Hey guys! I've got a problem with my new pc build. I installed my new Gigabyte Radeon HD 7970, and I have no power to it. I have an 850 watt PSU, so that shouldn't be the problem. Any advice?

I have a Corsair AX 850. Uhm, I have a dual head PCIE 6 and 8 pin cord. What's the 6+8 pin?

Edit: Never mind, I think that's exactly what you meant.

yeah I meant 6 and 8 pin. Too lazy to type 'and'
I see it seems weird your AX850 is as good as a psu can get.
So when you turn on the computer, do the fans on the gpu turn on?

Nope, no fans. No video output.

don't mean to be that guy, but double check the gpu is all the way into the slot and both PCIe power connectors are plugged in right. If that doesn't help then I would assume you got a case of faulty gpu/psu. Though I am leaning towards faulty gpu.
