ATX power supply; how do I switch on?
I am using an older ATX computer power supply for a stepper motor drive, and I need to know what do I have to do to switch it on, what color wires in the main plug would I connect to make it run? Really I need to simulate the connection that the motherboard makes when you boot the computer up, to output the main power to the rest of the computer. Thanks!
ATX power supplies are started up by shorting the pin with the green wire to ground (any pin with a black wire). This is on the 20 or 24 pin connector that goes from the power supply to the motherboard.
