Compact ATX power supply unit with matte black finish and visible cooling fan grille

KHACHIMO

KHACHIMO 250W ATX power supply Gold 0 RPM LLC DC-DC

SKU CH-77JM-2JYJR

An 80 PLUS Gold ATX power supply delivering 250 W with zero-RPM fan mode and LLC DC-DC topology for silent, efficient operation

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold certified for high efficiency and lower heat
  • Zero RPM fan mode stops the fan at low loads
  • LLC resonant topology with DC-DC conversion delivers clean power
  • 250 W ATX output for compact system builds

Suitable Systems

This 250 W ATX unit is built for low-power desktops and small-form-factor PCs that use modern standby sleep states. Offices, home-theatre rigs and basic productivity machines will benefit from its Gold-rated efficiency and near-silent fan behaviour.

Less Suitable Scenarios

Builders who need more than 250 W of continuous output or who run multi-GPU configurations should look at higher-capacity supplies. Systems with power-hungry discrete graphics cards or heavy overclocking loads fall outside this unit's design envelope.

Deciding Specification

The 80 PLUS Gold certification confirms high efficiency at typical loads, reducing waste heat and enabling the zero-RPM fan mode to stay active longer. This single rating tells you whether the PSU matches a quiet, energy-conscious build.

Questions about this item

What motherboard power connector does the 250W ATX unit require to function?

It uses the standard ATX 24-pin motherboard connector; your motherboard must provide the matching socket.

Will the Zero RPM fan mode stay off when paired with an older CPU that idles at higher wattage?

The fan remains off at low and medium loads; if the legacy CPU draws enough power to exceed the medium-load threshold, the fan will spin up automatically.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Monitor input versus output power with a watt-meter; at typical loads the unit should meet the 80 PLUS Gold efficiency targets listed in its certification.
