your link clearly states that a 750w PSU is required.

you can use any of these online power supply calculators:

You can get away with less than the 'required' PSU level, but I'd say you need a QUALITY 550W PSU at the least. I can't recommend you running it on your current 500W. 750W is plenty, but 850W may be worthwhile if you're upgrading and maybe getting 2x graphics cards in the future.

How will your onboard video handle it?
  • The specifics depend on which onboard adaptor it exactly is.
  • You need to check BIOS and confirm that 'prefer PCIe graphics' is checked.
  • You can usually leave both running, or just disable onboard in Device Manager. Sometimes motherboards can take advantage of both onboard AND dedicated, for performance boost. See: Lucid Logic MVP

Well, what power supply do you have?
Rosewill Capstone 450 will fine, along with some other high quality 400w-500w power supplies.
