The board let you recycle an ATX computer power supply into a powerful bench tool that powers your projects. The ATX breakout board routes the -12, 3.3, 5 and 12 volts ATX outputs to screw terminals, each protected by a 1.25 amp resettable polyfuse. These four voltages cover many common electronics needs, there's even a negative voltage (-12 volts) for op amps and audio projects. An on/off button and a control circuit are included on-board, no modifications to the ATX supply are needed.
