I am going to use my old 4870 on this for now I can't find the link for it.
I was going to use my 550W PSU but the day before I got the parts at my house it went out. I was wondering what PSU will fit ALL of these? I would want to drive up to WalMart, Frys, and/or MicroCenter as I wanted to build my computer today and don't want to wait for the shipping.
Antec, Corsair or Seasonic in the 500-550 watt range would be plenty for the system! See what is available at the store. By the way you have a triple channel ram kit for a dual channel board!
^+1 better efficiency, Great company, and probably cheaper with the free shipping. And I believe you should go with some dual channel memory, it will probably run better if you populate the right slots.
