Hello, I need a 600+ watt power supply for crossfiring Asus DirectCU Radeon HD 5850's. I would also like to voltage tweak them and overclock, in addition to overclocking my Phenom II X4 965 CPU and G.Skill Ripjaw 2GBx2 RAM. How many watts would be sufficient for my setup? Also what other factors are there to consider? Please make some recommendations that you feel are best for my build. My case is the Cooler Master HAF 932.
This is the one I have http://www.newegg.com/Product/Product.aspx?Item=N82E168... not that I needed this much power for what I run but its what the store had. Its very good and should run you just fine.
other than that hit newegg up and go advanced search on power supplies and under SLI type select crossfire ready or certified. You definitely want 750w+ imo.
