Dead PSU in this old i7 build - Good example that just because your No POST has lights, fans and sounds, it doesn't mean that the PSU isn't the problem.

Thanks to music bros down below!

you really, really have to stay until the end with this. amazing.
I've taken many faulty power supplies apart over the years, but never ever seen that much dust in one PSU!!! That certainly takes the biscuit ;-)
Yes, Geoff, it is a doozy eh. I am surprised it didn't combust with the combo of the dust and heat. Maybe there was too much dust. 😁
thanks for "after dusting" image omg
I've seen some really filthy power supplies but that one has to be a Guinness Book of Records contender.
Excellent video as always :) I'm a new viewer. I found your channel the other week via your Memtest video, when I was in despair about my PC possibly being broken and not having money to buy a new one or get new parts. Long story short, RAM wasn't the issue, but the video helped a lot any way.
I enjoy your style of video and it's nice to hear it all explained by a fellow countryman. I've been checking out a lot of your other videos and seeing how you handle each different device and scenario has helped me learn more about my computer. I've even adopted the techniques you used in your LFC #106: Servicing video, and seen significant improvements to my PC that I was ready for taking a hammer to. My PC and the moths in my wallet thank you.
Keep up the good work!
The plastic sheet in the PSU is actually a blast sheet. It covers the parts of the parts of the PSU that could emit a blast or sparks out of the fan or a vent if it goes pop, mainly the AC inputs and conversion. I used to have a job repairing those and server PSU's. That is one of the dirtiest I have seen in my time.
The dust looked like the owner was a smoker or lived with someone who smokes a lot. That is some super fine dust buildup.
Smoker dust turns into a thick yellowish/dark tan color and is caked on thick not fine, but at least we all know where you stand on smoking, For whatever reason;)
@@wolfchacer0139 cigarette ash is super fine and stinks so bad and knowing smokers not all of it ends up in the ashtray. My old PC had a ton of similar dust build up from when I was younger. Now I don't smoke around the PC anymore but that's because the kids use it sometimes.
Source: am smoker.
@@LadBooboo Yeah but with humidity in the air and other particles it becomes this sick Yellow/Brown gooey form on fans and other parts. I build and repair PC's for a living and this here looks far more like neglect than any cigarette induced mess and is more typical.
LadBooboo my grandfathers old dell desktop has a lot of cigarette dust buildup. He doesn’t smoke, but my uncles did. They never smoked around the computer, or even inside the house. The residual smoke was enough to collect inside it.
Great video - as usual!
Two comments, just in case you really read all "old" comments:
- Regarding the time it takes for the CMOS to reset: From my experience, the CMOS is gone, once the battery is out. Like within a second. I never managed to pull the battery out and put it back in right away without the CMOS being cleared. The "PP_3V3_RTC" - as Apple would call it - has basically no bulk capacitance, since it draws zero power, like literally
25:45 Loooool, the almount of dust... 🤯
Would've liked to see a good clean of that PSU just to see how the caps looked - might have been worth saving at that time, at least for kicks....
Sounded like you had a serious lisp with the mic broken. Good video, thanks!
Looks more like X58 with that triple channel memory, always thought they were pretty cool, IIRC first gen i7s and high-end i5s didn't have iGPUs, only i3s and low-end i5 chips had integrated graphics
Hi, I support you on fan positioning and air circulation. I've been in the IT industry a long time, like you, so have come across a lot of systems where tons, and I mean tons of dust has been removed froma machine. The problem with fins mounted downwards, especially if the PSU is to the bottom is to do with where the case is situated and the air flow requirements of the case in a given installation situation. What's made worse is the amount of fans installed and which direction they are circulating air, which can either draw dust in or send out. of the PSU is to the floor, the fan must be faing up not down, why? if the fan is facing downwards, there is the high risk of an overheat and potential fire hazard. I always say that it's best to show a system owner how to clean and remove dust from a machine, whether a laptop, desktop or server unit. I get so annoyed when someone doesn't look after their investment, yes, it's argued that's money in technicians and IT contractors pockets, but at the same time, it shows little care, knowledge or respect from the end user as to looking after and maintaining a system they've either purchased or built. Keep up the amazing work love listening to your videos, yes, listening to them I am registered blind so a mac technician and using a screen reader to manage all this.
BRB, gotta take a look inside my box.
I clean it from dust twice a year, but this just gave me nightmares!
I've never seen that much dust in a psu before. I use a brush and vac to remove the dust and if the psu is outside warranty, I open it up and brush it out, going outside to do it...always worth a look at the state of the caps.
I always check the 12v, 5v and 3.3v with a meter.
Nicely done. Visual inspection is very important so unnecessary work isn't done.
However since there are multiple RAM sticks, I would first take each one out in a sequence and see if that makes a difference and see if any RAM slots are dead. Also as you did, defaulting the BIOS is one of the first things to do when.
Also I use multimeter to check if the PSU is outputing right volatages, 5V and 12V in particular.
I mean the order which you do things doesn't really, but taking all the wires out only to conclude that the PSU isn't dead is just unnecessary work.
This is just my own preference however at some point you will go through these things anyway.
I could feel my self sneeze a bit, watching all that dust in that powersupply. Poor thing!
Urgh! That dust at the end. I feel sullied.
well made video l didn't know about the fan reverse
I still have that OCZ power supply in my downstairs comp. still works fine but I always kept it clean.
Did you test the powersupply after dusting it? I'm genuinely curious if it was one of those cases of the dust literally causing the issues or if the powersupply ittself died.
Also looks like i'm going to have to deep clean my powersupply after seeing this...
Old PSU may work but it's no longer reliable. Common failures are capacitors deteriorating thru time and last thing you want is a computer that will suddenly not turn on when you really need it to. Plus there's a possibility of it going out with a bang and damaging something else. Just replace the power supply.
My bet is that one of the semiconductor components overheated and eventually failed, possibly knocking out at least one power rail. The transistors, bridge rectifier, and voltage regulators in a computer PSU are on a heatsink, for a reason.
I think turning the psu fan up is fine as long as there is no shroud covering the psu be cause it could block off the air flow
* * * * *
Nice thing about using the Corsair HX1000i is that even while gaming GPU up to 376w / CPU up to 150w + everything else is that the fan like never kicks on. I'll check the filter once a month and it's always completely clean still 😂, do have their RM 850x as a backup lol
triple channel memory is one of the x58 characteristics its first-gen
I wasn't expecting you to make such a wrong assumption on this one
Dude just because he runs a computer shop doesn't mean he knows everything about computers how can you not understand that
Is a miracle that power supply didn’t catch on fire.
A couple days ago I FOUND a system - SABERTOOTH Z97 MARK1... it does not post...
After watching your video I may just go directly to the POWER SUPPLY!
I've seen some bad Power-Supply units - but never one like you showed here...
Cheers..
Hi Adam do you not have any Post diagnostics cards in your IT toolbox?
They are usually useless but sometimes just sometimes they do come in handy!
I have seen some furry Psu's but that one takes the biscuit - guess your customer is a smoker then!
We should send him something like caps and thing great show love watching him show time keep going mate love show
Wonder if after the dusting it worked fine again.
Is the card at 8:19 one of those fake 1050ti or similar graphics cards that were quite commonly found on sites like Aliexpress, ebay etc?
Clearly a good power supply. It stood up to years of dust, getting thicker by the day and finally failed at about the time that the PC became fairly worthless and slow for gaming. Built to exactly the quality you need :-)
My OCZ Fatality 750 Mod PSU is still going strong after 10 years still using it for my new build Ryzen 3600
I would have had a gas mask on your lucky you survived
My ocz ssd died, the only ssd i've ever had die yet. ocz stuff was nice when new like you said but didn't last. I was running an i7 960 and a sapphire pure black x58 motherboard, later i upgraded to a xeon x5650.
Just a quick question, I love watching your videos. What do you do for static management? I might sound stupid, but, does your jumper carry a static risk, I guess you are grounded through the PSU or Case....
Myself, basically nothing. The local humidity is high enough that static doesn't really build to any level that's a danger to PC components. I've never taken precautions, and never damaged anything.
However, in other countries and other weather patterns, it can be a different story. I don't think it's something the average person needs to worry about, but then I've also had comments from people who live in Arizona's 2% humidity and get static shocks from anything not nailed to the floor.
@@Adamant_IT Sometimes in the UK I feel like a walking Van de Graaff generator, both my home and artist studio is full of carpeted flooring. :D I like to mess around with self builds but I do worry about static.
A big soft fluffy cloud of dead human skin.
Hey adamant, I have a problem, not related to the video.
I disassembled and assembled my laptop,
Removed CMOS to reset BIOS.
Some of the keys are not working now,
Keyboard connector is fine.
Can you PLEASE tell me what could have gone wrong.
It would be a lot of help. PLEASE
Not the respondent you asked for but here goes anyways. Those laptop keyboard ribbon cables can be particularly finicky, sometimes simply disconnecting it and reconnecting it can fix an issue that was due to a bad connection. I've had to trim the cable ever so slightly (half a mm or so) once or twice to get one working properly. Worst case though if the keyboard was somehow damaged when you were working on it a replacement for most laptop models is generally under $25 shipped, so if it is bad it's not an overly expensive fix.
I've had mixed experiences with OCZ, they're sata SSDs are generally pretty good (I've only had one die). But they're PCIe SSDs are awful. I bought two RevoDrives and they both died, they were replaced and they both died too. 100% failure. I realise this is a one year one video but did you try that PSU again after cleaning it?
You worried about dust bunnies, when there was a dust T-rex in there!
Hey I've got a Asus z270-a with i77700k that a kid delidded said it woked for a bit got hot now it cycles on and off when I got it, I cleaned the chip and socket reapplied good thermal past under the lid and it remains on but no video out put to the hdmi port. It lights up cycles the fan just no video. So would trying another cpu be worth my while or is the board shot too? And do you have any other trouble shooting solutions i could try? Again thank you for the last answer and help you gave me and thank you in advance man.
Only way to know is to change the CPU or Mobo. Normally I'd say It's Never The CPU (Except When It Is), but with a delidded CPU... it's probably the CPU.
That power supply couldn't breathe at all with all that dust - no wonder it said no more - that's a horrible amount of dust - WOW
14:41 what is going on on the right side of the bench!?
Have to Admit OCZ did make some decent stuff back in the day had a few of there agility 3 SSD's running in my old FX system excellent video mate keep up the good work!
had an old h97 with an I7 4790 and 16GB DDR3 1333 ram CPU ran at 3.60 and 3.93 turbo it died so got a Z97 and 16GB DDR3 1600 ram to replace it and it runs at 4GHZ on all cores all the time. do not understand how the CPU runs on always turbo faster than its rated turbo being a locked CPU. not a big tech person so forgive me for being dumb, just would like to understand why this happened and is it good or bad and you seem like someone who may hopefully have an answer that I can understand.
Would have been interesting to see which rail, if any, had died - It could just have been the PWR_OK signal.
When you mid broke I expected you to say "now on Radio 4 longwave...." :D Seen worse power supplies and cpu coolers from peoples houses that are heavy smokers. Solid with tar and dust, refused to work on them.
there's a mouse looking for his nest
21:57 ask a dumb question I see that HD isn't connected to the board SATA port see it in the HD
I have an old x58 Supermicro Workstation board and noticed that the IO hub chip gets really hot, wonder if there is a better heat sink than the one I installed. I have 20 gigabytes of memory and noticed with the addl memory the board gets hot. Should I put heat sinks on the VRM modules by CPU? or should I not worry about it? The IO hub or Northbridge chip has a heatsink w fan, but peaks in temps of 107 C but drops to 87c when idle. Low budget install, thanks to Ebay and the Xeon 6 core x5800 CPUs. -- even if board goes bad, only cost me $42.00 US
Replace the thermal paste on the north bridge
I've heard a novice isn't supposed to open a psu as the caps can still hold enough charge to kill, even after days or weeks of being off. Can you explain where we should NOT touch?
Inside the PSU is the only real no-go area unless you know what you're doing. Everything else in the PC is low-voltage. PSUs are not user serviceable anyway. They can be repaired in certain circumstances, but it's absolutely not a DIY job.
Don't go near any big capacitors in anything without discharging them. Big means high voltage; they can have charges equivalent or higher than your mains outlet. Learn where AC ends and where DC starts since DC is commonly safe.
Rectified mains in the primary side of the PSU will be up to 340v DC in the UK (mains/0.7071). That's why the big primary caps are typically rated for at least 400v. This circuit should be designed with bleeder resistors to drain the caps quickly on loss of power, but never assume.
Watching this upload in 2021, I have exactly the same PSU bought back in 2012, with a Ryzen 3600, Asus 570 mobo, corsair RGB RAM and old R9 280X suddenly getting random lockups and BSOD's - minidump all mention power issues..................... Today I spunked out for a Corsair TX-M 850 Gold..
I have the same model O-C-Zee power supply, working since 2013, with no problems. I just replaced it, just 'cause I could. Even though it might have been the modular cable for the GPU, it was probably time to retire it.

po-tay-tow, po-tah-toh@@crylune
so i have a weird issue. when i have my back panel installed the pc will randomly shut down and wont turn back on until i unplug the pc and plug it back in. the power supply seems fine and ive confirmed the problem goes away witht he panel off and the power supply not secured to the case with the screws. is it some sort of grounding issue?
Are you certain that the IO panel isn't poking into one of the USB/Ethernet ports?
@@Adamant_IT well first off thank you for taking the time to help me. looks all clear to me and i pressed on it all around and all is good. i should clarify though. by back panel i mean the one thats meant to hide all of the cable management. (back side of mobo)
my allergies got triggered just by seeing this video
would removing the dust then allow a cheap component repair?
While this might be filthy its likely not the cause of the issue due to the age of the machine and would have been entertaining to blow out and look for actual failed components
sweet i always know it will beep by watching the cpu fan speed up slowdown and speed up again
With no videocard there is no bios image, true?
Because there's no on board video to connect the monitor too.
Reaching for hayfever pills
actually still have and use ocz ssd, i wonder when it will fail
Did you try the psu again after dusting?
I'm liking, sharing, subscribing and commenting so that you say "z" as you would say in the alphabet not "zed" like you are adding on more letters to "z".
*Zed
Upgrade the CPU to a xeon 6-core and overclock the cpu and a better gpu and you still have a great gaming experience
yes in that case only way to mount power supply
Is the un-dusted PSU still broken?
when your 2019 mobo has a 4pin cpu connector and a 2010s mobo has an 8pin cpu connector
its an overclocking motherboard
I'm going with GTX 950 or 960 for my guess
I run Lga 1366 with P6x58d-e and OC x5670...with 6 x 2gb Ripjaws...Memory failure is normally the downside of most x58 boards...😏
It‘s a first gen i7 x58 chipset
Think the videocard is a wish /AliExpress 1050/Ti with a gtx460 core or so
is that a fake 1050ti from wish? ie a gts 450 thats been reflashed?
A good upgrade for this is Xeon X5680 6 core, update bios and OC to 4ghz !
Or the W3680 or W3690, both of which have unlocked multipliers, therefore simpler to overclock and even possible to overclock on OEM prebuilt motherboards using overclocking software! With 4GHz you'll get up to 85% the performance of a Ryzen 5 1600, with same core count as the R5. Not bad at all.
Just watched. So I was thinking the “extension power connector “ could of been the issue to the cpu. Still good idea to change PS, but you should of checked the extension...
Zed's dead baby, Zed's dead...
That is an X58 board with triple channel DDR3 I have a Sabertooth X58 with a Xeon 6 core 4.00ghz and 24 Gigs of ram in triple channel
Pretty sure OCZ was just rebranded stuff.
25:07😨
What does wanker mean?
8:19 itz an ebay scan card, or wish or...anyways itz a scam
This Faulty PSU is definitely reusable after some maintenance or repair .
He would have to safely discharge the thing first and even then it's still risky pulling the thing apart. If it's on DDR3, its bound to die again because of its age.
i really don't understand how people can let there machines get this bad with dust. i prefer to mount the power supplies the same way as you do.
considering dust is mostly dead skin, that clumpy mess was pretty disgusting. It's like cleaning someone's dirty diaper.
Actually too much thermal paste is a very bad idea as it gets to a point where it actually starts to act as an insulator rather than a conductor!
Less is more when it comes to TIM!
this is not really true, check gamers nexus thermal paste application video:
ua-cam.com/video/EUWVVTY63hc/v-deo.html
It's safe to say, that psu was working in zombie mode......
So it's a "ZED-bra" .. who'd a 'thunk' it? 👍😎
Not all i7 cpu's have built in graphics no. In fact it was pretty common some 15ish years ago to have onboard video on the motherboard, some crappy shitty one tho.
Keep saying Zed instead of Zee. As an American, I saw Zee, but to me, Zed sounds much cooler
Yep. I had a Nissan 300 Zed Ex and I have two Sinclair Zed EX Spectrums :-)
@@tenmillionvolts
I have an 05 Mustang GT Premium in stick. No where in that sentence can I use Zed, but you mentioned cars so
gtx 580 or something like that
That mystery GPU is a wish.com / aliexpress graphics cars isn't it!!
Can you save all the small videos of simple fixes and just do a big compilation of you opening pc's and being like " well this ram isn't in all the way" and then the computer working 😂
Mine has a corsair 1000w
Computer: *won't POST*
Power Supply: 25:46
2nd gen i7 doesn't have triple channel memory haha
.The not a 1060 5 gig, china wonder
You dont need beep codes to see its not posting.
@mister.T Jr Nope. Lots of faulty video cards and ram sticks don't trip codes, the mainboard thinking there fine but no post or intermittent. Keep some spare components handy for quick dirty diagnosis.
Could a power supply catch on fire with all that amount of dust inside it ?
I suppose if something went bang spectacularly, the flame could start the dust burning, and it spreads from there. Not something I've seen or heard of, but I can imagine this being the method by which electrical fires often start.
Take a pic and give to customer
Never seen a dusty PC component like this.

Why is this on my recommended.. hmm
