KHACHIMO

KHACHIMO power supply 420 560 740

SKU CH-CFVC-03DFG

ATX power supply compatible with 420, 560 and 740 watt server units, tested working

  • TypeATX
  • ATX form factor fits standard chassis
  • Tested working before shipment ensures reliability
  • Good quality components deliver stable power
  • Supports 420 560 740 watt models for flexible builds

Compatible ATX replacement for EFD series

This power supply fits the EFD-1K2S420DT, EFD-1K2S560DT and EFD-1K2S740DT models along with their DV variants. It is built for system builders who need a direct ATX-form-factor swap for those specific units. Buyers whose chassis require a different form factor or who need higher wattage than the listed models provide should look elsewhere.

Thermals noise and power draw in normal use

Each unit is tested working before dispatch to confirm stable output under load. The ATX design uses standard cooling airflow, so acoustic levels match typical power-supply behaviour in a ventilated case. Power draw scales with the connected components up to the rated capacity of the original EFD model.

How do I install the EFD-1K2S740DT in an ATX case and what step is often missed?

Mount the unit with the four rear screws, connect the 24-pin motherboard and CPU power cables, then verify the voltage selector matches your mains supply before switching on.

What maintenance will the EFD-1K2S560DV need over its lifetime?

Clean the intake grill and fan blades with compressed air every six to twelve months; replace the unit if fan noise increases or output voltages drift under load.
