I am installing a new graphics card in my computer (HD Radeon 6950: Power Color Series) and on the top right end of the card there are two different sets of pins for a power cords to go into. The first one is 8 pins and the other is 6.
My old one only had two 6 pin power ports (or whatever you call them?). I have two "power cords", one is a 6 pin which has another 2 pins (total of 2x4: 8) branching off from the main one and then another six pin cord. How do I know if I should do 8:6 or 6:6? Or is it just implied that you always fill all power pin slots? I just want to make sure I am doing it right because I don't want to ruin anything! Hope this wasn't too confusing, I tried to be descriptive as possible. Thanks!
