Now for a baby Maxwell - MSI Twin Frozr Gaming GTX 750 Ti OC that only uses 60 watts. My whole PC only uses a little over 150 watts at AC wall outlet (Kill A Watt meter). On bumped up overclock settings temperature peaks at 53 C with quiet fans automatically bumping up 2% to 34% max.

Since my system only used about 206 watts max AC input with 116 watt GTX 550 Ti without any issues I am tempted to try a GTX 970 (145 watts) to see if that would work with my existing system without having to bump up my PSU. It is a Dell XPS 8100 that I think has a conservatively rated 350 watt PSU, but Dell never mentioned its PSU rating in spec's (originally just had GT 220 video).
