That may seem obvious, but here's an example: my G34 4X6136 draws just under 600W under Folding. That's without an overclock (not yet, at least ) and only one hard drive.
Any 650 or great Watt psu will do.
When just sitting on a bench my 4 x 6174 takes up 520w.
When in a case with fans at 4400 RPMs my 4 x 6128s take up 500w.
A 1000w unit is ideal, you are right a 750w-850w is what to shoot for, but I think when on a budget 650w is is just fine. Of course, you want a psu with a rated wattage at double you pc's because psu's wattage pulled at the wall is a bell cure.
I recommended the 650w because he is on a budget, going for some 8 core chips (w/o an OC) and because the price goes up quite quickly with gold standard PSUs.
Alright, a picture of my updated setup. The board in the middle is my only tyan, and is the only one not currently folding. The SM on the right is running the 6128s now, on Wed my 6134s come in, and then the 6128s will go to the tyan. Once all the chips are in, I will be all set and will get the 6174s and 6134s overclocked.
