My budget is about $125. It's going to eventually be running a 5820k and a pair of Sapphire Vapor X 7970s. I'll have about 6-8 hard drives and an ssd. I was looking at PSUs in the 850W range that are fully modular. I found a rosewill I liked but I don't know enough about other brands to make a decision. SeaSonic would be my first choice it the fund were available.
