Ruth's sister 250W Pico PSU 12V DC 24-pin internal power cable

SKU CH-BRGX-BXHJ0

Delivers 250 W from a 12 V DC source via a 24-pin ATX connector for mini-ITX builds

  • Delivers 250W output from a 12V DC source
  • Accepts 11.4-12.6V input with 21A maximum current
  • Achieves 90% working efficiency for cooler operation
  • Uses industrial solid capacitors for high temperature resistance
  • Connects via 24-pin ATX and 2.5mm x 5.5mm DC jack

Compact Pico PSU for space-constrained builds

This 250W DC-to-DC module plugs directly into a 24-pin ATX socket and accepts 12V input through a 2.5mm x 5.5mm barrel jack. It delivers +3.30V, +5.00V, +5.00VSB, +12.00V and -12V rails at up to 90% working efficiency. The fully modular design uses industrial solid capacitors for stable operation in mini-ITX or 1U chassis.

Requires external 12V adapter

The unit draws a maximum of 21A from a 12V DC source operating between 11.4V and 12.6V, so a compatible brick or regulated supply is mandatory. It provides a 4-pin CPU connector and 24-pin motherboard connector only, with no dedicated GPU power outputs. This frees internal volume by eliminating a standard ATX PSU and its cabling.

Replaces full-size ATX units in silent, low-draw PCs

Builders moving from a conventional power supply to this pico module gain a fanless, noise-free solution for platforms that stay within the 250W limit. The jump is worthwhile when the build has no discrete graphics card and fits a compact case, but it cannot support configurations needing PCIe power connectors or higher total wattage.

Questions about this item

What is the maximum input current the 250W Pico PSU can draw at 12V DC?

The module accepts a maximum of 21 A at the 2.5 mm × 5.5 mm DC input connector.

How much heat and noise does the unit produce during continuous operation?

It runs without a fan, so it is silent; efficiency is 90 %, meaning roughly 25 W of heat at full load.

What external power adapter is required for the 24-pin ATX connector to function?

A 12 V DC adapter (11.4–12.6 V) rated for at least 21 A with a 2.5 mm × 5.5 mm barrel plug.
