I'm currently using a Thermaltake 420watt supply for my asus a8n-sli deluxe. My computer keeps resetting every so often when i play games for a while. What kind of supply do you guys reccommend and how can i tell the difference between a regular atx supply and a 24 pin atx supply? I'm looking into purchasing a 24pin atx supply but i'm not sure exactly what they are called. I'm running 2gigs of ddr3200 ram, xfx6800ultra, and a amd 3500 cpu.
