SLI EVGA GTX 680 + i7 PSU Suggestions


So i am putting together a new machine and am trying to determine the best PSU to go with for this setup. I heard this was a great place to get feedback from people who know more than i do. So here is the build i am thinking about

Processor Intel Core i7-3770K Ivy Bridge 3.5GHz
Motherboard ASRock Z77 Professional
Graphics Card (2 SLI) EVGA 02G-P4-2680-KR
Sound Card HT | OMEGA eClaro 7.1
Fan/Heat Sync ZALMAN CNPS9500A-LED
RAM G.SKILL Ripjaws X Series 32GB (4 x 8GB)
SSD Of some Sort

So my guess is that i need a 750 -1000W PSU, but which brand.... how much, etc --- really in the woods.
