KHACHIMO 300W ATX Power Supply

The KHACHIMO AT With Switch P8P9 is a 300W ATX power supply built for desktop PCs. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for fast wake times. A Zero RPM fan mode stops the fan at low and medium loads for silent running. Resonant LLC topology with DC-to-DC conversion delivers stable voltage and reduces coil whine.

Suits builds needing efficient 300W ATX power

This unit fits standard ATX cases where a Gold-rated 300W supply meets the system draw. It suits users who value low-load efficiency and near-silent idle operation. Builds requiring higher wattage, modular cabling, or non-ATX form factors should look at other units. Systems with peak loads above the rated output need a larger capacity supply.

300W rated output decides fit

The single specification that determines compatibility is the 300W continuous power rating. Total system power draw under load must stay within this limit. The 80 PLUS Gold badge confirms high efficiency across typical loads. No other single figure in the data governs whether this supply powers a given build.
