Use an ATX PC power supply as a 5V, 3.3V, and +12V/-12V bench supply the easy way, without cutting the case or mounting external connectors, resistors, LEDs, switches, and fuses. Provides visual indication when supply is plugged in and turned on, also fuses the power voltage outputs for safety. Run USB powered development boards via the USB connectors on the 5V line.
