Hello everyone

I would like to get a new UPS for my PC, but i want to know the capacity (VA/Watts) that it should have considering the parts that I have:

-->Core i7 920 Turbo mode ON 2.8 GHz
-->EVGA X58 SLI LE MOBO
-->3GB DDR3 CORSAIR 1333MHZ
-->EVGA GTX 275 896 MB DDR3
-->250 GB Sata Samsung HDD
-->1TB Sata Samsung HDD
-->Antec 900 with 5 active fans
-->32 inch LCD TV 720P LG


Any help would be appreciated......
 
Anyhow, assuming you are using a 750W power supply with an 80% efficiency, it can draw a maximum of 937.5W from the wall. Add another 112.5 for your monitor (its average draw is 106W), and you get 1050W. So, in theory you need a UPS that can deliver 1050W. That's a BIG UPS.

Assume you are actually using 600W max inside the PC, that would be 750W at the wall. You could use this UPS for the tower:

And a small one like this for the monitor:
