How to use a common atx computer power supply to get 12 volts dc?
(1/3) > >>
michelevit:

I am looking to power some 12 volt devices (small amplifier, lights, and case fans)
I have several ATX power supplies from computers and was would like to draw
the power from it. I know the ATX power supply has some sort of triiger to power it on.
Does anyone know which wires need to jumped to turn on the power supply?
This power supply would be seperate power supply from the one that is powering
the pc already is in the cabinet.
Any advice is greatly appreciated. Thanks for providing this forum. I have learned
a great deal from just lurking.

it is pretty easy if you know you way around circuts and a soldering iron.

check this:http://www.instructables.com/id/E6D9DB9RPPEP286BR9/ site for step by step instructions.

your 12v circuit would be the yellow wire and the black wire next to it on the connector that hooks to a drive unit.  The other two wires are for the 5v circuit.
RayB:
Check with a volt meter. Some manufacturers reverse the color coding.
