Windows 7: Need Help Determining UPS VA/Watts

Need Help Determining UPS VA/Watts

I need help to determine the correct VA/watts I should be getting for my system. Here are my system specs:

i7 4770k OC to 4ghz.
Corsair AX760w PSU
Western Digital Caviar Black 2TB
EVGA GTX 770 Classified ACX 4GB
Asus Maximus VI Formula
Samsung Evo 840 1TB SSD
Kingston Beast Series 16GB 2400mhz OC to 2800mhz
Windows 8 64bit
Cooler Master CM Storm Stryker
Be Quiet Dark Rock Pro 2 Silentwings CPU cooler
Asus 23' LED 144hz Monitor

I was thinking of getting this, but wasn't sure if it was enough. Amazon.com : Cyberpower CP900AVR UPS - 900VA/560W AVR 8-Outlet RJ11/RJ45/Coax Tower EMI/RFI USB : Electronics I just need enough turn to time off my computer incase of a power outage.

I should say, you'll need at least a 1200VA/750W UPS to be confortable and protected from micro-power outage.

My local store recommended me that much for my own config with 700w PSU. Some says aswell to the set multiplier x1.5 the PSU wattage.

So for me it was at least for a 700w PSU x 1.5 => 1050VA (off-line model) + the components that will be used with, made that 1200VA/750W and should let me around 15mn to 20mn to save & turn off the PC if idle, when in game or full load it will be around 8mn.

So for the one from Amazon that I linked. Would it not give me enough time to even turn off the computer? What I'm saying is, if I use that one and there is a power outrage would my computer just turn off since there wouldn't be enough watts from the back up battery?

And my watt usage wouldn't be maxed out at 760w I don't think. Maybe around 450-550w during gaming?

900VA/560W UPS will give time to save and turn off, but the main problem is when too much components hardware are plugged in the UPS that could make it weaker.

1200VA/750W or 720W UPS could do it better to handle the load..

Let's say that if you're in game in case of power outage, 900VA might be quite limited. It could handle it if when power outage when PC idle.

Oh okay, I understand what you are getting at now. I guess something like this should be more than sufficient: http://www.amazon.ca/CyberPower-CP13...s=CP1350AVRLCD

Yes, could be the one you need!

and this one either: Cyberpower CP1200AVR UPS - 1200VA/720W AVR 8-Outlet RJ11/RJ45/Coax Tower EMI/RFI USB/Serial, (a little cheaper on price).

I cheated. Instead of trying to figure out how much I needed, I just got the biggest one I could find (I did wait until it went on sale). With my computer and monitor plugged in and running, it has 116 minutes of runtime. I have it set to hibernate my computer five minutes after a power outage. Since it takes 24 hours to recharge the batteries if they are fully discharged, that ensures sufficient power will be left in case of multiple power outages in a day (such as we had off and on for a couple of weeks or so last summer before the problem was finally tracked down).

That's smart but also quite expensive solution...those damn UPS are not that cheaper, i recon!

The most i'll afford will be for a 1600VA which is far enough for me.
