I have several EVGA PSUs. They consist of 650 G1, 1200 G+, 1300 G2, 1600 T2, 1600 G2. Some of the cables have gotten mixed up. How do I identify which cables are for which PSU? Specifically the VGA cables. I believe the VGA cables for the 650 G1 are marked with G1 on the VGA cables. The other VGA cables do not have any markings on them and I don't see away to identify which PSU they go with. I believe the CPU, SATA and Perif are interchangeable between the different PSUs.
