What about the power requirements? Second PSU required or would an 8 to 6 pin adapter be safe with this GPU at 100% load?
Edit: Answered my question after checking some reviews. Looks like the card pulls 250 to 270 watts under load, and in every case required significantly more than the 680 and 580. And no, those are not system loads, but are apparently pretty good efforts to sift out other variables and get an accurate bead on the GPU power consumption. Titans pull every watt of the rated 250 when pushed to the max. With all the talk of burning up mobo components it doesn't look like it would be safe at all without additional power.
