KHACHIMO 400W Gold PSU

The KHACHIMO DPS-400CB A is a 400 watt ATX power supply built to the 80 PLUS Gold efficiency standard. It targets system integrators and enthusiasts assembling compact or quiet PCs where reliable power delivery and low noise matter.

Suits quiet, efficiency-focused builds

This unit fits builders who prioritise near-silent operation at idle and reduced electricity draw under typical loads. It is not suited for configurations demanding higher wattage headroom, such as multi-GPU workstations or heavily overclocked systems.

80 PLUS Gold efficiency

The Gold certification verifies high conversion efficiency across representative load points, lowering waste heat and enabling the Zero RPM fan mode to stay inactive longer. This single metric determines whether the PSU matches your thermal and acoustic targets.
