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..

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.

Works very well on APC units apparently. So useful!

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)

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.

Thank you!! Not many tech channels talk about this very much. :)

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

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

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.

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

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.

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.

I'm looking into a lithium ion UPS for fast charge times. My lead acids are starting to wear out.

Which UPS to buy? Thats easy. Buy the biggest UPS you can afford It will keep your equipment running the longest. !

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.

This was a poorly covered video. First the image of power surges, and talking about UPS is not a very good thing. If you plug in a power surge protector into a UPS you can severly damage your equipment. Look it up. Next you have covered Sinewaves before, but if you are giving a "What to buy UPS" then it's critical to mention the sinewaves...

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.

+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.

so if my pc uses a maximum of 470w, i have a 650w psu, how many va should i get?

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.

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: man I really need one of these Also me checking prices on Amazon: I guess I'll just keep unplugging my computer during thunderstorms 🥲

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.

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.

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.

For AC a Volt Amp is NOT a Watt! P = IE cos θ Where θ is the phase angle between the current and the voltage. If the load is purely resistive, as is the case for DC, then θ = 0 and cos θ = 1 For purely inductive or capacitive loads θ will be either +90 or -90 and cos θ = 0, meaning Watts = 0, but volt amps will not be 0.

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.

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

If you have the money then I would also recommend on-line UPSs which differ from line-interactive devices. They are more pricey but offer better performance.

Hey as long as it doesn't dips it doesn't matters lol. Even my cheapo 450VA APC unit did just fine when I unplugged the unit.

Been using UPS' 16 years or so, can't imagine being without them. 1500VA for demanding bunch of stuff and 650VA for less demanding bunch of stuff such as floor lamp (2 hours of LED lighting on battery, hell yeah). 1500VA is connected to the NAS and PCs use NUT client to connect to the NUT daemon on the NAS. Everything shuts down automatically when the battery goes critical.

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.

how many time that has happened to LMG?

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.

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.

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

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.

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

Yeah, but do I need to pay up for the better brands or will any cheap UPS be good enough? I mean the price difference for same VA UPSs can be HUGE. Will the cheapest one save my motherboard from dying in a brown-out just the same?

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

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.

i live in a area with spotty power so buying a UPS was a must when i got my new computer

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

A UPS is like a fire extinguisher; you really want to have one on hand, but you hope it never becomes necessary.

How about doing a bios update. Which would be recommended for a ups? I’m not trying to spend $200 unless it’s necessary don’t really care if my work gets loss but if my motherboard breaks then that’s a big ass deal

What about pure vs. simulated sine wave ups units?

@kenkalajdzic

Simply: pure is better.

Your volt-amps explaination is wrong. Volt-amps is a measure of apparent power which is a mix of real power (watts) and reactive power (var). Naturally in all practical ac appliances volt-amps are higher than watts because reactive power is almost always present. PSU have a very good power factor (watts/VA) which is a ration of watts to volt amps. That means that his Volt-amps rating is very close to his watts rating which also means that they are design to consume very little reactive power. So that 50% to 75% number you gave is very steep imo.

+octavio echeverria exactly, if you are not connecting a big ass AC motor to your UPS, the VAr will be quite low

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'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

Me who uses a laptop: i’m just gonna use this for my laptop charger and my console

So how do I calculate the amount of power that I have uses? As you can tell, I'm just an end-user! I have a modem, monitor, signal booster (for cell), the main computer (desktop with be quiet! SYSTEM POWER U9 500W BRONZE), and cordless phone base. I have a UPS APC-ES750 and replacement batteries never get past 8 months before I need a new one.

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'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.

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.

your avg 550va upc from either apc or cyber power should world for 80+% of people if you have a brain enough to turn off your pc ASAP, sometimes that means loosing time since the last game save, but i has given me around 5 mintutes on an amd 8350 and r9 290 with 2 monitors at full blast, which is by far enough to shut down properly. it's also helps on those small brown outs that cause voltage drops that psu's may hot have enough hold up time for.

How important is that "VA" though, because 500VA is about 300Watts. If I have a computer with a 500Watt Power supply does that mean I shouldn't use that computer with that UPS?

Should it be "which" USP to buy?
