300W ATX power supply for modern standby

The KHACHIMO unit delivers 300 watts through a standard ATX form factor and carries 80 PLUS Gold certification for high-efficiency operation. It is designed for systems that use modern standby sleep states and need fast wake times.

Zero RPM fan mode and resonant LLC topology

At low and medium loads the cooling fan stops completely for near-silent running. The resonant LLC design with DC-to-DC conversion supplies clean power, reduces coil whine and supports deeper energy-efficient sleep states.

Practical limits of the 300W ATX interface

The 300 watt rating restricts use to platforms with modest power draw and cannot support high-end graphics cards or multiple heavy drives. Builders needing more headroom for overclocking or dense storage arrays will find the capacity insufficient.

  • Fast wake from sleep with Modern Standby support
  • High efficiency cuts power draw with 80 PLUS Gold
  • Fan stops at low load for silent running

Questions about this item

Will the cooling fan ever need replacement after long-term use?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing wear and extending the fan's service life.

What limits continuous output when the unit runs at full load?

The 300 W rated capacity is the maximum sustained power the supply can deliver.

How much noise and heat should I expect during all-day operation?

80 PLUS Gold efficiency and Zero RPM Fan Mode keep noise near zero at typical loads and reduce waste heat.
