Professional 300W AT Module

The myVolts Asixxsix is a 300 watt AT-type power supply module that accepts a 12 volt DC input between 11.4 and 12.6 volts. It is built for mini-ITX and 1U chassis used in HTPC, POS, digital set-top box, network server, AD machine, bank terminal and mining machine applications. The board measures approximately 154 by 35 by 15 millimetres.

Included Cables and Protection

The package supplies a 24-pin ATX cable, a 24-pin to 20-pin adapter cable, a DC input cable and an AUX cable so the module plugs directly into standard motherboard headers. Industrial solid capacitors provide high temperature resistance and stable operation. Over-current and short-circuit protection circuits guard connected hardware.

Installation Notes

Mount the compact board inside the target case and connect the supplied cables to the motherboard and a suitable 12 volt DC power adapter rated for at least 25 amps. The unit operates from zero to 55 degrees Celsius at up to 75 percent humidity. Ensure the external adapter meets the required input current or the module will not deliver full output.

Perguntas sobre este artigo

Will the industrial solid capacitors need replacement after extended 24/7 operation?

The module uses industrial solid capacitors rated for high temperature resistance, designed for stable long-term use in continuous applications such as servers and mining machines.

What is the first limit reached when running the 300W output continuously?

The 12V DC input draws up to 25A, so the external adapter’s current rating becomes the limiting factor before the module’s own 300W output ceiling.

How much heat and noise does the module produce inside a 1U case all day?

With 85% efficiency at 300W, about 45W becomes heat; the board has no integrated fan, so system airflow must handle dissipation, and noise depends entirely on the case cooling solution.
