Speaking of using 2 Titan-Xs, which a few of you are, what kind of PSU do you need to run 2 of those which require 250w of power each? Is an 850w unit going to cover all that & be stable, or not?

 

The Titan-X has 12Gb of RAM by itself. My main RAM is 16Gb with a quadcore 3.7Ghz I7 proc and 3 HDDs. I may soon replace my C drive with an SSD.
