400W ATX Power Supply

The KHACHIMO 400W unit is an ATX form-factor power supply built for desktop PCs that require a Gold-rated efficiency platform. It suits system builders who want certified 80 PLUS Gold performance in a standard footprint without paying for wattage they will not use.

400W capacity and 80 PLUS Gold headroom

The 400W rating delivers enough power for mainstream CPUs and mid-range graphics cards while the Gold certification keeps waste heat and fan noise low. Loads that push toward the maximum limit will reduce the efficiency advantage and cause the fan to spin up, so very high-end components are outside its comfort zone.

Zero RPM fan and LLC topology

A Zero RPM mode stops the fan completely at low and medium loads for near-silent desktop use. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltages and reduces coil whine, while Modern Standby support enables faster wake times and deeper sleep states for everyday productivity.

Questions about this item

Will this 400W ATX unit fit and power an older motherboard that still uses a 24-pin and 4-pin CPU connector?

The 400W ATX design follows the standard connector layout, so it will plug directly into a motherboard with a 24-pin main and 4-pin CPU socket.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the PSU should run cool and quiet; the fan stays off in Zero RPM mode until the load rises past the medium threshold.

Does the package contain the power cord and mounting screws needed for a standard case?

The box includes the PSU unit, an AC power cord, mounting screws and a user manual — no extra parts are required for a typical ATX build.
