myVolts Adjustable ATX Breakout Adapter 13-24V to 1.8-10.8V Acrylic Case Kit

SKU CH-69T2-YQ7F5

Adjustable ATX breakout board converts 13-24 V input to 1.8-10.8 V output up to 3 A with touch switch, LED display and acrylic case kit

  • TypeAT
  • Touch switch toggles output and display
  • Adjustable 1.8-10.8V output from 13-24V input
  • Fixed 3.3V, 5V and 12V rails for ATX
  • Reverse-polarity and short-circuit protection built in
  • Acrylic case kit included for bench use

Adjustable ATX Breakout Adapter

This adapter converts a DC input between 13V and 24V into adjustable outputs ranging from 1.8V to 10.8V, with stable rails at 3.3V, 5V and 12V. It is built for engineers and hobbyists who need a compact bench supply for ATX-style prototyping. The kit includes an acrylic case and banana plugs for immediate use. It is not suited for builders who require a full ATX power supply with standard motherboard connectors.

3 A Maximum Output Current

The single specification that decides fit is the 3 A maximum output current across the adjustable range. This limit determines whether the board can drive your specific load without triggering protection. The adapter also provides input reverse-connection protection and short-circuit protection for safe experimentation. Buyers needing higher continuous current for larger systems should look elsewhere.

Sustained Load Behaviour

Under continuous load the board maintains regulated voltage up to the 3 A ceiling, while the touch sensor switch allows instant output shutdown without disconnecting the source. The LED display shows real-time input and output voltages during operation. An acrylic enclosure kit is supplied to protect the PCB during extended bench sessions. It is not designed for enclosed, fanless installations where heat cannot dissipate.

Questions about this item

What does the 3 A maximum output current mean when I plug this into a real ATX board?

It limits the combined draw on the 3.3 V, 5 V and 12 V rails to 3 A, so the adapter can run low-power boards but not a full desktop CPU and GPU.

The input is quoted as DC 13 V–24 V — what does that range cap in practice?

You must feed it a DC source between 13 V and 24 V; anything outside that window will not power the board or may trigger the protection.

Will the 99 mm × 60 mm acrylic case kit fit a standard ATX cut-out?

The board measures roughly 99 mm by 60 mm, so the included acrylic shell matches those dimensions and mounts directly on the PCB.
