myVolts XH-M229 ATX Power Supply Module 5pcs

SKU CH-184N-86E5V

ATX adapter board with 24-pin connector, four voltage outputs and built-in protection circuits, supplied as a pack of five modules

  • TypeAT
  • ATX adapter board with 24-pin connector
  • Four independent voltage output sets per module
  • Built-in overcharge, over-discharge and overcurrent protection
  • Intelligent auto-stop prevents device overcharging
  • Compact 12.8 x 4.8 cm board fits standard chassis

ATX adapter board for desktop builds

This myVolts XH-M229 module converts a standard 24-pin ATX connector into four separate voltage outputs for test benches or custom chassis wiring. It suits technicians and hobbyists who need quick access to individual rails without cutting into a main harness. The board includes an onboard switch for manual power control during bench sessions. It is not for builders who need a complete enclosed PSU with certified safety ratings.

Fits open-frame test setups and modded cases

Each module measures 12.8 by 4.8 centimetres and plugs directly into the motherboard power header, freeing the builder from routing bulky 24-pin cables through tight cut-outs. The four distinct output groups let you feed drives, fans or custom lighting from a single ATX source. No additional connectors or soldering are required for basic operation. It does not replace a full ATX power supply for closed-case systems.

Passive cooling with protection circuits

The board relies on natural airflow across its exposed PCB, so noise is limited to the host power supply fan. Integrated safeguards provide overcharge, over-discharge and overcurrent protection while automatically stopping output when a connected load reaches full charge. A relay status indicator shows active operation at a glance. No active cooling or temperature-controlled fan header is present on the module.

Questions about this item

What protection limits does the XH-M229 module trigger first during continuous operation?

The module provides overcharge protection, over-discharge protection and overcurrent protection to stop unsafe conditions before they damage connected devices.

How much heat or noise does the 12.8 × 4.8 cm board produce when running all day?

The adapter board has no fan or moving parts, so it generates minimal heat and operates silently under normal loads.

Which ATX power supply connector must I already have to use these five modules?

Each module requires a standard 24-pin ATX connector from an existing desktop power supply to deliver its four output voltage sets.
