I am getting this PSU and this video card. The card requires 12V current rating of 20A or more and the power supply has +3.3V@32A, +5V@35A, +12V1@17A, +12V2@19A, -12V@0.3A, +5VSB@2A. Should the +12V2@19A be fine, or will I get problems? They are both SLi ready, so I assumed they should be fine. Anyone know?
 
For the single card you should be fine since the combined +12v is ~36A

If you plan to upgrade to SLI, well I am not so sure anymore, since I came across a couple of articles at Bjorn3d and Extremetech where in both cases a dual-rail PS just didn't cut it.

But maybe it is just an issue w/ the 7800GTX in SLI or X1800XT/X1900XT in crossfire mode paired with a dual-rail ps performance was bad, and a single rail or a 3+ 12v rail PS did work well... in either case it is worth a read.
