Correct UPS/Battery Backup Size for Computer

[sjf999]

Looking at buying APC BE600M1 UPS/Battery Backup. I have a 600w psu, running average graphics card, 2 hard drives, 2 optical drives. I read conflicting information about whether the UPS can handle my PC, any advice? Thanks in advance.

600w psu does not tell us your actual draw.

you could estimate by using a psu calc site to get a rough idea. keep in mind that idle power usage is much less than gaming usage.

you can use this chart http://www.apc.com/products/runtime_for_extendedruntime.cfm?upsfamily=27 along with your estimates (i'm thinking likely in the 400-500w range under load) to come up with a runtime.

i would say the 330w/500va is undersized for your needs unless you have under 300w draw.

i use a 780w/1300va model for my system with an older i7 and gtx770. i can get about 10 minutes of runtime at idle or 3 or 4 at load.
