I saw a post in here about someone changing there power supply fan and it reminded me with what I did with my computer. I have used all the molex on my regular PS running the mother board, hd, and cd-rom. I love the idea of alot of fans and I like the sound of them while I sleep so I have alot running in my case. BUt soon I ran into a problem. No way to power all of them. So I came across an old PS and it wouldn't work with any new mother boards and had a switch to turn it on. So you didn't need a mother board to turn it on. So I set the PS on the bottom of the case ran the switch out side of the back of the case and connected some fans to the PS and wallah! I have more spots for fans or anything else that needs power. Ill post the pics today or tomorrow if I remember.

You can actually make more modern PSUs (ATX PSUs as opposed to your AT one) turn on by connecting the green wire on the motherboard power connector to a black wire on the same connector, a paper clip or a piece of wire will do the trick. You could add a switch in there too if you wanted, it's safer than a live switch with 110/220v on it covered only by a thin piece of (likely old and weakened) rubber.

well the problem with that is that there are 7 black wires on that same connector.
