I currently have a Corsair CX750M psu, and am expecting a new GPU in the mail today that requires one 8pin and one 6pin power connector. I have open the correct 6+2 PCIE port, but I'm not sure if I put the 6pin in a peripheral and sata port or the 4+4 cpu port. I'm assuming that since it's a peripheral and not a cpu that it goes in the peripheral port, but just want to make sure before I go plugging things in.
