Hi

I am trying to power two ATI 7950. One has 12 plug connection and the other 14 plugs.

I have used all the PCI plugs and the molex adapters that come in the box but there aren't enough. My PSU doesn't have enough cables.

What can I do? Is there a way of splitting a molex into more?


PSU: Cooler Master GX650 Bronze 80 plus.

I will assume your native language is not English?

I'm also assuming you mean Radeon HD 7950, since ATI was taken over by AMD way back in the dark ages.

Finally, I'm going to assume that one of your cards require 2 x 6-pin plugs, and the other requires 1x 6 and 1x8 pin plugs.

Each Molex connector can handle 132 watts if I recall correctly. a 6-pin connector can handle 75 and a 8-pin 150w. The PCIe slot can by itself provide 75 watt.

So I guess you need to buy a stronger PSU that may have more connectors? It would seem that you are already absorbing all the anticipated power draw from your PSU if you have no spare Molex or other cables and you cannot jiggle them around to share the power draw within tolerance?
