OK I've read a lot of these power supply conversion threads. Most issues revolve around This color wire..to this color wire..but my wires are colored like this or my connector is 20 pin vs 24 pin. Its gets SOOO confusing. The fact is not all manufactureres use the same color wires.
It is a fact however that ALL ATX supply connectors are wired the same to the connector. Here is my attempt to clear the air on how to wire the connector to trick the supply to turn on in the absense of a PC motherboard. I've done this on several older 200watt ATX supplies and new 500 watt supplies. So here is my diagram. Hope its done clearly enough. If I didn't fudge anything by accident I think this should be the end all and relief for most people. I think in general a 10watt 10ohm resitor is enough. If it requirs any modification let me know, we can iron out any problems with the diagram and then Mods should just sticky this particular picture for that portion of the supply conversion that hangs everyone up.
