20/24-Pin ATX Power Breakout Board with Display

Use a compatible ATX supply for an electronics bench project with this breakout board. It is for makers who can verify the pinout and output requirements.

• ✅ Connect a compatible supply — The board accepts twenty- or twenty-four-pin ATX.
• ✅ Read the output — The board has a voltage display.
• ✅ Use several rails — Terminals expose the listed ATX voltages.
• ✅ Choose a housing option — An acrylic shell version is separate.

Bring ATX outputs to accessible terminals

Confirm the power supply pinout and safe operating limits before connection. Use appropriate load protection and an enclosure.
