My graphics card has 6-pin pci-e slots and my power supply allso has two pci-e

[jackdevon]

I am not sure of the connection to the graphics card which has 2 6-pin pci-e slots and my power supply ANTEC has 2 6-pin plugs on the same cord do I plug in both or do I plug in one?

Both, unless there's another cable with 2 more, then I use 1 from each ( my choice, not mandatory )

jack, are you sure? That doesn't sound right. Which Antec PSU?

^ EA, NeoEco and HCG models use pigtailed pcie connectors.
The HCG750 has 4 connectors on 2 cables.
