I have a question about powering GPU's, that's likely ridiculously simple.

I have 6 EVGA 1070 TI's and each has two 6 pin inputs going to it. If I'm powering these off an EVGA 1000 watt P2 power supply, do run two to 6 pins to every GPU? If I do that, then I don't have enough 6 pins for every card. I.E, I'd have two 6 pin connectors off each PS output to one card. Only allowing me to connect 3 cards. How do I get the 12 connections I need for the GPUs off the 6 connector PS?

Thanks!
