myVolts 300W AT Power Supply Module 12V DC Mini-ITX 1U

SKU CH-A6A7-G7DY6

Compact AT power module delivers 300 W from 12 V DC input with over-current and short-circuit protection for Mini-ITX and 1U cases

  • TypeAT
  • 300 W output powers demanding mini-ITX builds
  • 12 V DC input simplifies integration with external adapters
  • Industrial solid capacitors ensure stable high-temperature operation
  • Over-current and short-circuit protection safeguards connected components
  • Compact 154 × 35 × 15 mm board fits 1U and space-constrained cases

Compact AT Power Module for Mini-ITX and 1U Systems

This 300 W AT-type power supply module accepts a 12 V DC input between 11.4 V and 12.6 V and delivers up to 25 A. It is built for Mini-ITX boards and 1U chassis where space is tight and an external adapter provides the DC source. Industrial solid capacitors give stable operation from 0 °C to 55 °C.

Plug-and-Play Install with Included Cables

A 24-pin ATX cable and a 24-pin to 20-pin adapter cable ship in the box, so the module connects directly to the motherboard without extra wiring. The DC input cable attaches to the required 12 V adapter. Over-current and short-circuit protection engage automatically if a fault occurs. The board measures approximately 154 mm by 35 mm by 15 mm, fitting the target form factors.

300 W Continuous with 85 % Efficiency

At full load the unit draws 25 A from the adapter and converts power at 85 % efficiency, leaving headroom for typical Mini-ITX platforms, HTPCs, POS terminals or thin servers. Output drops if the adapter cannot sustain 12 V at 25 A or if ambient temperature exceeds 55 °C. Storage extremes reach -40 °C to 70 °C, but operating limits are stricter.

Questions sur cet article

How can I confirm the module is delivering stable power after I connect it to a 12V DC source?

The unit includes over-current and short-circuit protection; if the system powers on and runs without shutdowns, the 300W output at 85% efficiency is operating correctly.

What cables are included and do I need a separate 12V DC adapter?

The package supplies a 24-pin to 20-pin ATX cable, a DC input cable and an AUX cable; a 12V DC adapter capable of up to 25A must be purchased separately.

Which version of the module fits a Mini-ITX or 1U chassis?

This single AT-type module measures 154 x 35 x 15 mm and is designed specifically for Mini-ITX and 1U cases.
