case.
They should really be mounted at the top of the case like they used to be, which was for a design factor reason. Regardless of the fans intake / out take of the PSU heat 'radiates' from it (PSU one of the hottest parts of the PC). & where does that radiated heat go? Straight up or straight over all the components you want to keep as cool as possible, from bottom to top (some gets vented by fans, some of the hot air gets fed to cool heatsinks though too, which doesn't do as good a job. It (bottom mounting) started to appear when water cooling came on the scene & holes for the hoses appeared at the top of the case along with the dilemma of where the radiator / reservoir & all that jazz would sit (at the top, at least in the early days). I guess they figured if components were all on a water cooled loop the extra radiated heat wouldn't matter none. But for an air cooled system, it is extra heat in the case whether we like it or not.
Are you telling me my dell case is superior to a 200 case?
Ok, now you need to tell us how you balance the fans!
2:18 Holy shit I have the same case and *had* that same EVGA PSU! Just upgraded to a Gigabyte Aorus AP750GM PSU now though.
1200W? It's a 600W PSU....
I had to flip my psu to fix some squeaking issue with my psu fan and I was wondering it was a bad idea but now I am no longer worrying, thanks!
Some comments from the top of my head:
- When the power-supply fan is not spinning then it is not contributing to air-flow. The video mentions both, but does not link one argument to the other. Having an open grill pointing upwards then allows for the PSUs heat to spread even easier inside the case.
- A down-facing fan can suck dust into the PSU when no filter is installed. An up-facing fan will suck dust into the PSU from within the case. Even if the fan is not running, dust will fall through the open grill, because there is no filter on top of it. Regular mesh on PC cases does not filter dust. Check the dust in your case and decide if this is a possible problem.
- It seems rather unlikely that the PSU will suck warm air from its exhaust back into a down-facing fan. The heat is exhausted at pressure and then travels upwards. The down-facing fan pulls air from all directions if unblocked, air temperature below the case should usually be coolest, especially with the case standing on the floor.
- Pulling air from within the case likely is going to be warmer once a graphic-card is installed that pushes its hot air back into the case (as most cards do). This means the PSU gets hotter rather than cooler, which is ok, because a PSU usually is meant to operate at up to 50°C ambient temperature and then contribute to case ventilation. If the fan is even spinning that is.
The PSU may suck its exhaust air back in if the PC is close enough to a wall. The exhaust air out the back will hit the wall and scatter in all directions, including down to where the intake will suck it back in. I doubt the small amount of warmer air would have much of an effect on the overall temp of the PSU. The amount of warm air as well as all the cool air would make the intake temp effectively ambient anyway.
Nice video
"In the name of love!"
these are the real questions in life
I've moved from an air 240 to a 570x case. (yeah i know, it's big for a MATX board). However with the Air240, my PSU died. You have to mount that facing out.
I suspect vaping mind have contributed to that.
I've since switched some stuff around in my room too and bought a fan (an actual fan) so the vapour doesnt have a chance to settle, and yes, mounted my new PSU facing up so its drawing it's air from inside the case.
My old case has no bottom vent. My only problem has been dropping a screw in the power supply. Be sure to cover the top of the supply when working in the case.

...and now it's 2019... Positive pressure is the desired configuration. If you are using liquid cooling, use a case with a shroud...
Dang, nice PDXLAN shirt! I attended twice when I was in high school, probably around 2005 or so. It was the first time I went to a LAN party bigger than my friend's basement. What an experience!
I had carpet when I lived in an apartment for college. I bought some whiteboard wood and had it cut at home depot for roughly 10$. Placed this under my PC to provide some space for air flow and also had left over whiteboard to mount on my wall for "normal" whiteboard uses.
and what if the psu never turns on? like my super flower 80plus gold with its eco mode...
Then you don't have to worry about whether or not it gets ventilation.
Allow me to summarize without watching the video.
Down: You have good airflow under the case. Not sitting on carpet suffocating the fan. Or you dont trust your water cooling setup. 🤣
Up: Down isnt an option due to airflow.
Cooler Master NR600. I should mount down? Using a Fractal Design ION+560
Linus did a video on this before. It makes no difference at all. It comes down to " A E S T H E T I C S"
No, he mentioned it depends on where you're planning on putting your tower, if you put it on a carpet floor with no case feet, fan facing up is ideal unless you want to blow up your PSU. And a few more things.
edit - posted that comment before Jay mentioned carpet.
It doesn't make any SIGNIFICANT difference. Though if you're building you might as well mount it accordingly and optimize since it's not hurting you or your time. If you're putting it on carpet, face the fan upwards. If on hard surfaces, face it downwards to help keep dust out. And Jay made a good point I didn't think of, watercooling and potential leaking into the fan could cause a potentially, VERY bad day. But in the end it's not a big deal. Kinda like how people freak out over not having anti-static mats/wrist bands, people go their whole lives without static discharge frying their equipment but it's a nice practice if you don't want to take any chances.
Well yeah, the static discharge is a bit of a scare, but so are many other things like smokers falling asleep with a burning cigarette and getting set on fire. Maybe not the best reference, but the chance of that are very slim, yet it could happen and if it happen the consequences might be serious.
I started wearing the wrist straps just to be sure, tho following basic guidelines like evading wearing too much and specifically e-static prone clothes like wool sweaters and shit. Not saying to build half naked or fully naked, tho that might be a really fun idea if you're building with your gf, tho the build might turn slower than expected then, but hey savor more moments. :P
And again, sjw's and feminazi would be triggered so that would be "sexhist"... -_-
Which is only another reason to do it. :D
With your bf/gf's consent of course. Which is pretty much inherently self explicit, hence we don't really live in a rape culture. But I digress. xD
Pretty much you can decide about your PSU given your environment.
I personally would rather install it the normal way and not have dust fest fluffy carpet, especially if you're allergic to domestic dust [acars/mites].
Or you can simply put a nice platform there, but srsly, those carpets aren't really that good in general if you're gonna leave your pc on the ground. You will still get more dust compared to a flad surface, unless you don't mind and can vacuum it more often than the other stuff.
Basically, I think what PSU you are buying is much more important than what way you will put the fans.
Also, although it's better to get a "bigger" psu in terms of power, [you'll also shouldn't buy bigger but crappier psus], with processors [cpu + gpu] getting ever more efficient, you don't need like +1000w powerhouses.
You can easily get away with anything from [400W if very good, 450W if decently] like 500w - 850W, for the average [gaming] user, I would say anywhere around these estimates, depending on what you want to do with it. More particularly running multiple gpus.
I generally prefer the strongest single gpu than bothering with sli/xfire. As for the newer api way, which I think is much better idea, tho I don't think I will be doing this any time soon neither, and my reason would probably be if I could/want to run two cards and get benefits from exclusive features, without having to have a separate system to benefit from them. And/or you could bring some enhancement in performance without any harmful disadvantages.
But that being said, you are better buying a tougher more quality PSU, than going for the sole higher wattage. It's a good idea to go higher than "needed", as long as you don't need to drop the efficiency rating. Sorta like a thumb rule. Better get a quality 650W Gold [some like the SeaSonic and CoolerMaster are gold, but nearing Platinum] than going for a 750W Silver / cheaper quality. But honestly, that's just my preferences and these days, unless you are buying some really trashy PSU from some weird brand you will not have regrets. :P
except it does make a difference
Great video/topic Jay. I've built many PCs and I've always wondered what the preferred method was to mounting the power supply. You made me aware of things I hadn't thought of. Thanks!
this is a good idea to know. never would think about which ways to mount a psu. i had always mounted psu down and not up cause it was never a gaming pc. the gaming case ps i have i just learned something about which is a better way to mount the psu. so i did mount up to give inside my case a better air flow. thank you for this video. always learn something new know matter how old you are.
Nice video, More 80s jokes in the future, please
0:02 i could tell by your hands you had a big youtube audience.
When he said "pour your sugar on me" I just started singing "In the name of love"
My take away, you just got a second fan (myself) pushing old air out meaning more fresh in. I almost set it fan down because the print would be right side up outside of tower where it would be plugged in. Well that's a DUMB reason to mount it if the fan mounted up inside and there's plenty of free space for the fan on the power supply to draw air out of the tower. Remembering that getting fresh (and cooler) air into the tower is just as important as exhausting the warmer (and older) air. Well, least he gave good reasons to mount it upside down? Yes he did. Thanks! And now I know the reasoning behind it too! And that's half the battle, understanding WHY you set the system up as you do it instead of using your solid but flawed logic because there are just some things you personally don't understand that can and will bite you in the butt later. This suggestion is a minor one but get enough minor ones and it turns major eventually.
Hey, Jay! Remember top-mounted power supplies? No shrouds, sometimes the only exhaust fan in the system? Couldn't flip them if you wanted because the screws wouldn't go in that way? Cable management meant stuffing them into the unused 5.25 bay that didn't have an optical drive in it? Good times.
I am feeling so old now.
AAAA only one waiting for the results of Trump vs Hillary? :C
Jona no
k. Starting right now
i wager 10 nano-dollars on clinton
what about BitCoins?
well good thing it was only nano-dollars, cuz it's looking like trump grabbed clinton by the pusssy , holy fuck were the polls wrong
wouldnt the air in the case be hotter cuz its being heated by the cpu, and gpu
That was happening to me with my built. The hot air from the case was f*** up all my PSU until one day I decide to flip it down and from then on never encountered air flow problems with the PSU.
Yes ,that's why psu manufacturers always recommend fan down, it's nearly always better to intake fresh,filtered air for PSU ,CPU and GPU and let case fans exhaust hot air from case, positive pressure also helps as it forces hot air out of the case as well as reducing dust.
Who needs 1200W for his PC?!
A good margin for newer replacement builds in the future.
@@TheRealFobican As long as you don't put three overclocked high end GPUs in your system you won't need 1200W.
@@uzefulvideos3440 I meant that you don´t have to worry about getting a new PSU for your next PC and the PC after the previously next PC.
higher power bill no thanks i much rather have lower like 350W
@@andrewdupuis1151 A perfect power supply would only use the amount of power it needs to provide.
Real power supplies are generally more efficient when you use more than 50% of the power they can supply.
If the PSU fan comes on, that means the PSU is running hot and needs air flow to cool down. Ideally, you don't want to be venting hot air inside the case through the PSU to cool the PSU down. Mounting the PSU fan downwards is the best option for keeping the PSU cool so long as the other safeguards mentioned are met (like no high rise carpeting and an airgap between case bottom and floor) and so long as there are at least a few vents in the top of the PSU enclosure allowing the hot air to escape and be sucked out of the PC case through the case's upper exhaust fan when the PSU fan isn't spinning. The air loop scenario mentioned is only a problem if the computer case is land-locked inside a cabinet, otherwise the hot air is projected outward and upward from the rear, which actually helps to suck cooler ambient air from the front of the case up through the bottom vent.
If the power supply is mounted with the fan up, and the graphics card has an open air cooler, they would both be fighting for the same air, especially if they are close to each other. Just a taught. Great video by the way.
