Requirements
Minimum of a 450 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 24 Amps.)

Increasing the wire gauge decreases resistance (because electrons have more area to flow through).

I mentioned the possibility of multiple rails above. However, the corsair PSU mentioned above (and the one he ultimately bought), has only one 12v rail, so this does not apply. The only concern is getting enough current to the video card without putting too much through an individual cable to the point that it fails.

it would be totally fine to use a PSU that doesn't have the two 6 pin connectors
