I'm running the system in my signature and even in GTA 4, BF3, or Metro 2033 maxed out it's only pulling 650watts maybe 675 from the wall. 1000Watts would be perfectly fine and would give you room if you used it in your next build. That was my logic behind it. I wanted to keep the PSU for my next build.

The rig builder is a total pain to use, but basically:
2600k
Dual MSI 580 3gb Xtremes
5 7200rpm harddrives
Single SSD
4x4gb ram
Loads of fans

1000watts is plenty for it.
