KHACHIMO DPS-250AB-55 B 250W ATX power supply

SKU CH-TZBK-X4GXG

A 250W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep times and better low-load efficiency
  • 80 PLUS Gold certified efficiency for lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 250 W ATX form factor fits standard desktop builds and replacement needs

Compact ATX power supply for modern standby PCs

The KHACHIMO DPS-250AB-55 B is a 250W ATX power supply built for systems that use Modern Standby sleep states. Its 80 PLUS Gold certification means high efficiency at typical loads, reducing heat and electricity draw. The resonant LLC topology with DC-to-DC conversion delivers clean, stable voltage rails for sensitive components. Zero RPM fan mode keeps the unit silent during light workloads.

Suited to low-power builds needing quiet sleep

This unit fits compact or office desktops that prioritise fast wake times and silent idle operation. Builders who need higher wattage for discrete graphics cards or multiple drives should look at larger-capacity supplies. Systems requiring server-grade redundancy or specialised form factors such as SFX are not addressed by this model. The 250W limit also rules out high-end gaming configurations.

Fan behaviour and topology shape daily use

Zero RPM mode stops the fan completely at low and medium loads, removing audible noise during routine tasks. The resonant LLC and DC-to-DC design reduces coil whine, so the supply stays quiet even when the fan spins. Modern Standby compatibility lets the PC enter and exit deep sleep states quickly without power instability. No extra cables or software utilities are mentioned in the specifications.

Domande su questo articolo

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

It uses the standard 24-pin ATX main connector and a 4-pin or 8-pin CPU power connector, both of which must be seated for the supply to start.

Will the 80 PLUS Gold efficiency and LLC topology work with an older motherboard that lacks Modern Standby support?

Yes, the efficiency rating and resonant LLC topology operate independently of Modern Standby; the supply delivers clean power and high efficiency on any ATX-compatible board.

How can I confirm the Zero RPM fan mode is active after assembly?

With the system at idle or light load, the fan should remain completely still; you can verify by watching the fan blades or listening for silence at the rear grille.
