PCIe Cable Pinouts?

[sushisky]

Hi, so I just got another gtx 980 to put in a sli config, but I lost other set of pcie power cables that came with my ax760 psu. As it happens, I have a spare xfx proseries 750w power supply lying around with all its cables. I was wondering if it would be alright to use the pcie power cables from the xfx psu, since different PSUs have different pinouts. I checked the overclock.net power supply pinouts, but all the power supply pinouts are limited to the 24pin to 28pin connectors (which have the same pinout for both the AX760 and XFX 750W). Are PCIe power cables pinouts universal across all PSU manufacturers?

The pci-e cables are basic, one row of 12v (yellow) wires, one row of ground (black) wires. If you have a digital multimeter, you can check which pins on the power supply header are the 12v and which are ground and figure it out.

 

XFX uses Seasonic as OEM, AX760 is also made by Seasonic so chances are it's the same connector.
