A few of the Corsair PSU's give current draw readings. My board uses only 12V supply so can get some measurements without graphic card for different CPU loads then take those loads away when using the graphics card to get graphics power draw. Measurement of GPU power from HWiNFO info ties in very close to these 12V power rail measurements on my Galax FE so seem to be pretty good unless of course one uses a hard mod or software mod then only 12V rail current draw will show the real draw.
Best to use the graph in HWiNFO rather than max reading to get a better idea of what's going on though IMO.Edited by ucode - 8/14/16 at 7:17am
