Graphic cards and power supply

I'm going to upgrade my graphics card from a gtx 550 ti to a gtx 570. I've read that the 570 requires at least a 500w power supply. I have a 750w. Can anyone tell me if that would be sufficent given the amount of power the other components of my computer draw? Thanks so much for any help!

(I am currently running)

Win 7
Intel i5 2500k
gtx 550 ti
8 gig RAM

  1. A quality 750 is plenty for GTX570
  2. If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.
