myVolts 300W Power Supply 12V DC ATX Module

SKU CH-DY6P-963SD

Compact ATX module converts 12 V DC to 300 W with 85 % efficiency, full protection and 24-pin cable for mini-ITX or 1 U builds

  • TypeAT
  • 300 W output powers compact systems
  • 12 V DC input with 11.4–12.6 V range simplifies wiring
  • 85 % efficiency reduces heat in tight cases
  • Industrial solid capacitors withstand 55 °C operation
  • 24-pin ATX cable plus 20-pin adapter enables plug-and-play install

Compact 300W ATX module for mini-ITX builds

This 12V DC input power supply module delivers 300W output for mini-ITX and 1U chassis applications. It targets builders of HTPC, POS terminals, digital set-top boxes and similar compact systems. Industrial solid capacitors provide high temperature resistance and stable operation between 0 and 55 degrees Celsius.

Direct 24-pin ATX connection with included cables

Installation uses the supplied 24-pin to 20-pin cable, DC input cable and AUX cable for plug-and-play setup. The module requires a separate 12V DC adapter capable of at least 25A input current. Builders must verify adapter capacity and cable routing in tight 154 x 35 x 15mm board dimensions to avoid airflow obstruction.

85% efficiency ceiling and 12V DC input constraint

The unit accepts 11.4 to 12.6V DC input and converts it at up to 85% efficiency, limiting practical output under sustained load. Overcurrent and short-circuit protection safeguard connected components. Systems needing higher input voltage ranges, redundant supplies or ATX12VO native support fall outside this module's design scope.

Perguntas sobre este artigo

How do I verify the 300W 12V DC ATX module is working after connecting the 24-pin cable?

After wiring the 24-pin ATX cable to the motherboard and the DC input cable to a 12V source, the board should power on without triggering the overcurrent or short-circuit protection. Stable voltages on the 24-pin rails and no shutdown under load confirm correct operation.

What cables and accessories are included, and what must be sourced separately?

The box contains the 300W module, a 24-pin to 20-pin ATX cable, a DC input cable and an AUX cable. A 12V DC power adapter capable of at least 25A is not included and must be purchased separately.

Which version should I choose for a mini-ITX or 1U chassis?

The single 300W 12V DC input model with the 154×35×15 mm board is designed for mini-ITX and 1U cases; no other capacities or form factors are offered in this listing.
