PSU with four six pin PCIE Connectors
I'm planning on going crossfire in the future (yes I know about all the problems, don't care) and I need a power supply with about 700w of power and the aforementioned 4 * 6 pin PCIE connectors.
Most power supplies of that rating will come with 4 PCIe connectors at the very minimum.
I suggest the Seasonic X-650 GOLD. It's one of the best made power supplies out there. (Seriously, go read some reviews - it's an incredible little thing. )
