Hey,
My PSU is 460 watt cooler master. I think I should be fine with the watts as Nvidia recommends 450 watt for GTX 660 and the newegg calculator shows the power draw of the PC to be around 415 watts.
However, what concerns me are the rails. The minimum requirement is 12V/24A. I have 2 12V/18A rails. So can I run the card using these 2 rails?

I wouldn't recommend using a Cooler Master PSU period. They're a bit of an infamous name, to be honest. I would suggest replacing it with the drastically more reliable XFX Core Editon 550w, which is presently $45 with rebate at NCIX US: http://us.ncix.com/products/?usaffiliateid=1000031504&s...


jack is right, the XFX 550w is efficient, small, reliable, good price, and has a 5 year warranty from XFX.

Hello,

I brought a Corsair CX 750w Build series psu when I got the same GPU. Never had a issue and works like a charm. Also leaves some room for expansion as I was tempted not long after to buy another and run them SLI
