The 2900XT has one 6-pin and one 8-pin power connector on it. the 6-pin isnt a problem, but can anyone show me a power supply that can power two of the 2900XT cards? I haven't seen one that can three 8-pin cables plus two 6-pin cables (one for the motherboard, two for the graphics cards, plus the PCI-E 6-pin cables)
