  • Requires 12 V DC adapter to deliver 300 W output

300W AT Power Module for Compact Builds

This 12V DC input module delivers 300W through a 24-pin ATX connector, targeting mini-ITX and 1U chassis where space is tight. It requires an external 12V adapter capable of up to 25A to operate.

Fits Mini-ITX and 1U Cases

The 154 x 35 x 15mm board slides into small enclosures and frees internal volume by moving the AC-DC conversion outside. Included cables provide 24-pin, 20-pin, AUX and SATA connections for motherboard and drive power.

300W Headroom with 85% Efficiency

At 85% efficiency the module handles typical embedded, HTPC or server loads within its 0-55°C operating range. Systems demanding more than 300W or lacking a suitable 12V external supply will need a different solution.

Perguntas sobre este artigo

What sustained-load limit does the 12 V DC input hit first?

The module draws up to 25 A at 11.4–12.6 V, so the adapter must supply at least 300 W continuously.

How much heat and noise appear when it runs all day?

No fan is included; the board relies on case airflow and operates at 85 % efficiency within 0–55 °C.

What separate 12 V source must I already own?

A 12 V DC adapter rated for 25 A or more is required; the module does not generate its own input power.
