An old nearly ATX power supply set up for use as a bench supply. This needed a load on the +5V rail for the supply to operate. Instead of a resistor I used a 12V 10W (5W was too little load and 21W was unnecessarily large) auto lamp which doubles as pilot lamp. I have yet to fit a DC switch, the green switch wire is earthed till then.
