if you do have a PSU that has the 8 pin, and the 24 pin, should you connect them all? Or is that bad? The reason I ask is, my friend has a mobo that is a core 2 duo board, and it doesnt have 24 or 8, it has 20 and 4 right on the board, no extra plugs at all. And his board works fine that way. But if you have the PSU with the 8 and 24, and your board has 8 and 24 on it, should you plug them all in, or will it work with just 20 and 4? Sorry about all the confusion, I never worked with this new pin set up, hehe.
