KHACHIMO 400W ATX Power Supply

The KHACHIMO 400W ATX power supply delivers 400 watts of continuous power for standard desktop builds. It suits office workstations, home PCs and entry-level gaming rigs that do not demand high-wattage headroom. Builders seeking an efficient, quiet unit for modest hardware will find it a practical choice.

Build Quality and Connectors

The unit carries 80 PLUS Gold certification, indicating high efficiency that reduces heat output and lowers electricity draw. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltages while minimising coil whine. A zero RPM fan mode stops the fan completely at low and medium loads, providing near-silent operation during everyday tasks. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Upgrade Path and Value

This supply replaces older, less efficient units that lack Gold-rated performance or advanced sleep-state support. The jump is worthwhile when moving from a basic bronze or unrated PSU to gain quieter running, lower energy costs and Modern Standby readiness. It is not for systems requiring more than 400 watts or builds needing multiple high-power GPU connectors.

  • 80 PLUS Gold certification cuts power draw and heat
