I've started to assemble my new PC and when I've finally attached my Gygabyte NVIDIA GPU (GTX 760), it needs some kind of PSU power, in the form of 6 + 8 holed socket. So far so good.

My PSU (Cooler Master G650 M), provides 2 PCI-e cables, and EACH of these 2 cables, provide this ending: 6+2 and 8 (cable 1), 6+2 and 8 (cable 2)

Ok, my doubt is: Can I use the "6+2" and "8" endings OF THE SAME cable? (leaving a full PCI-e cable unattached) Or do I have to use the 6+2 from one of the cables and the 8 from the other, using thus both cables at the same time?

Thanks

  • What does the manual say? It's normal to use a single PCI-e power cable for a single device though, wouldn't make sense, to use 2 cables for a single device

  • Nothing in either direction, just a drawing.

    You should be able to use the 6+2 in one card. The idea is those who have dual/SLI setups then two cards will require power.

  • I don't understand if that answers my accurate question... I have just one card, but 6 + 8 holes...

  • Both those PCIe cables eventually hit the same internal power rail inside the PSU.

You can do it either way. The reason for the multiple connectors is to stay within the power limitations of the connectors.
