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.

[@kaesden]

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.

@@obiokeke9963 A little late but here we go: PC power supply has Active PFC (whatever that means, I'm not gonna look it up right now) If you have a power supply like that, you need a pure-sine UPS Low end UPS's will have stepped output (or in the worst case I've seen square wave outputs before) and these will case the computer to cut out on battery power (rendering the UPS obsolete) Get a UPS that is stated to be compatible with active PFC.

THANK YOU for putting this video together in all the right ways.

[@jrsmithunited]

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.

[@amahashadow]

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)

[@kiskiller3]

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..

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)

[@Fish_nipples1998]

The tip about the food in your fridge is definitely a great point to make. It's one thing to expect normal power outages from anywhere from like a minute to an hour or two. But if your power outage lasts for multiple hours on end my suggestion would be to not open the fridge or at least not open it anymore than you have to in order to preserve coldness for as long as you can. It happened to me twice now where the power has been out for more than 16 hours and fridges all though they are insulated aren't designed to hold temperature for very long. Though there was a lot of food I could save, there's also a lot of food I had to throw out after the power came back on. I would definitely recommend a UPS and quite frankly I've actually bought one that cost me almost $8,000 but it covers what I consider "essential things." It'll keep my fridge running for an extra half hour(or an hour if that's all I have plugged in.) But I also have a lot of smaller ones around the house for my computer. And I actually have one that I paid about 800 bucks for just so I can use an LED lamp in the event that it ever happens again just so I have light. Off the grid with the LED light (and possibly my phone charging) for about three and a half to four hours. The other thing I did was buy a gas powered generator which of course is less useful for a PC but can be used to charged a UPS. IF ABSOLUTELY NEEDED. As well as a couple other things. I would recommend having power backup of one form or another that's adequate for your bare minimum needs. And I would consider bare minimum far below your everyday standard because in the event that you have to use it you're not going to be in normal circumstances.

[@Fish_nipples1998]

That being said if you can afford gas and you have a place to put it it might be useful just to have a gas powered generator as well as a UPS that suits your needs. Because as long as you have gas and keep it maintain ed the gas generator can power anywhere from a couple to many different things. The diesel generator I have at my work can power about a block's worth of houses. Although It only powers the building that I work in because my building has such a high power usage. (Medical building with end of life care.) That's where I got the idea to have both the UPS and the gas powered generator. UPS for my computer and my fridge. But the fact that you can use the gas power generator to power the UPS actually works out really well. And theoretically as long as my IPS can maintain an internet connection then I can power my router and my computer or my phone off of either my UPS or my gas generator. just things to consider obviously if you have the money for one or both of them.If you're going for more of a survival type thinking I would consider the gas generator and buy gas. However if you're used to more like rolling blackouts (especially in large cities.) than I would suggest the UPS it'll give you enough time to save your stuff or even protect your stuff without you losing data or your progress like he said. Quite frankly if you have something like a desktop where you rely solely on wall power I would buy a UPS anyway just to protect it. I found them as cheap as 50 maybe 60 bucks. And It will work for most PCs long enough just to stop or save your work and shut down your computer properly.

@@varunthapliyal8960 There are line-interactive UPS models with pure sinewave output as well.

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.

[@network_king]

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.

[@Jez2008UK]

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.

[@ghffrsfygdhfjkjiysdz]

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.

[@bardawulf5827]

+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.

[@ghffrsfygdhfjkjiysdz]

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.

[@o_o6869]

this is always a must have piece of tech in my home for sure no joke

[@behemothinferno]

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.

[@Chr0nalis]

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.

[@fliprabbit]

yes it is

[@Fantasma25]

+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

[@miinyoo]

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.

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.

[@sandermans15]

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.

[@DriftHyena]

[@John-uj9zy]

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.

[@CorpusOrganic]

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.

Have an APC Smart-UPS 1500 that backs up the I-5 Desktop Computer, 1080P Monitor, Dell 24-Port Switch and the CenturyLink ADSL Modm. This keeps me up and running when the lights flicker and the clocks need to be reset ! And if the outage lasts a few minutes I will have time to shut down ! tjl

[@D8W2P4]

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.

[@Kirbythediver]

Just used a "killawatt" meter on each device at a time to calculate before i buy a UPS. Now i've got to decode how UPS wattage works

[@GiancarloDiamond]

loved this happened 2 nights ago in Bucharest i hate outages as i have expensive computer and other devices :(

[@matthewsmeets]

Did luke just say "doing erin" in the audible advert?😂😂😂

[@RomainCavallini]

i'm skeptical about volt amps, the difference between VA and Watts is the cos phi, the image of dephasing between voltage and current consumption, also named power factor(if the load is purely resistive your cos phi will be 1, if its inductive or capacitive, it will go down, and its not good at all) all modern power power supplies have a PFC corrector, which mean your cosphi is almost at 1, and, in this scenario, VA=W

[@Skyguy1193]

also true sine wave for active pfc power supplies

[@yumri4]

RS-232 is more common than USB for most of the higher end ones as pin testing is easier to work with. As serial ports are no longer common. SIIG which makes PCIe x1 to external serial port 1 and 2 port external port cards.Likes RS-232 being used. I do not see this going away soon either. For end users it is hard as usb is on basically everything now but most end-users don't use UPS units until their power is cut for a long time very often.

[@marioskatsigiannis3047]

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

[@aaaugggghhh]

I was on KZbin until late the notification that this video had been uploaded. then I was like, "1st view? challenge accepted!" then I went on the video and it already was over 1000views.

[@micnor14]

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.

[@spaghettigod43]

[@halofannatic]

Buying a UPS has honestly been the single best purchase for my computer system I've ever made. Hands down.

[@Jez2008UK]

Why? did it cut in on a power outage? Or is it the peace of mind it give you?

[@adkn]

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.

[@kevindt100]

Not bad

[@adkn]

kevindt12 lolz, reason i commented if anyone wanted to know how to get proper off grid backup that lasts for hours.

[@kevindt100]

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

[@adkn]

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.

[@kevindt100]

AD KN Cool

[@nccish]

I frequently listen to audio books while gaming. It's soothing to do while grinding.

[@enfission]

Surprised there is no mention that power supplies with Active PFC require UPS's that output a pure sine wave.

[@kenvme]

Exactly. Pure sine wave UPSes are expensive.

[@1berkut]

LTT should review a few ups i would like to know how actuate the volt amp ratings are and how good the software is

[@kiskiller3]

+1berkut the v/a readings arent really accurate and alot of them have crappy software... sadly...

[@rickytorres9089]

@@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.

[@KerenWang]

So what's a good recommendation for a 5830k + 980ti +raid + couple drive + 2monitor set up? Preferably with all the software saving options.

Oh, I thought this was about the UPS delivery.

[@dominicbeaudoin2762]

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

[@FezCaliph]

@@dominicbeaudoin2762 never had a problem with them.

[@CDNSpartan]

I remember a few years ago before I got my PC I was playing a game on my Xbox 360 about to shoot at someone as the game was Just Cause 2 and then the power went out.

[@UnderwearThief]

Volt-Amps are what is known as "apparent power" or V*I. Watts are known as "real power," or apparent power multiplied by the power factor, which is the cosine of the phase of the voltage minus the phase of the current. The more you know.

[@marcse7en]

Se7enQuickie: In 27 years of using and building computers, I have NEVER lost data due to a power outage! ... And I have NEVER felt the need for a UPS! ... In the UK, our power grid is extremely reliable, and our AC outlets are far superior to your God awful US electrics! ... If one uses a laptop, a UPS isn't necessary, as the machine switches to battery in an outage ... The most important thing to remember, is SAVE, SAVE, SAVE! ... Glad I could help! 👍🤣

[@TheMrMKultra]

good thing i only use my laptop. also saving your documents every now and then helps with not losing much data

[@xodius80]

Loop the cable that goes to the wall to the ups and there u get etrenal electricity, you are welcome.

[@Starfals]

How often do i have to replace the UPS unit/battery? Every few years? Is it hard or expensive?

[@themooq]

To be honest in my 40 years “up-time“ on this earth we only had one power-outage, and that was in the eighties.

[@bskull3232]

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.

[@qua7771]

I'm considering one for home theater given that power conditioners coat almost as much. I need 3,000 watts of clean power for a 7.2.4 set up.
