I just bought parts to build my very first pc and I am confused on the cables to use from my psu. I got a psu Seasonic M12II “Bronze” Series 620W that has 8pins for its PCI-e/CPU. It came with two cables with an 8pin PSU and two 6+2pins PCI-e on the other side. And I have a Gigabyte GTX 970 G1 Gaming that requires a 6pin, 8pin PCI-e. Is it ok to use only one of these cables to power my GPU?
