Depends on what the specs of your power supply are. You need to know the Amps or Watts on the +12v Rail/s

Let me know if you get any results. I will be doing a similar process with a 4770 with a 350 w PSU with a quad processor and 4 gb ram. So if you test it out I would love to know what happened. If you dont I will let you know what I find out when I install it within the next month.
