myVolts 120W AT Power Supply Module with 24Pin ATX/DC Cable

SKU CH-4KZ9-MBHY9

Compact 120W AT module converts 12V DC to ATX power for mini PCs, HTPCs and servers, with over-current and short-circuit protection

  • TypeAT
  • 120W output powers compact systems efficiently
  • 12V DC input requires matching adapter for operation
  • Industrial solid capacitors resist heat up to 55°C
  • Over-current and short-circuit protection safeguards components
  • 24-pin ATX cable enables direct plug-and-play installation

Compact AT power module for space-constrained builds

The myVolts 120W AT module delivers DC-to-ATX conversion for mini PCs, HTPCs, POS terminals and similar low-power systems. It accepts a 12 V DC input and supplies up to 120 W through a 24-pin ATX cable. An external 12 V adapter is required and is not included.

Thermal and electrical behaviour

Rated efficiency reaches 90 % under normal load, limiting waste heat inside tight chassis. The unit operates from 0 to 55 °C and 45 to 75 % humidity, while industrial solid capacitors provide high-temperature resistance. Over-current and short-circuit protection guard connected components.

Included cables and their effect

A 24-pin to 20-pin adapter cable and a DC input cable ship in the box, enabling direct connection to both modern and legacy motherboards without extra purchases. The board measures approximately 120 x 28 x 20 mm, so it fits ITX cases and similar enclosures. Buyers needing higher wattage or an integrated AC inlet should look elsewhere.

Questions about this item

How do I install the module and connect the 24-pin ATX cable without bending pins?

Mount the 120 x 28 x 20 mm board in the chassis, plug the 24-pin ATX cable straight into the motherboard header, then attach the DC input cable to a 12 V adapter within the ±5 % tolerance.

What maintenance or replacement will the industrial solid capacitors need over time?

The solid capacitors are rated for high-temperature resistance up to 55 °C operating temperature; no scheduled replacement is required unless the unit exceeds its 0–55 °C working range.

At what point does the 90 % efficiency limit cause thermal throttling under sustained load?

Continuous 120 W output at 90 % efficiency generates 12 W of heat; if chassis airflow cannot keep the module below 55 °C, the over-current and short-circuit protections will activate first.
