KHACHIMO PRT IPC-622 400W Power Supply PRM400

SKU CH-27Z0-S421W

An 80 PLUS Gold ATX power supply delivering 400 W with Modern Standby support, Zero RPM fan mode and resonant LLC DC-to-DC topology for quiet, efficient operation

  • TypeATX
  • Fast wake from sleep with Modern Standby support
  • 80 PLUS Gold certification cuts power draw and heat
  • Fan stops completely at low loads for silent running
  • Resonant LLC topology with DC-to-DC delivers clean, stable power
  • 400 W ATX unit fits standard desktop builds

Modern Standby Power Supply

The KHACHIMO PRT IPC-622 400W unit delivers ATX power with Modern Standby compatibility for extremely fast wake-from-sleep times and improved low-load efficiency. It targets builders who want an 80 PLUS Gold certified supply that runs cooler and quieter in daily use.

Upgrade from basic Bronze units

Replacing an older 80 PLUS Bronze or unrated supply brings higher efficiency, lower power draw and reduced heat output. The jump is worth it when you value near-silent operation at low and medium loads through Zero RPM Fan Mode and cleaner power delivery from the resonant LLC topology with DC-to-DC conversion.

Standard ATX installation

Installation follows the usual ATX mounting pattern and connector layout used in compatible chassis. The main risks are selecting a unit with insufficient wattage for the completed build and overlooking the need for Modern Standby motherboard support to use the fast sleep and wake features.

Domande su questo articolo

What ATX case clearance does the PRM400 require for the 400W unit?

The PRM400 uses a standard ATX form factor, so it fits any chassis with an ATX power supply bay and the usual rear mounting screws.

Which motherboard power connectors must be seated for Modern Standby to work on the IPC-622?

Connect the 24-pin ATX and the 8-pin EPS cables firmly; Modern Standby relies on the DC-to-DC conversion staying active through those rails.

When should the Zero RPM fan be cleaned to keep Gold efficiency on the PRM400?

Vacuum the intake grill once a year; dust buildup forces the fan to spin earlier, raising noise and reducing the 80 PLUS Gold efficiency margin.
