720 W ATX power supply

This KHACHIMO unit delivers 720 W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable output. Modern Standby compatibility enables faster wake-from-sleep transitions and improved low-load efficiency.

Suitable for quiet, efficient desktop builds

The zero-RPM fan mode stops the fan completely at low and medium loads, making it a good fit for systems where acoustic output matters. Builds that require higher wattage headroom or specific modular cable configurations not described here should consider other options.

80 PLUS Gold efficiency rating

This single specification confirms the supply meets strict efficiency targets across typical operating loads, reducing waste heat and overall power draw. If your build demands a different efficiency tier or lacks space for a standard ATX unit, this model will not match those requirements.
