I would think so, but Rosewill is not known for there good PSUs. I do know that that Rosewill PSU will not supply 600w. I would get this: http://www.newegg.com/Product/Product.aspx?Item=N82E168... It's enough to CF two hd6950s. The reason I say to get that is because any other PSU that would run it well would cost around the same, and give you barely enough power. If you get that PSU, you will have a lot more power than the others around that price range, for a few more bucks.
