GTX 560 Ti power requirements

Hello,

I currently have this system :

AMD Athlon II X4 635 (stock voltage overclock) 3,4Ghz
Gigabyte MA78G-DS3HP
2x2GB DDR2 800 Crucial Ballistix
Seagate 250gb 7200rpm 16mb cache
Coolermaster eXtreme Power Plus 650W

I am planning to buy a GTX 560 Ti. Will my power supply be good enough to handle it?
I'm pretty sure it has enough watts, but I don't know about the amps :??:
I read somewhere the card needs about 30A (I might be wrong) and my PSU has two 12V rails with 18A each.
Oh, and I have it since 3 years.

  1. Hi, the 560 ti is an awesome card. You will only need 500w for your entire system. If you feel comfortable wanting more than I would go with 550W.

    Cooler Master actually doesn't make good power supply. It will be able to handle your setup though: http://www.overclock.net/power-supplies/642102-cooler-master-extreme-power-plus-650w.html

    You have plenty of PSU for the job.

    A few years back Cooler Master was putting their name on some crappy PSUs... The current stock seems to be of better quality but your PSU is 3 years old and falls into the time period when Cooler Master was not as reliable. I'd be a bit worried about a PSU failure
