Concerned about power requirements

[Dra]

So I've got all my parts for my i7 build in, and now I'm thinking my HX620 will not be enough (I haven't put it together yet, as I am out of town for the week).

Here are the parts

i7 920
Asus P6T
6GB Corsair Dominator
GTX 280 SSC
WD6400AAKS
Samsung DVD-RW

I'm looking to OC the 920 between 3.2 and 3.4 Ghz. Will the 620 be enough, or is it pushing it?

It will be enough. If you plan on adding a second video card in the future however, you will need to upgrade it.

agreed, definitely enough but another gtx 280 would kill it lol
