Being a tech enthusiast site, a 'quick' video on UPS buying should include the critical piece of advice to make sure that if you are using a modern mid-high end power supply(pretty much ANY power supply with an 80+ rating of any kind), it will have Active PFC. This REQUIRES a power supply that can output a pure sinewave(or as close as a digital device is capable of delivering). Many low end models deliver stepped sinewave power which would be perfectly fine for charging your cell phone, but your computer will just plain not work. So when it switches to battery power, your computer will just instantly shut off. Make sure you buy a power supply that is stated as compatible with active PFC power supplies.

When I built my desktop I made sure to get a ups as a means of protecting it from sudden shut downs and surges. I got a APC 850 VA for around $90 on sale and that will run my desktop on idle (45 w) for an hour or under a heavy load, like a game, (~200 w) for 20 minutes. It also probably saved my PC from receiving a pretty powerful electrical surge that blew up an old surge protector plugged into the outlet by switching to batter power as soon as it sensed fluctuations in the voltage. That $90 investment might of saved my $1000 build that was less than 2 months old at the time.
Couple of points that have been missed: Some UPS have the system run through the battery the entire time, while others only switch over to battery when it senses a problem. In that case, you need to make sure the UPS is fast enough before the stored electricity in your computer drops and the comp turns off anyway. Also, some UPS have phone and network pass through to protect you from surges through the phone/internet lines (lightning strikes). Many also have plugs that on the UPS that dont run through the battery. These are for surge protection only, but wont drain the battery in the event of a blackout. Good for running multi-monitor setups. Not to mention the idea behind smoothing out the line power itself for power that fluctuates, but doesn't necessarily create brown-outs that you can notice. Less than 4 minutes of content and you missed so much.
That was my first thought as well. The most important characteristic of a ups is is working mode (offline (which replaces the line supply when it goes down), line interactive (a step up that will take over if the line is too bad), and on-line (which is always charging and powering the batteries at the same time for perfect power output at the cost of replacing the batteries after a few years)
online UPSs dont run on batteries the whole time. they convert the AC input current to DC, then back to AC again for your sensitive devices. when the input AC goes out, the internal DC power is instantly switched to the battery source and then converted to AC via the same circuitry that was powerwing the protected equipement prior to the power outage. the onlineupss have ZERO transfer time..
@@lethauntic APCs are quite good in my experiences, seems to be replaceable on anything better than the VERY low end models. Plus they even support Linux out of the box. :)
You guys failed to mention that there are different types of UPS output such as quare wave or sine wave making them not compatible with all power supplies...
why would we need a true clean sine wave when every pc power supply in existance uses full bridge rectifier anyway to get pulse dc voltage as a first block in the chain so we get same shit in the end ?
A lot of power supplies nowadays, if not all, use/have Active PFC which doesnt go well with Square Wave UPS causing sudden power offs or the power supply not work at all. So yeah, it matters, you dont just send garbage power into it with a bit of magic dust to have a perfect output...

Pure Sine Wave UPS are called 'On - Line Ups' these provide purest and clearest forms of DC current to your pc components without any ups and downs in voltage
@@varunthapliyal8960 load-shedding is regularl in my area. I've heard offline ups contribute into destroying your pc. It is better to go ups less than using offline pc. Is it true?
@@varunthapliyal8960 There are line-interactive UPS models with pure sinewave output as well. I prefer them over online ones for personal use, as they only kick in when needed (voltage fluctuations & blackouts), which makes them run cooler, way more silent (either fanless, or fans kick in when battery is in use / high usage), and batteries themselves last much longer.
You forgot to mention the part where some UPSs come with stuff like LCD monitors to display power in and output, manual key controls to make adjustments to get the best possible Sine wave and bunch of other connectors like, micro USB B, USB 2.0, optical connectors and most importantly, 'circuit breakers'. Btw, I am just filling in the holes, I am not an expert or a critic and I love you guys. Awaiting new episodes and seasons of Scrapyard Wars.
4:00 "Audio books are great to listen to when you're sitting on the subway, sitting on the train, sitting on the bus, sitting on the uhhhh..." ...toilet?
Thx, slick,... was just now jumpin on the UPS train since deciding to build a NAS, and this video was helpful with the immediate confusion I ran into when researched UPS's haha
it's sort of odd to see people actually not know what a ups is since power cuts are so rare and you don't need them. where i live, power outages are not as rare (once a week in summer and once a month maybe in winter)but the probability of them happening is high enough that everyone who even considers building a desktop has to first ask what type of ups they should be getting
I was looking for a ups surge protector today, and like magic you guys posted exactly what I was looking for and helped me make the right purchase. Thank you.
after the part that has to to do with the volt-amps and watt stuff (1:50) I'd've liked an example where you showed some quick math. I feel like that'd really help a lot.
S*S=P*P + Q*Q Where S [VA] is the apparent power P [W] is the active power Q [VAR] is the reactive power also ϕ=atan2(Q/P) and cos(ϕ) is the displacement factor (that's equal to the power factor in the linear case)
If your power supply supports PFC (Power Factor Correction), make sure the UPS supports it. For example, with CyberPower, the AVR UPS line is cheaper than the PFC, but it's not a good choice for my Corsair RM750x.
I discovered recently that some forms of Linux will display the battery level of a UPS connected via USB in the same way it would show battery life on a laptop, making it easy to see right from the desktop.
This is one of the reasons I use my laptop as a desktop replacement....it's a layer of protection a regular desktop doesn't have...I still use a UPS for other stuff on my desk though and have the laptop plugged into the surge protection side of the UPS
Keep in mind the efficiency of the PSU so if you have a 85% efficient power supply, you will have to factor in that 15% loss and add it to the UPS rating since it will be drawing 15% more than it can give out from the UPS.
And here is what they forgot to tell you: Cheaper UPS units do not produce a true sine wave AC power; instead they produce a square wave that mostly matches an AC sine wave. Some more expansive UPS units like Smart UPS from APC will produce true sine wave output. Why does this matter? Two reasons, if you thinking of nesting 2 cheap ups units by plugging one into the other to double battery life, that won't work; b/c second ups will reject the square wave from the first ups treating it as bad power. Also, running a square wave AC CAN DAMAGE your hi-fi audio gear, so if you paid $500+ for a fancy receiver and speakers, spend the $300 to get true sine wave UPS.
+Igor Petrusky I was going to type this info up myself! A very embarrassing oversight IMO to not have mentioned the importance of understanding and purchasing an UPS to match your Active or passive power supply! Buy the wrong kind and you ruin the UPS within 6 months.
Something I want to add. If the devices connected to ups have ac/dc converters on them, most likely the squarewave ups will be ok, bc the acdc converters usually use bridge rectifier, which does not care about true sin wave. But for oldschool analog devices driven directly by ac a square wave can be a no-no.
VA is not the same as Watts not because of resistance present in electrical load but because of reactance. Reactance is almost always undesirable in load.
+Shagas Heizenberg True. VA is the apparent power. In the power industry, people try to make VA equal to the real power by messing with banks of capacitors. The ratio between those two is called Power Factor. A good power factor is about 0.95 (maybe 0.93). Anything below that is a huge waste of power
I've seen and worked with a lot of UPS units from cheap home ones to server room 3500VA models. I don't care much for APC UPS because they have been known to just charge the batteries constantly and burn out the batteries. So far the best UPS I have run across is the Eaton 5P 1000 model. From what I can tell it is a line interactive model.The only cons are it has a small fan, and I think retail is like $700-1000, if you want the LAN mgmt card I think that is like $150-200 more. There are also 2 types of UPS the sine wave models (primarily older models). Or switchmode UPS which works like you PSU just in reverse. The boost transformer is small and driven by a high-frequency SMPS driver. Usually the switch mode UPS are lighter, but that can be hard to tell just from that because some like the 5P1000 have a large transformer for the line interactive part which throws that result off.
For those of us still trying to decide which UPS to buy, there are those that say APC are the best, others that say CyberPower are the worst or best, etc etc etc etc.... what a nightmare! Personally, I'm going to go with an APC, I particularly like the facility on some of their models which enable you to connect multiple UPS's together to get longer battery time.
IMO every computer should have a good UPS, especially if it is a workstation. The power cleaning alone will save you so much uncertainty with PSU's and Mobos and theoretically make them last longer. The only tip I can provide is if your workload maxed out is 450 watts like mine is (on a 750 or 850w PSU) then you really do want a 1500 VA (865w effective) UPS. This will allow for multiple screens, speakers and quite a few peripherals to stay function for the 6 or so minutes that the battery can sustain at full power. It's also a 2nd backup for RAID5 power loss so you're not depending entirely on the onboard battery backup. It's actually better because it's enough time to flush the ram to drive and have no worries about stripe corruption.
P=IV is only watts in DC... When you go to AC capacitive and inductive effects mean that load has a complex component as well. THAT is why UPSs are rated in VA. Typically It's the battery Ah rating multiplied by the RMS AC voltage. In addition there are losses from the DC->AC inverter as well, meaning the output power rating in watts is less than the VA rating of the battery. Ultimately what matters is 2 things. The size of the battery in Ah (determines how long it can keep your devices powered) and the max load of the Inverter in Watts (determines how much it can power simultaneously)
I was hoping the video would go into some detail on choices or different brands and types of UPS to buy but nope. Just buy the most expensive one out there right TechQuickie? PS - Government liquidation auctions are the best place to buy older high-end UPS (especially in bulk!) Just buy aftermarket batteries and you got yourself one hell of a backup.
I had a UPS about 12 years ago whilst at University and I was gaming when the power tripped. My friend was writing a last minute Essay but lost his work. I was playing Half-Life all I didn't was walk to the electric box to switch the power back on. I would really recommend a ups.
I can't stand UPS delivery, they do a crappy job. It's like they DON'T want you to get your item the fastest so they just leave a note and run (I was here all day, no ringing, no knocking) which means I have to go out of my way to get to their "closest" pickup spot which is usually far /grumble
+Phantasmal Wordsmith that sucks, where i live we have a rather stable power supply, albeit we have overhead service and there's a ton of trees so a tree can easily knock out power, but even then it's just for an hour or 2, the last blackout we had was during a windstorm, it wasn't a tree falling, but a short somewhere in the grid caused a transformer to overheat, it's safety mechanism's failed, and next thing ya know there's a substation fire, took them a few minutes to cut the power though, it was a good few hours until they had the power re-routed and it was back on.
I am more interested of modern options like lithium ion, graphene, etc. I am still wondering of the days of getting even Teslas on the cheap, surely there would be cheaper 1KW or larger UPSes?
@Techquickie Could you guys update this video for 2022 with a top 3 or 5 list. I’m moving soon to an area that loses power often. So I’d love to make the right choice when buying a UPS.
I have 1600VA UPS and 300Ah of tall tubular battery, oh baby I rejoice power outages, gaming while hear the UPS of other people screaming as I game for an hour. Now that's an investment every gamer should do.
UPS attached to UPS attached to UPS attached to UPS, attach multiple UPSes at once longest power method so when the power goes out you have longer time to use the UPS
Would also recommend you guys mention Pure Sine vs Simulated Sine waves. From what I understand simulated sine UPS's are cheaper but may harm components such as screen back lights. Great weekly vids guys!
@@kiskiller3 APC units will let you just hook up the "monitoring" USB even to Linux. Shows battery life, time and even let me have the option to shut her down should the battery runs on empty. No need to use their shit software.
I have i7-4790K and use Line interactive UPS 600 watts capacity, which is only connected to PC. While a second setup i use is 900 watts inverters with modified sine wave current with 200 amps storage acid battery and i also use AVR with it, it is connected to whole system, monitor, pc, printer etc. I also have another big stablizer incase electricity start fluctuating too much. Entire backup system costed me about, 400+ dollars.
AD KN I live in africa power cuts 4 - 6 times a week for long the normal setup here is 1500VA inverter with 9 x 12V 200AH barttery some people have here even way more VA inverters
I had pretty much same in first time. I used 200 amps battery with 900 watts inverter, also added AVR which gives pure sinewave current. But as soon as electricity goes out in rain, or heavy fluctuation, my PC got restarted. So i added another Line interactive UPS. Now it works fine.
+sircolby45 Yeah, I'm surprised this video didn't mention it at all. Some power supplies that emphasize power efficiency (especially 80 Plus certified ones) will depend on clean, consistent pure sine wave, instead of the approximate step kind. When I bought my UPS a few years ago, I was going to buy an APC brand unit that didn't have pure sine wave, and I found my PSU (Corsair TX650) has issues with non-PSW UPSes. I bought a CyberPower 1350PFCLCD instead and it's been fantastic. I even bought a second for my living room.
@@traviscombs6947 That's absurdly weird, even the cheapo non replaceable APC unit (it's was like 450VA or even less, rated for 255 max wattage) did just fine service for my Corsair 650 watts PSU and it is a bronze power supply.
Some UPS have the option of being powered and charge its batteries form solar panels. If your home have solar panels installed or you plan to dose you can use one of these with adequate capacity, and you may be able to pull part (all) of your home off grid, running (almost) entirely off solar power.
Surprised (and a little disappointed) that you didn't discuss the importance of "square sine", "simulated sine", and "pure sine" UPSes and what sort of equipment needs what quality of power. Rule of thumb: Square sine should only be used for the most non-sensitive electronics. It's a very low-quality power that can damage whatever is connected to it. "Simulated Sine" should be used for computers, monitors, and LED, halogen, or fluorescent light bulbs. "Pure Sine" is for very sensitive equipment, such as speakers or audio interfaces, that absolutely need as close to real AC power as you can get it.
my APC UPS rates in watts, says max load is 865W with my desktop a 4790k/770/6drives/2monitor it gives me usually a estimated run time of 45minutes ,, been pretty dang good so far, i live in an area with tons black outs sometimes multiple in a day and alot of energy spikes, my apc has gotten through i'd say about 50 outages without a single issue
TobyDK91 yes and no... it is more like the old power lines we have aren't efficient as they could be/ storms knock them down, so the power goes out when you need it not to and when you least expect it, but it ultimately depends on where you live in the us/canada
Its measured in VA because it stands for apparent power and is all the power a battery can deliver. P stands for actual power, this is the power that is used to perform actual work. The difference between these two is caused by the fact the voltage not being in phase with the current this is caused by capacitive or inductive loads (not restive), the cosine of the angle between the voltage and current is called the power factor. P is calculated by voltage times amps times the powerfactor while S is calculated by voltage times amps. Therefore depending on the type of load the actual power to a device can be very different than the apparent power being used.
i wish you would have covered inverter types as well as whether modified/simulated sine wave inverters have any problems with 80+ PF corrected power supplies
i remember i had 3 blackouts out of no where in a row managed to malfunction my motherboard and force me to seek salvaged parts to make the PC work again so it can be useful depending on financial situation and how much you care about your devices
A UPS's voltage regulator will allow you to use old school or inexpensive generators. I used to work at a company that made UPS for mainframes and entire buildings. Best investment to protect electronics. Only big downside is the batteries need to be replaced every 2 to 4 years depending on the unit.
I wonder if they have in desktop tower UPS (PSU > UPS > Motherboard/components) because there are power losses from the battery charger going from ac to dc, then from the battery through the dc to ac inverter, and then again from the PSU when it converts the ac back to dc.
You forgot to mention that this can also protect you against voltage spikes. But the power supplie already has a fuse and the primary and secondary sides are isolated each other so its almost impossible to damage parts like cpu gpu mobo ram...
That was actually the first techquickie in a while that was interesting to me I feel like the content quality has gone down a lot for a couple months otherwise
Ah, the one piece of tech that my setup needs that I don't have yet, the backup power supply. Most recently, before I built my current setup, we had a very temporary (>30min) blackout at around eleven PM and that shut down my PC. It had to do some odd startup sequence and restart during this multiple times for the computer itself to actually start up again, and a UPS would've allowed me to save and shut down my computer before I actually did something or, even, kept it running through the whole blackout so I wouldn't have a problem. Still, saving up for one is problematic... wanting to get into the PC-building arena isn't exactly cheap... and neither are apartments, come to think of it...
they did forgot to talk about on-line UPS and its difference with line interactive ones, as well as their compatibility with the PSUs, based on the waveform they produce
CyberPower CP1350AVR or 1500VA AVR FTW These have saved my computer from both brownouts and regulated strange pulsing wire voltage that damaged my previous computers. It even logs the events. 2 years going so far.
I want to be able to run a presentation online for work without worry of a power blackout/brownout Say I have a standard 120V household power line, and want to run my PC for 10 minutes. The PSU is 600w, monitor about 60 W and I want to keep my modem running. The PSU is sized mainly for my GPU. Also, what must stay running is my wireless headphones and my Scarlett 212 and Rode podmic. The PC I would imagine would be running on minimum power for running Powerpoint, Zoom and a few other apps. What is the VA/W that I would need for a UPS? Thank you in advance
Waveform? I keep reading of certain power supplies needing UPSs that fully mimic outlet power for some reason. I have yet to have a PSU like that in the house. Still would have been nice to know if it is would be a good idea to buy that UPS type or not. As it seams to cost significantly more then the other model types. "The Girl With All the Gifts" is a pretty awesome read. I have gotten to the action part and have to say it is just the kind of book that makes for great listening. Doesn't do any good to have a decent UPS if the PC isn't set up right to take advantage of it. I am still not certain how to do that. I mostly just set the default Windows power features to force a shutdown while the battery still has a lot left in it. I am still remembering UPSs that would report a hour of run time to the computer and run out of power a minute after the power outage. That thing about what wattage to shoot for will help. I tend to match them up and not go over.
I've got a 1500VA pure sine ups for my desktop, server, 2 monitors, printer, and modem. Can run all of them for about 45 minutes tops. Use to be longer but I think the batteries have gone capoopoo on me.
Actually, line-interactive UPSes kinda suck. If you want a high-end one, look for "double conversion." They are not as efficient because your gear is always on the inverter, but it avoids the imperfections in the sine wave when the UPS switches over. For business use, we saw a huge decrease in failed hard-drives when we made that change. That said, line-interactive units are normally much less expansive than double conversion units.
It is not because the presence is resistance that causes wattage is not equal to volt times amp. In an ideal resistive load, P=VI. The reason we have VA product usually higher than real power is because the load ia not perfectly resistive. For an ideal resistor, the instantaneous current flowing through equals to the voltage applied instantaneously divided by resistance. Other loads are not. They have a lag between current and voltage, called phase angle. If voltage and current are completely 90 degrees shifted, no matter how much current or voltage, you do not have any real power. As the phase angle shifts from -90 to 90 degrees, your real load power goes from 0 to ideal, V*A, back to 0. In the second and third quadrant, your equipment will be sourcing power to the grid. Therefore, power supplies operate in quadrant 1 and 4, usually the current is a bit lagging. The cosine of the phase angle is called power factor, which is also the ratio between VA and P. In AC world, P=cos(theta)*V*I. Since most modern 80 plus power supplies has power factor correction units built in, the power factor is usually higher than 98%. So, the VA input will be almost the same as real power draw. The VA rating of an UPS is determined by its output stage's capability, and the P rating is determined by its battery to high voltage bus converter's capability. Be sure to consult the UPS's manual or an expert before choosing one.
Just get a UPS designed for loaded server racks. If we lost power at work, our UPS's would keep 6 servers running for up to 1 hour so for a home PC setup, you'd probably be able to carry on playing games until the power grid comes back online.
And where, pray tell are you going to put all those batteries? They're exactly cheap either and they weigh (literally) a tonne if you're talking that kind of backup potential.
I got a 1500VA Cyberpower UPS on sale, for just under $200. It gives me almost 30 minutes of run-time my rig is mid-range by today's standards. I'd say don't go lower than 1000VA in general to get half decent run-time.

You missed the part of needing a "Pure Sine Wave" UPS for Active PFC PSU's.
Finally someone... I had to scroll too far down
Explain, I’m new
Pure Sine Wave UPS are called 'On - Line Ups'
these provide purest and clearest forms of DC current to your pc components without any ups and downs in voltage
@@varunthapliyal8960 load-shedding is regularl in my area. I've heard offline ups contribute into destroying your pc. It is better to go ups less than using offline pc. Is it true?
@@varunthapliyal8960 There are line-interactive UPS models with pure sinewave output as well. I prefer them over online ones for personal use, as they only kick in when needed (voltage fluctuations & blackouts), which makes them run cooler, way more silent (either fanless, or fans kick in when battery is in use / high usage), and batteries themselves last much longer.
You forgot to mention the part where some UPSs come with stuff like LCD monitors to display power in and output, manual key controls to make adjustments to get the best possible Sine wave and bunch of other connectors like, micro USB B, USB 2.0, optical connectors and most importantly, 'circuit breakers'.
Btw, I am just filling in the holes, I am not an expert or a critic and I love you guys. Awaiting new episodes and seasons of Scrapyard Wars.

+Dexter Dickinson You Should ;)
You should
it's sort of odd to see people actually not know what a ups is since power cuts are so rare and you don't need them. where i live, power outages are not as rare (once a week in summer and once a month maybe in winter)but the probability of them happening is high enough that everyone who even considers building a desktop has to first ask what type of ups they should be getting
I was looking for a ups surge protector today, and like magic you guys posted exactly what I was looking for and helped me make the right purchase. Thank you.
VERY helpful years later. Thank you guys!
Thank you!! Not many tech channels talk about this very much. :)
I just find this so much fun: 0:28, I could put it on loop and listen to it for an hour!😁
Great video as always!
after the part that has to to do with the volt-amps and watt stuff (1:50) I'd've liked an example where you showed some quick math. I feel like that'd really help a lot.
Animiles 2+2=4-1=3
Quick Mafffs
S*S=P*P + Q*Q
Where
S [VA] is the apparent power
P [W] is the active power
Q [VAR] is the reactive power
also ϕ=atan2(Q/P)
and cos(ϕ) is the displacement factor (that's equal to the power factor in the linear case)
If your power supply supports PFC (Power Factor Correction), make sure the UPS supports it. For example, with CyberPower, the AVR UPS line is cheaper than the PFC, but it's not a good choice for my Corsair RM750x.
I discovered recently that some forms of Linux will display the battery level of a UPS connected via USB in the same way it would show battery life on a laptop, making it easy to see right from the desktop.
Works very well on APC units apparently. So useful!
This is one of the reasons I use my laptop as a desktop replacement....it's a layer of protection a regular desktop doesn't have...I still use a UPS for other stuff on my desk though and have the laptop plugged into the surge protection side of the UPS
who else read the thumbnail and wondered what the hell "ups" are until they looked at the title and saw UPS? 😂
me
too
thanks
+Ali Adam i watched this vid solely to find out what it was
+Ali Adam -The title and the thumbnail appear to say the same thing.- *EDIT:* Oh, I think I see what you mean now. What up.
Keep in mind the efficiency of the PSU so if you have a 85% efficient power supply, you will have to factor in that 15% loss and add it to the UPS rating since it will be drawing 15% more than it can give out from the UPS.
And here is what they forgot to tell you: Cheaper UPS units do not produce a true sine wave AC power; instead they produce a square wave that mostly matches an AC sine wave. Some more expansive UPS units like Smart UPS from APC will produce true sine wave output. Why does this matter? Two reasons, if you thinking of nesting 2 cheap ups units by plugging one into the other to double battery life, that won't work; b/c second ups will reject the square wave from the first ups treating it as bad power. Also, running a square wave AC CAN DAMAGE your hi-fi audio gear, so if you paid $500+ for a fancy receiver and speakers, spend the $300 to get true sine wave UPS.
+Igor Petrusky
I was going to type this info up myself! A very embarrassing oversight IMO to not have mentioned the importance of understanding and purchasing an UPS to match your Active or passive power supply! Buy the wrong kind and you ruin the UPS within 6 months.
Something I want to add. If the devices connected to ups have ac/dc converters on them, most likely the squarewave ups will be ok, bc the acdc converters usually use bridge rectifier, which does not care about true sin wave. But for oldschool analog devices driven directly by ac a square wave can be a no-no.
VA is not the same as Watts not because of resistance present in electrical load but because of reactance. Reactance
is almost always undesirable in load.
yes it is
+Shagas Heizenberg True. VA is the apparent power. In the power industry, people try to make VA equal to the real power by messing with banks of capacitors. The ratio between those two is called Power Factor. A good power factor is about 0.95 (maybe 0.93). Anything below that is a huge waste of power
I've seen and worked with a lot of UPS units from cheap home ones to server room 3500VA models.
I don't care much for APC UPS because they have been known to just charge the batteries constantly and burn out the batteries.
So far the best UPS I have run across is the Eaton 5P 1000 model. From what I can tell it is a line interactive model.The only cons are it has a small fan, and I think retail is like $700-1000, if you want the LAN mgmt card I think that is like $150-200 more.
There are also 2 types of UPS the sine wave models (primarily older models). Or switchmode UPS which works like you PSU just in reverse. The boost transformer is small and driven by a high-frequency SMPS driver. Usually the switch mode UPS are lighter, but that can be hard to tell just from that because some like the 5P1000 have a large transformer for the line interactive part which throws that result off.
For those of us still trying to decide which UPS to buy, there are those that say APC are the best, others that say CyberPower are the worst or best, etc etc etc etc.... what a nightmare! Personally, I'm going to go with an APC, I particularly like the facility on some of their models which enable you to connect multiple UPS's together to get longer battery time.
IMO every computer should have a good UPS, especially if it is a workstation. The power cleaning alone will save you so much uncertainty with PSU's and Mobos and theoretically make them last longer.
The only tip I can provide is if your workload maxed out is 450 watts like mine is (on a 750 or 850w PSU) then you really do want a 1500 VA (865w effective) UPS. This will allow for multiple screens, speakers and quite a few peripherals to stay function for the 6 or so minutes that the battery can sustain at full power.
It's also a 2nd backup for RAID5 power loss so you're not depending entirely on the onboard battery backup. It's actually better because it's enough time to flush the ram to drive and have no worries about stripe corruption.
Surprising relevant; I was just looking at buying a UPS. Good tips!
P=IV is only watts in DC... When you go to AC capacitive and inductive effects mean that load has a complex component as well. THAT is why UPSs are rated in VA. Typically It's the battery Ah rating multiplied by the RMS AC voltage.
In addition there are losses from the DC->AC inverter as well, meaning the output power rating in watts is less than the VA rating of the battery.
Ultimately what matters is 2 things. The size of the battery in Ah (determines how long it can keep your devices powered) and the max load of the Inverter in Watts (determines how much it can power simultaneously)
I was hoping the video would go into some detail on choices or different brands and types of UPS to buy but nope. Just buy the most expensive one out there right TechQuickie?
PS - Government liquidation auctions are the best place to buy older high-end UPS (especially in bulk!) Just buy aftermarket batteries and you got yourself one hell of a backup.
Tech Quickie is just to explain it not to review or recommend.
I had a UPS about 12 years ago whilst at University and I was gaming when the power tripped. My friend was writing a last minute Essay but lost his work. I was playing Half-Life all I didn't was walk to the electric box to switch the power back on. I would really recommend a ups.
i live in a area with spotty power so buying a UPS was a must when i got my new computer
Oh, I thought this was about the UPS delivery.
me too
Fuck you
I can't stand UPS delivery, they do a crappy job. It's like they DON'T want you to get your item the fastest so they just leave a note and run (I was here all day, no ringing, no knocking) which means I have to go out of my way to get to their "closest" pickup spot which is usually far /grumble
@@dominicbeaudoin2762 never had a problem with them.
Buying a UPS has honestly been the single best purchase for my computer system I've ever made. Hands down.
Why? did it cut in on a power outage? Or is it the peace of mind it give you?
This is weirdly fitting. My mains power seemed to die a couple times - came back on immediately - just earlier tonight.
+Phantasmal Wordsmith that sucks, where i live we have a rather stable power supply, albeit we have overhead service and there's a ton of trees so a tree can easily knock out power, but even then it's just for an hour or 2, the last blackout we had was during a windstorm, it wasn't a tree falling, but a short somewhere in the grid caused a transformer to overheat, it's safety mechanism's failed, and next thing ya know there's a substation fire, took them a few minutes to cut the power though, it was a good few hours until they had the power re-routed and it was back on.
Ltt should really do an updated video about UPS’s. one that includes brand names and compares quality.
I am more interested of modern options like lithium ion, graphene, etc. I am still wondering of the days of getting even Teslas on the cheap, surely there would be cheaper 1KW or larger UPSes?
this is always a must have piece of tech in my home for sure no joke
@Techquickie Could you guys update this video for 2022 with a top 3 or 5 list. I’m moving soon to an area that loses power often. So I’d love to make the right choice when buying a UPS.
I have 1600VA UPS and 300Ah of tall tubular battery, oh baby I rejoice power outages, gaming while hear the UPS of other people screaming as I game for an hour. Now that's an investment every gamer should do.
I'm looking into a lithium ion UPS for fast charge times. My lead acids are starting to wear out.
UPS attached to UPS attached to UPS attached to UPS, attach multiple UPSes at once longest power method so when the power goes out you have longer time to use the UPS
Would also recommend you guys mention Pure Sine vs Simulated Sine waves. From what I understand simulated sine UPS's are cheaper but may harm components such as screen back lights. Great weekly vids guys!
LTT should review a few ups i would like to know how actuate the volt amp ratings are and how good the software is
+1berkut the v/a readings arent really accurate and alot of them have crappy software... sadly...
@@kiskiller3 APC units will let you just hook up the "monitoring" USB even to Linux. Shows battery life, time and even let me have the option to shut her down should the battery runs on empty.

So glad you made a video on this!
Me watching this in a Blackout:
Thank you guys for this video
I have i7-4790K and use Line interactive UPS 600 watts capacity, which is only connected to PC. While a second setup i use is 900 watts inverters with modified sine wave current with 200 amps storage acid battery and i also use AVR with it, it is connected to whole system, monitor, pc, printer etc. I also have another big stablizer incase electricity start fluctuating too much.
Entire backup system costed me about, 400+ dollars.
Not bad
kevindt12 lolz, reason i commented if anyone wanted to know how to get proper off grid backup that lasts for hours.
AD KN I live in africa power cuts 4 - 6 times a week for long the normal setup here is 1500VA inverter with 9 x 12V 200AH barttery some people have here even way more VA inverters
I had pretty much same in first time. I used 200 amps battery with 900 watts inverter, also added AVR which gives pure sinewave current. But as soon as electricity goes out in rain, or heavy fluctuation, my PC got restarted. So i added another Line interactive UPS. Now it works fine.
AD KN Cool
I often hear that actual Pure Sine Wave (not simulated) is necessary for modern power supplies. Is this true?
+sircolby45 Yeah, I'm surprised this video didn't mention it at all. Some power supplies that emphasize power efficiency (especially 80 Plus certified ones) will depend on clean, consistent pure sine wave, instead of the approximate step kind. When I bought my UPS a few years ago, I was going to buy an APC brand unit that didn't have pure sine wave, and I found my PSU (Corsair TX650) has issues with non-PSW UPSes. I bought a CyberPower 1350PFCLCD instead and it's been fantastic. I even bought a second for my living room.
@@traviscombs6947 That's absurdly weird, even the cheapo non replaceable APC unit (it's was like 450VA or even less, rated for 255 max wattage) did just fine service for my Corsair 650 watts PSU and it is a bronze power supply.
Which UPS to buy? Thats easy. Buy the biggest UPS you can afford
It will keep your equipment running the longest.
!
I frequently listen to audio books while gaming. It's soothing to do while grinding.
Great video as always
Some UPS have the option of being powered and charge its batteries form solar panels. If your home have solar panels installed or you plan to dose you can use one of these with adequate capacity, and you may be able to pull part (all) of your home off grid, running (almost) entirely off solar power.
In a Nushell. A PowerBank/Battery Pack but with a Wall Outlet and a Step Up/Down converter and a Power Management
Not having a UPS at a critical moment can actually lead to brown shorts in a way...
+The Hoax Hotel tbh last time the power failed i was in the middle of studying online, so i kinda felt relieved lol
Surprised (and a little disappointed) that you didn't discuss the importance of "square sine", "simulated sine", and "pure sine" UPSes and what sort of equipment needs what quality of power.
Rule of thumb: Square sine should only be used for the most non-sensitive electronics. It's a very low-quality power that can damage whatever is connected to it. "Simulated Sine" should be used for computers, monitors, and LED, halogen, or fluorescent light bulbs. "Pure Sine" is for very sensitive equipment, such as speakers or audio interfaces, that absolutely need as close to real AC power as you can get it.
+Ben Hall Also there's the auto-engaged Diesel generator option, for the @3:31 4K gaming :-P
my APC UPS rates in watts, says max load is 865W with my desktop a 4790k/770/6drives/2monitor it gives me usually a estimated run time of 45minutes ,, been pretty dang good so far, i live in an area with tons black outs sometimes multiple in a day and alot of energy spikes, my apc has gotten through i'd say about 50 outages without a single issue
what model is it? been looking for something that lasts more than 15 minutes with those wattage
Rj Lao BR1500G+ but note my computer doesn't use even half its max watt at full use
We need an updated video reviewing this year (or last) best ups since pc gaming has been going up, specially this year.
Is power outages really that much of a problem in American/Canada?
TobyDK91 yes and no...
it is more like the old power lines we have aren't efficient as they could be/ storms knock them down, so the power goes out when you need it not to and when you least expect it, but it ultimately depends on where you live in the us/canada
@Chris Williams Makes sence. Your distances are quite large too.
Surprised there is no mention that power supplies with Active PFC require UPS's that output a pure sine wave.
Exactly. Pure sine wave UPSes are expensive.
Its measured in VA because it stands for apparent power and is all the power a battery can deliver. P stands for actual power, this is the power that is used to perform actual work. The difference between these two is caused by the fact the voltage not being in phase with the current this is caused by capacitive or inductive loads (not restive), the cosine of the angle between the voltage and current is called the power factor. P is calculated by voltage times amps times the powerfactor while S is calculated by voltage times amps. Therefore depending on the type of load the actual power to a device can be very different than the apparent power being used.
Me who uses a laptop: i’m just gonna use this for my laptop charger and my console
How often do i have to replace the UPS unit/battery? Every few years? Is it hard or expensive?
i wish you would have covered inverter types as well as whether modified/simulated sine wave inverters have any problems with 80+ PF corrected power supplies
Awesome graphics...!! Nice Work on that background...!!!
how many time that has happened to LMG?
+Parth Rastogi Never, they are people who live in a first world country and have to much spare money
i remember i had 3 blackouts out of no where in a row
managed to malfunction my motherboard and force me to seek salvaged parts to make the PC work again
so it can be useful depending on financial situation and how much you care about your devices
A UPS's voltage regulator will allow you to use old school or inexpensive generators. I used to work at a company that made UPS for mainframes and entire buildings. Best investment to protect electronics. Only big downside is the batteries need to be replaced every 2 to 4 years depending on the unit.
Well done !
*hits blunt* "duuuuude, what if you connect like 100 ups together? That's like unlimited power"

***** charge the battery first then wen max enjoy electricity for ever, give it as a gift for generations to come!
+Happy Farmer kenM
Thank you, very helpfull episode!
I wonder if they have in desktop tower UPS (PSU > UPS > Motherboard/components) because there are power losses from the battery charger going from ac to dc, then from the battery through the dc to ac inverter, and then again from the PSU when it converts the ac back to dc.
What about pure vs. simulated sine wave ups units?
Simply: pure is better.
Should it be "which" USP to buy?
You forgot to mention that this can also protect you against voltage spikes. But the power supplie already has a fuse and the primary and secondary sides are isolated each other so its almost impossible to damage parts like cpu gpu mobo ram...
DaUHardcoreCraft i lost my 2000$ pc becaus of voltage spikes
That was actually the first techquickie in a while that was interesting to me
I feel like the content quality has gone down a lot for a couple months otherwise
Ah, the one piece of tech that my setup needs that I don't have yet, the backup power supply. Most recently, before I built my current setup, we had a very temporary (>30min) blackout at around eleven PM and that shut down my PC. It had to do some odd startup sequence and restart during this multiple times for the computer itself to actually start up again, and a UPS would've allowed me to save and shut down my computer before I actually did something or, even, kept it running through the whole blackout so I wouldn't have a problem. Still, saving up for one is problematic... wanting to get into the PC-building arena isn't exactly cheap... and neither are apartments, come to think of it...
they did forgot to talk about on-line UPS and its difference with line interactive ones, as well as their compatibility with the PSUs, based on the waveform they produce
CyberPower CP1350AVR or 1500VA AVR
FTW
These have saved my computer from both brownouts and regulated strange pulsing wire voltage that damaged my previous computers. It even logs the events. 2 years going so far.
To be honest in my 40 years “up-time“ on this earth we only had one power-outage, and that was in the eighties.
Did luke just say "doing erin" in the audible advert?😂😂😂
LUKE, YOUR HAIR! I CANT CONCENTRATE WATCHING
Luke's hair is Slick.
I want to be able to run a presentation online for work without worry of a power blackout/brownout
Say I have a standard 120V household power line, and want to run my PC for 10 minutes. The PSU is 600w, monitor about 60 W and I want to keep my modem running. The PSU is sized mainly for my GPU. Also, what must stay running is my wireless headphones and my Scarlett 212 and Rode podmic. The PC I would imagine would be running on minimum power for running Powerpoint, Zoom and a few other apps.
What is the VA/W that I would need for a UPS? Thank you in advance
Me: man I really need one of these
Also me checking prices on Amazon: I guess I'll just keep unplugging my computer during thunderstorms 🥲
Waveform? I keep reading of certain power supplies needing UPSs that fully mimic outlet power for some reason. I have yet to have a PSU like that in the house. Still would have been nice to know if it is would be a good idea to buy that UPS type or not. As it seams to cost significantly more then the other model types.
"The Girl With All the Gifts" is a pretty awesome read. I have gotten to the action part and have to say it is just the kind of book that makes for great listening.
Doesn't do any good to have a decent UPS if the PC isn't set up right to take advantage of it. I am still not certain how to do that. I mostly just set the default Windows power features to force a shutdown while the battery still has a lot left in it. I am still remembering UPSs that would report a hour of run time to the computer and run out of power a minute after the power outage.
That thing about what wattage to shoot for will help. I tend to match them up and not go over.
I've got a 1500VA pure sine ups for my desktop, server, 2 monitors, printer, and modem. Can run all of them for about 45 minutes tops. Use to be longer but I think the batteries have gone capoopoo on me.
So what's a good recommendation for a 5830k + 980ti +raid + couple drive + 2monitor set up? Preferably with all the software saving options.
the ups works in the dark to serve the light
Actually, line-interactive UPSes kinda suck. If you want a high-end one, look for "double conversion." They are not as efficient because your gear is always on the inverter, but it avoids the imperfections in the sine wave when the UPS switches over. For business use, we saw a huge decrease in failed hard-drives when we made that change.
That said, line-interactive units are normally much less expansive than double conversion units.
It is not because the presence is resistance that causes wattage is not equal to volt times amp. In an ideal resistive load, P=VI. The reason we have VA product usually higher than real power is because the load ia not perfectly resistive. For an ideal resistor, the instantaneous current flowing through equals to the voltage applied instantaneously divided by resistance. Other loads are not. They have a lag between current and voltage, called phase angle. If voltage and current are completely 90 degrees shifted, no matter how much current or voltage, you do not have any real power. As the phase angle shifts from -90 to 90 degrees, your real load power goes from 0 to ideal, V*A, back to 0. In the second and third quadrant, your equipment will be sourcing power to the grid. Therefore, power supplies operate in quadrant 1 and 4, usually the current is a bit lagging. The cosine of the phase angle is called power factor, which is also the ratio between VA and P. In AC world, P=cos(theta)*V*I. Since most modern 80 plus power supplies has power factor correction units built in, the power factor is usually higher than 98%. So, the VA input will be almost the same as real power draw. The VA rating of an UPS is determined by its output stage's capability, and the P rating is determined by its battery to high voltage bus converter's capability. Be sure to consult the UPS's manual or an expert before choosing one.
Just get a UPS designed for loaded server racks. If we lost power at work, our UPS's would keep 6 servers running for up to 1 hour so for a home PC setup, you'd probably be able to carry on playing games until the power grid comes back online.
And where, pray tell are you going to put all those batteries? They're exactly cheap either and they weigh (literally) a tonne if you're talking that kind of backup potential.
I got a 1500VA Cyberpower UPS on sale, for just under $200. It gives me almost 30 minutes of run-time my rig is mid-range by today's standards. I'd say don't go lower than 1000VA in general to get half decent run-time.
650VA ones are not bad, you will easily get 15 minutes if you are on even a modern APU and a couple of 2.5" HDDs.
UPS i've had since 2008 just died, super sad - time to start shopping for a new one.
