EDIT: I saw your comments on the adapter, I had no problems with it, as long as you got a good power supply.
It's a 980w, but there are no Molex connections or extra connections. The PCIe power cables plug into the motherboard/logic board.

Like I said, it's the system in my signature. The PSU, and power system is proprietary unfortunately.
They're rated for 225W through the motherboard, anymore and it could blow the board.
Some folks use a 6-8 pin adaptor, some have success, some have issues, few end up with a dead system.

I'll see what the TDP ratings are, and if it's not too far above 225W, I might take a chance depending on performance, and driver availability.
