KHACHIMO 400W 80 PLUS Gold Power Supply

KHACHIMO 400W Gold PSU

The KHACHIMO 400W unit is an ATX power supply certified to the 80 PLUS Gold efficiency level. It targets system builders who want lower energy draw, reduced heat output and quieter operation in a compact form factor. Modern Standby compatibility ensures rapid wake-from-sleep behaviour for supported platforms. The resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation across varying loads.

Compatibility checklist before purchase

Verify that your chassis accepts a standard ATX power supply and that the physical dimensions match the available space. Confirm that the motherboard power connectors required by your board are present on the unit. Ensure the total system power demand stays within the 400 W rated output. Check that your case airflow can accommodate a unit with a zero-RPM fan mode that relies on passive cooling at low loads.

Integration notes for your build

The fan remains off at low and medium loads, freeing the acoustic budget for other components. Gold-rated efficiency reduces waste heat, easing the burden on case ventilation. DC-to-DC conversion supports modern low-power sleep states without voltage instability. The ATX form factor fits typical desktop enclosures, leaving drive bays and expansion slots unobstructed. Builders needing higher wattage or redundant power should consider a larger capacity unit.
