Hey, so I've recently built a PC with some help, however I keep getting the error in the title when booting up. I have an 8pin plugged into the GPU and the other end being 6+2 into the PSU. (PSU is the Corsair CX750M) I've reseated the card many times, and tried many other things and am at a complete loss.
Also, It will boot up when I just plug into the MOBO.
