Is putting a 24 pin power supply in a 20 pin motherboard possible? The pinout seems to be the same with the exception of the extra 4 pins. What I am thinking is that I could just hang those extra pins over the end of the motherboard connecter. Would this work? Will it damage anything?
Yeh, you can hang the extra 4-pins off the side so long as there isn't another component in the way. But you usually don't have to, as most 24-pin power supplies now use a split connector with a 4-pin segment clipped to a 20-pin segment.
