-->3GB DDR3 CORSAIR 1333MHZ
-->EVGA GTX 275 896 MB DDR3

What make/model power supply are you using?

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:

Read at least UPS Ratings, Other caveats.
