myVolts 300W AT Power Supply Module 12V DC Input 24Pin

Compact AT Power Module for Small-Form Systems

This 300W AT power supply module accepts a 12V DC input between 11.4 and 12.6V and delivers power through a 24-pin ATX connector. It is built for mini-ITX and 1U chassis where space is tight and a compact DC-to-DC solution is required. Industrial solid capacitors provide high temperature resistance and stable operation. The module suits embedded PCs, HTPCs, POS terminals and similar low-profile deployments.

Plug-and-Play Install with External Adapter Needed

The board measures approximately 154 x 35 x 15mm and includes a 24-pin to 20-pin cable, a DC input cable and an AUX cable for direct connection. Installation is straightforward: connect the supplied cables and plug into the motherboard. The unit requires a separate 12V DC power adapter capable of at least 25A input current; without it the module will not function. Over-current and short-circuit protection guard the system during wiring mistakes.

Steady 85% Efficiency Under Continuous Load

Rated at 300W output with 85% power efficiency, the module is designed for sustained operation in environments from 0 to 55°C and 45% to 75% humidity. Solid capacitors maintain reliability during extended use in mining machines, servers or digital signage players. It is not suited for builds that need ATX-standard AC input or higher wattage headroom for multi-GPU configurations.
