KHACHIMO 400W ATX Power Supply PWR-CH1-400WAC

400W ATX power supply for efficient builds

This KHACHIMO unit delivers 400 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery and supports energy-efficient sleep states.

Suitable for mainstream desktops and office systems

This supply suits builders who want quiet operation at low and medium loads thanks to its Zero RPM fan mode. The design reduces coil whine for a quieter computing experience. It is not intended for systems that require more than 400 watts of power. Builders planning high-end multi-GPU configurations or heavily overclocked components should look at higher-wattage units.

80 PLUS Gold efficiency rating

The 80 PLUS Gold certification confirms high efficiency operation, which lowers power consumption and reduces heat output. This efficiency level contributes to cooler temperatures and less fan noise under typical workloads. Resonant LLC topology with DC-to-DC conversion further supports stable voltage regulation. Choose this specification when energy efficiency and quiet low-load operation are priorities.
