Well at first I had.
GPU 2x 6+2 pins
Sound from psu a splitter 1 x 2 6+2 pins (which makes no sense at all)
Now:
Gpu: 1 x 6+2 and the splitter thing
sound 1 x 6+2
It came with my psu. It gave way to much juice.
So i currently use a single PCI cable that is shorter. And doesnt give it to much juice. I will make a picture. sec
