Benchtop ATX Breakout Board

The myVolts breakout board converts a standard ATX power supply into a benchtop unit with four voltage channels. A 24-pin connector accepts both 20-pin and 24-pin plugs, while a built-in switch and power indicator give direct control. The module measures 128 by 48 by 30 millimetres and includes a gasket to prevent short circuits.

Makers needing adjustable rails, not PC builders

Hobbyists developing embedded projects gain quick access to 3.3 V, 5 V, 12 V and -12 V rails without splicing wires. The onboard USB port supplies 5 V for convenient device charging or powering small modules. Builders assembling a complete computer gain no extra motherboard connectors or cable management features from this board.

24-pin ATX input with USB 5 V output

The single specification that decides fit is the 24-pin ATX socket compatible with 20-pin plugs. If your power supply uses this standard connector, the board delivers four regulated voltages plus a USB 5 V port for bench use. Any supply lacking the 20- or 24-pin ATX interface cannot connect.

Questions about this item

How much heat or noise does the 24-pin ATX breakout board add when running all day?

The board is a passive connector with no fan or active components, so it adds no audible noise and negligible heat beyond the power supply itself.

What must I already own for the 20/24-pin breakout board to function?

You need a standard ATX power supply with a 20-pin or 24-pin main connector to plug into the board.

Will the 24-pin breakout board work with an older 20-pin ATX power supply?

Yes, the 24-pin socket is compatible with 20-pin plugs, so it fits older ATX units without an adapter.
