Jumpstarting a power supply.

[pirred908]

I took the power supply out of an old IBM computer. It doesnt have the standard "ATX" power plugs. I believe the style of the power connectors on it are called "P6", but the actual connectors themselves say "P1" and "P2". I'm trying to use this power supply to run 2 fans and a water pump. I tried just plugging it into the wall, but it didn't respond. I'm think I need to "jump start" it to get it going. On a standard ATX connector, you would connect the green and black wire, correct? What wires do you connect on this power supply to start it? The "P1" connector has: black, black, blue, yellow, red, and orange. The "P2" connector has red, red, red, white, black, black.

If this is an IBM-brand PC, You have to flip a switch on the side of the unit to turn it on, I believe.

HTH.

There is no switch.

Hi, You have to add the switch on an AT power supply. There should be four leads in a heavy cable with, usually, push on female connectors. The wires are usually 2 White and 2 Black. The double pole single throw switch should connect black to black and white to white. Get it wrong and the house circuit breaker will blow. If you have access to an Ohm Meter there will be a short circuit (Zero Ohms or close) across the two AC input pins on the back of the power supply if you got it wrong. If the supply has its own switch on the back you can just connect the black to black and white to white and use the existing switch. Jim

Gosh, would it be easier to just buy a new power supply from a computer store? Don't really want to go through all that.
