300W ATX power supply

This KHACHIMO unit delivers 300 watts of continuous power in a standard ATX form factor. It targets builders assembling office PCs, home-theatre systems or compact workstations that demand quiet, efficient operation.

Fits standard ATX cases

The supply slides into any chassis with an ATX power-supply bay and connects to a 24-pin motherboard header plus the CPU and peripheral cables your build requires. Its Zero RPM fan mode stops the fan at low and medium loads, freeing the system from audible noise during typical desktop tasks.

Modern Standby and 80 PLUS Gold

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and deeper low-power states. The 80 PLUS Gold rating confirms high efficiency across the load range, reducing waste heat and supporting the fan-less behaviour at lighter loads.
