  1. I'd park it in the 850w+ range for a good PSU brand with at least 60a on the 12v rail. Make sure you have a PSU with the proper conncectors. Manufacture spec is for a 1kw unit. Use the link for PSU in my sig and you can see a list of the reviewed PSUs and how they stack up to each other. Interesting GPU selection.
  2. Count up the total number of pci-e 6 or 8 pin power connectors that your graphics configuration needs.
    Get a psu with that number of leads. All your other parts are normal, and accounted for.

    A quality PSU will be able to deliver enough power for all the leads at any load and temperature.

    Quality units come from Corsair, PC P&C, Seasonic, Antec to name a few.

    Your requirements will be satisfied typically by a 750w unit.
  3. Thanks guys for all the help.


    Thanks a Bunch. I will try the links and also check out some of the suggested PSU's.
