How can I get a smps to operate without connecting it to the computer?
Occasionally I am given a power supply module from a computer to troubleshoot or confirm proper operation.Many of these do not work disconnected without a load. They simply just sit there. With a few simple items I built a test “jig”. These supplies usually have one or two +5v sources, a -12v, and a +12v source. Simply place several 12v automotive bulbs and several common 6v bulbs on a small wooden block for stability. Use sockets or any way to mount them. On each bulb, attach two “clip leads”(+ and ground). You can color code them if wanted. Simply clip the 12v and 6v leads to proper outputs of power supply and you have a good “dummy load” to operate it separated from its computer. Gives a good visual indication, too.
