I have the GIGABYTE GA-Z68AP-D3 motherboard and a Corsair CX600 PSU, and I cant seem to figure out which cable to plug into ATX12V (4 pins). Theres an 8 pin cable which has 4 pins that would fit into it, im just not sure if thats the cable.
usually transparently white as the color of power connector, 8pins separated into 4pins x 2.
The other 6pins probably separated into 4pins x1 + 2pins x 1 mostly for peripheral device such as vga card.
They are error-proof designed.
