UPS wattage for my pc

[Guillermofletes]

I was wondering how much wattage and VA for my UPS i should get for my gaming pc that takes up about 400w. If you have a specific UPS that you recommend me please feel free to include that. Thank you

I am not going to recommend any UPSes, but I will help you understand the theory.
VA is the same as watts -> Watts = Voltage * current
As with computer power supplies, you do not want to skimp on this, as the power supply can overheat or shuts down.
Same with a UPS. Overspeccing it is a good idea as you know it will perform for a long time and will not shut down due to heat. Considering you computer takes about 400w, it seems sensible to have a UPS rated at 500w or higher to gaurantee that no matter what you are doing, the UPS will handle it.

Does your system have a power supply unit that has APFC and requires a pure sinewave UPS?

Is the monitor going to be plugged into the battery backup side of the UPS?

How much battery backup runtime do you want?

Here is my power supply http://www.newegg.com/Product/Product.aspx?item=N82E16817438054

and i will only have my monitor connected to it too

i want at least a couple minutes enough for me to turn off my pc

That EVGA SuperNOVA 650 G2 power supply unit has APFC (Active Power Factor Correction). For guaranteed UPS compatibility you'll want to get a pure sinewave UPS.

1000VA or greater should be what you're looking for. If more than one power interruption happens in a short period of time you're better off going with a 1350VA or greater because the battery recharge time may be 8 hours to bring the batteries back up to full charge from their discharged state.

so the 1000VA is barley enough or more than enough?

here is my pc build just to be exact. My future pc uses 332w estimated just to be exact.

also wouldn't i need a UPS with 650w or more since my pc PSU is 650w please explain why or why not? (my pc will prob only be taking up less than 400w)

If your PSU is rated at 650W, then it is theoretically capable of outputting a steady 650W (cheaper PSU's not so much). But if your components only "demand" 400W, that is what the PSU will provide.

so will this UPS be good for me?

 

[mjslakeridge]

That looks like it will suit your needs. According the the charts provided above it will give you 5-6 minutes to shut down if your components are drawing about 400W. Don't forget to look at how many Watts your monitor draws, this should be shown where the power cord goes into the monitor, or check the monitor makers website. Most modern monitors draw very little current, probably less than 20W, unlike the old CRT monitors.

Yes, that's the minimum you should be considering.

What's the brand and model of the monitor/display? This is to get an idea of how much power the monitor/display is going to be drawing.

Here is my monitor https://www.amazon.com/BenQ-XL2720Z-Gaming-Monitor-Resolution/dp/B00GWFNMJS ive read that it takes up about 25w or 32w max

Then you should be good with the UPS you referred to above.

BenQ's specs say that it's 27 Watts. That CP1000PFCLCD UPS should be fine.

One other thing to consider with UPS is that over time the lead-acid batteries get weaker and won't hold a charge for as long (just like the battery in your car), so it's backup power time will decrease. You can replace the battery(s) in the UPS. That looks like a pretty good UPS and should tell you the health of the battery. I had one where the battery went completely dead (and acid leaked out due to a malfunction in the charging circuit), yet the battery warning led on the front panel never came on.

It is not a bad idea, from time to time, to test the UPS by unplugging it from the wall and see how long it continues to power your computer/monitor (not while working on anything important, of course).
