GTX 1080 power connector confusion

[Foustian]

I have a GTX 1080 with two 8-pin power connectors. It came with 2 8-pin to dual 6-pin cables. I also have a Seasonic G-550 PSU which came with 2 8-pin to 6+2-pin cables. I don't understand what I'm supposed to connect to what. Do I plug each of the PSU cables into one of the 6-pins on each GPU cable? Or do I only connect one GPU cable and plug both PSU cables into it? Thanks for any help you can provide.

All you need to do is directly connect the two PCIe 6+2 cables from your PSU into the GTX 1080 8-pin sockets.

Edit for clarification: You don't need to fool around with any of the extra adapters because your PSU already fully supports the card with its 6+2 PCIe connections.

They look like this:

Thanks. This is only my second attempt at building a PC, and wiring is the hardest part.
