This board allows you to utilize a standard ATX power supply as a bench-top supply. Just plug in the ATX connector into the middle of the board, plug the supply into the wall, and you're ready to go. Features an on-off switch, and breakouts of every rail: 12V, 5V, 3.3V -5V, -12V. Color coded mini-banana plugs let you connect temporary wires, or screw terms provide long-term connections. If you're already using an ATX supply to drive fans, or a high current device using the four-pin Molex connections, use this board as an easy on-off switch. Each rail is individually fused with 2AG mini fuses. Fuses and mini-banana plugs are sold separately.
