Oh Happy Day! I got my new (to me) Power Supply, that I got at the Club Meeting, to fire up. Thanks Matt. Per Matt: "you just hook the green and the purple leads together." The problems is, there are two greens and two purples. To make a long story, short, the magic pins are 4 and 13 on the DB-15 connector. So now you are asking, how do I tell which pin is 4 and which is 13? Well, if you were an electronics expert like me, you would know that the far left pin in the upper row is pin 1, and that the far right pin in the lower row is pin 15. (or you could carefully look at the face of the connector and see the there is a small number next to each pin).
To open the case, remove five phillips head screws from the small cover, remove cover. Remove the front cover assy by removing four torx head screws, you will need a size 15 torx screwdriver. As you remove the front cover, you will need to unplug two connectors to seperate it from the rest of the case. Next, unplug three connectors that run between the case halves, remove four phillip head screws that hold the case halves together. To get to the DB-15 connector and output connector (the one with the red, brown, yellow, and black wires) you will need to remove two "L" brackets from the bottom of the case, and then remove the large circuit board by removing four large phillips head screws, one of the screw is somewhat buried under the mass of red, brown, yellow, and black wires. Now remove the two guide pins the hold the DB-15 connector in place, these just unscrew from the outside. To remove the large connector, you can cut the plastic wing pin off, or carefully wrap the wings back around the center pin until they will go though the hole in the case. Remove the third guide pin.
Things you need to know:
1) The red wires that go to the big connector are 5V, brown are 3.3V, yellow are 12V, and black are GND.
2) Don't touch the small IC's and stuff on the small (daughter) boards as you work on your power supplies, static electricity from your fingers can Zap these. The daughter boards are the smaller boards that stick out of the larger (mother) boards. (Don't ask me who the father was). Handle by way of the case and large heat sinks as you work. Remove all metal chips as you drill holes.
3) Remember how you took it apart so that you can put it back together.
Put a switch between the wires from pin 4 and pin 13 for an on/off power switch.
