KHACHIMO 1U 250W ATX Power Supply DPS-250AB-89M

SKU CH-3KER-N2RAN

A 250 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for quiet, low-power systems

  • TypeATX
  • Modern Standby compatibility enables rapid wake-from-sleep
  • 80 PLUS Gold certification delivers high efficiency for lower power use
  • Zero RPM fan mode stops the fan at low loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 1U 250W ATX form factor fits compact server and workstation builds

Compact 1U ATX power supply

The KHACHIMO 1U 250W unit fits slim chassis that require an ATX-form-factor supply. It targets system integrators and builders working with low-profile enclosures where standard-height units will not install.

80 PLUS Gold efficiency and quiet modes

Gold-rated efficiency reduces waste heat and lowers overall power draw. The Zero RPM fan mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states.

250W limit for low-power builds

The 250W ceiling restricts use to platforms with modest CPU and GPU demands. Systems needing high-end graphics cards, multiple drives or heavy overclocking will exceed this capacity and require a higher-wattage design.

Questions about this item

Will the fan in this 1U 250W unit need replacing after continuous use?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing mechanical wear and extending the fan's operational life before any replacement is needed.

What limits sustained output before the 250W rating is reached?

The 80 PLUS Gold certification ensures high efficiency up to the full 250W capacity, so thermal limits or protection circuits engage first if that wattage is exceeded continuously.

How much noise and heat does this supply produce when running all day?

Zero RPM Fan Mode keeps it near-silent at typical loads, while 80 PLUS Gold efficiency and LLC topology with DC-to-DC conversion minimise waste heat and coil whine during extended operation.
