Can my psu handle a second 480?

post #1 of 3
Thread Starter 
I'd like to get one for christmas or later to completely finalize this build as I never experienced SLI before and I'm really excited at how good the 480's scale now, but I've given about 60% varying feedback on if the x-750 can handle it.

Seasonic is a great PSU brand and Hodgoes2001 runs 2x480's at 800 core on a TX750 just fine. Most on this board will say you need an 850, some will say you need 1k'ish. Since you already have the 750 I say toss the second 480 in and let 'em run.
