Modern Standby Ready ATX Unit

This KHACHIMO power supply delivers 400 W of continuous power from a 24 V input using a standard ATX form factor. It targets system builders who need reliable energy conversion for workstations or industrial PCs that run 24/7. The unit is new and carries 80 PLUS Gold certification for high efficiency across typical load ranges.

Suited For Quiet, Efficient Sleep States

The resonant LLC topology with DC-to-DC conversion supplies clean power while enabling deep, low-consumption sleep states compatible with Modern Standby. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Builders who require redundant power inputs or higher wattage headroom for multi-GPU configurations should consider other options.

24 V Input Defines Compatibility

The single specification that decides fitment is the 24 V input voltage; the unit will only operate from a 24 V DC source. Verify that your chassis or power distribution board provides this exact input before purchase. All other features depend on this electrical match.
