Go Nvidia
So I thought it was rediculous that I had to connect a seperate rail power supply to my video card last year. Yet Nvidia one up-ed that. CHeck those quote out:
I am sure you have seen the pictures of the NV40 boards floating around here and there, and saw the two molex connectors sticking off the back. If this didn’t clue you in, let me tell you right out, Nvidia will be unchallenged in the power race. It seems each of those connectors will need to be plugged into a separate power rail, and nothing else can be plugged into that rail. OK, they will let you put a fan into it, but anything more is strictly forbidden.
