Compact 250 W DC-ATX power module

The myVolts Pico PSU delivers up to 250 watts from a 12 volt DC source through a 24-pin ATX connector. It is aimed at builders of Mini-ITX systems, embedded PCs or vehicle installations where a standard AC power supply is impractical. The 25 centimetre cable keeps routing tidy inside small chassis. Short-circuit protection shuts down the output if a fault occurs.

Replaces bulky AC units in space-constrained builds

This module removes the need for a full-size ATX power supply when the system runs from a 12 volt DC supply such as a vehicle electrical system or an external DC brick. The jump is worthwhile when chassis volume is at a premium and the total component draw stays within the 150 to 250 watt range. It is not for systems that require AC mains input or that exceed the rated DC output capacity.

Plugs straight into the board

Installation consists of connecting the 24-pin ATX plug to the motherboard and the barrel jack to a compatible 12 volt source; no additional cables or adapters are included. The 25 centimetre lead length suits Mini-ITX layouts but may fall short in larger cases. The most common issue is mismatching the barrel connector polarity or inner/outer diameter, so verify the source plug before powering on.
