Is it ok to use this video card with this power supply?

Hello, so I got an EVGA GeForce GTX 560 Ti Superclocked for Christmas, and I figured I would have had a good enough Power Supply to use it, but according to the manual I need 2 30A 12V rails.

Currently I have a 500 watt PSU with 2 18A 12V rails. So my question is, is it ok to use this card with my current PSU? If I need to buy a new one, would it be ok to use it now and buy a new PSU later? Like in a couple of days


Edit: On the side of my PSU it has a chart, the 12v1 and 12v2 both have 18A, with a max of 432 Watts. If that makes any difference

  1. Well first of all the GTX 560 TI needs one 12V rail at 30A. You didn't mention the manufacturer and model of your current power supply, so I can't say if it's a good or bad Power Supply.

    GTX 560 Ti needs:
    2 x PCI-e PSU Connectors
    12V rail at minimum of 30A

    I'd suggest a good 600W Power Supply. Like the Corsair GS600
    It has a single 12V rail at 48A: $90 at Newegg
  2. Rocketfish 500 Watt RF-500WPS2

    Thanks for the recommendation. I'll check it out
