I have a Raidmax Hybrid 2 730ss power supply, which has 2 8 pin PCIe connectors connected to a single wire, and i was wondering if i could use that to power a new MSI GTX 1070 Gaming graphics card when it comes out. I saw that it has a 8pin and a 6 pin connector, so could i use the one PCIe cable, or do i have to buy a new power supply / use a molex connector for the other 6 pin?
