Would this APC work well with my power supply?

I'm considering buying this backup power unit to power my desktop PC and monitor, maybe my ps3 as well, long enough to shut them down if there is a blackout of the AC blows the power fuse during a hot day. I also heard it helps the health of the PC in general.

Would this

I'm not well versed in electricity, so when they started measuring in "VA"s, whatever those are, I figured I should come ask you guys

The specs on the amazon link show it has a 330 watt output capacity. Since that power supply is 650 watts and you need to power your monitor and maybe PS3 you would need a larger battery backup for it to run your system.
