wylliexhan good question^^ that i do not know since i don't own nor have the right tools(here) to check the total power consumption directly to the wall.
but when i was in SG, using a different cpu (intel 4820k), board(Asus Rampage IV), ram(4x4GB Dominator 2400) and psu(seasonic 1200w platinum).
entire setup with the crossfire tri-x gpu, power draw is around 750w++(full load), 2ssd, 2hdds and a few non-led fans.
I haven't been able to test the entire setup since this card is 2.2 pcie and when the tri-x fans runs at full speed, it hits the bottom gpu.
currently using 1 gpu. 1 card takes about 300w at full load.
Up for tonight.
