Compact Pico PSU module with 24-pin ATX connector and 12V DC input

Vszerda

Vszerda 250W Pico PSU 12V DC 24-pin internal power cable

SKU CH-Z1Y9-CAHVR

A 250 W pico PSU converting 12 V DC input to ATX voltages via a 24-pin connector for mini-ITX or 1U systems

  • 250 W output powers demanding mini-ITX builds
  • 12 V DC input suits vehicle and compact systems
  • 90 % efficiency reduces heat and energy waste
  • Active PFC delivers clean, stable power rails
  • Industrial solid capacitors withstand high temperatures

250W Pico PSU 12V DC input

This 250W DC-to-DC module accepts a 12V source between 11.4V and 12.6V and delivers up to 21A on the input side. It provides +3.30V, +5.00V, +5.00VSB, +12.00V and -12V rails through a 24-pin ATX connector. The unit achieves 90% working efficiency with active PFC and uses solid capacitors for stability. It is designed for direct plug-in use with mini-ITX and 1U chassis.

Builders needing silent fanless power

The module operates without a fan, making it suitable for noise-sensitive desktop or server builds where a separate 12V adapter can be housed externally. It includes a 4-pin CPU power connector but provides no dedicated graphics card power pins, so systems requiring discrete GPU supplementary power cannot be supported. Users without an external 12V power adapter rated for the required input current should look elsewhere.

12V DC input voltage range

The supply requires a steady 12V DC source within the 11.4V to 12.6V window and a maximum input current of 21A to reach the full 250W output. If the available adapter cannot maintain this voltage under load or supply sufficient current, the module will not deliver its rated power.

Questions about this item

What power adapter must I already own for this Pico PSU to work?

You need a 12V DC adapter that can deliver up to 21A and stays within the 11.4 to 12.6V input range.

Will the 4-pin CPU connector on this unit power an older motherboard that uses an 8-pin EPS socket?

The module provides only a 4-pin CPU power connector; an 8-pin EPS motherboard would require an adapter or a different PSU.

How can I verify the 250W Pico PSU is delivering the correct rails after installation?

Measure the output terminals with a multimeter: you should see +3.30V, +5.00V, +5.00VSB, +12.00V and -12V within normal tolerances.
