I'm looking to buy one, specifically this one and my current PSU can output 23 Amps on the 12V1 rail, and 20 Amps on the 12V2 rail. Is this enough power to juice the graphics card? I have a 600W PSU, btw. And if it can't should I just wait 'til the GTX 1050 comes out? (Assuming that'll consume less power)
