Step 2Connect the Neccessary Wires to the Connector.
Pinouts for the ATX connector can be found at:

or
http://pinouts.ru/Power/atxpower_pinout.shtml
The pinout is a little wierd, I think it was dreamed up by somebody who wasn't very familiar with electronics. Pin 1 and 11 are at the same end. Ditto for pins 10 and 20.
What I did to avoid confusion was to plug the connector into the power supply and note the color of the wires . Then I soldered wires to the following pins
Pin Standard Color My Color Use
1) Orange Orange +3.3V
7) Black Black GND
10) Yellow Yellow +12V ( I solderd two wires to this pin)
12) Blue Solid Grey -12V
13) Black Black GND
14) Green Green Switch on
18) White Grey/Red -5V
20) Red Red +5V
To finish off the connector I bundled the wires with some heat shrink tubing.
