KHACHIMO PRM400 400W ATX power supply

SKU CH-QM0S-B80DA

A 400 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for fast wake times

  • TypeATX
  • Modern Standby support for rapid wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency, lower power draw, less noise and cooler temperatures
  • Zero RPM fan mode stops the 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
  • Designed for the PRT IPC-622 chassis with a 400 W ATX form factor

Built for PRT IPC-622 Chassis

This 400W ATX power supply is designed specifically for the PRT IPC-622 enclosure. It suits builders who need a compact, efficient unit that matches the original form factor and power budget of that industrial platform.

80 PLUS Gold Efficiency

The single specification that decides fit is the 80 PLUS Gold certification. It guarantees high efficiency across typical loads, reducing waste heat and lowering operating cost for systems that run continuously.

Modern Standby and Quiet Operation

Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency. Zero RPM fan mode keeps the unit silent at low and medium loads, while resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Perguntas sobre este artigo

What does the 400W rating mean for a real build?

It is the maximum continuous DC output the unit can deliver to your components, so the total power draw of CPU, GPU, drives and fans should stay below that figure.

What does the 80 PLUS Gold certification actually limit?

It guarantees the supply meets strict efficiency targets at typical loads, which cuts waste heat and lets the fan remain idle more often.

Will this unit fit the IPC-622 chassis?

Yes, the PRM400 is built specifically for the PRT IPC-622 case and uses the standard ATX form factor for that enclosure.
