KHACHIMO

KHACHIMO 2700 2708 2710 2718 2810 2818 250W power supply

SKU CH-AGCY-W2E14

A 250 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for fast wake and quiet low-load operation

  • TypeATX
  • 80 PLUS Gold certification lowers energy use and heat
  • Zero RPM fan mode stops the fan at low loads for silent running
  • Modern Standby compatibility gives fast wake times and better low-load efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 250 W ATX unit fits models 2700, 2708, 2710, 2718, 2810 and 2818

Compatible models for 250 W replacement

This 250 W TFX power supply matches model numbers 2700, 2708, 2710, 2718, 2810 and 2818 along with part codes 447402-001, PS-5251-4, TFX0250D5W, TFX0250P5WB and TFX0250F5WA. It fits slim desktops that require the TFX form factor and an ATX-type connector layout. Buyers needing higher wattage or a standard ATX chassis size will not find a match here.

Sustained load behaviour with Gold efficiency

The 80 PLUS Gold rating means the unit maintains high efficiency across a wide load range, reducing waste heat during long work sessions. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and limits coil whine when the system draws steady power. Modern Standby support allows rapid wake-from-sleep without voltage droop.

Build quality and daily connectors

Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent operation for office tasks. The TFX enclosure uses the compact dimensions required by the listed models, so cable routing stays tidy in small cases. No modular cables are mentioned, so all leads are fixed to the unit.

Questions about this item

How loud and hot does the KHACHIMO 250W supply get during all-day use?

The 80 PLUS Gold rating keeps efficiency high, so less waste heat is produced, and the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

What must my case and motherboard already provide for this KHACHIMO unit to fit and start?

An ATX-form-factor bay and a standard ATX motherboard power connector are required for the supply to mount and deliver power.

Will the KHACHIMO 250W PSU work reliably with older components I plan to keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power that supports legacy parts and enables modern low-power sleep states.
