KHACHIMO 300W ATX power supply 55A 80 PLUS Gold

KHACHIMO 300W ATX Power Supply

The KHACHIMO 300W ATX power supply delivers 55A on the 5V rail for systems that prioritise efficiency and quiet operation. It suits compact or office builds where a high-wattage unit would be unnecessary. The 80 PLUS Gold certification confirms strong energy efficiency across typical loads. Modern Standby compatibility allows near-instant wake times from sleep states.

Build Integration and Space Savings

This unit fits a standard ATX mounting pattern and uses DC-to-DC conversion with a resonant LLC topology to reduce cable clutter from legacy voltage rails. Zero RPM fan mode eliminates fan noise entirely at low and medium loads, freeing the acoustic budget for other components. Clean power delivery supports stable operation of energy-efficient sleep states. The design suits cases where silence matters more than maximum headroom.

Sustained Load Behaviour

Under continuous load the 80 PLUS Gold rating ensures high efficiency, limiting waste heat and keeping internal temperatures lower. The resonant LLC topology maintains tight voltage regulation and reduces coil whine during prolonged use. Zero RPM mode remains inactive once the load exceeds its threshold, engaging active cooling only when needed. The 300W capacity sets a firm ceiling for sustained power draw.
