Is my PSU powerful enough for a single 680 GTX [Pic Enclosed]

I have 48 amps on my 12v Rail.

I don't think that will work well. I would recommend at least a 650W PSU for a GTX 680.

But don't I have 48 amps (adding all the 12v #'s)? Enough for a a 680 @ 38 Amps?

The max amps for all rails together is not figured by just adding the max amps for each rail individually. To find that, you divide the 408W total for all 12V rails by 12. 408 watts/12= 34 total amps.

Less than minimum, I really wouldn't risk it.
