Modern Standby Support

This KHACHIMO YM-2651R unit delivers 650 watts through a standard ATX form factor. It targets desktop builders who want efficient power delivery with quiet operation and compatibility for modern sleep states.

80 PLUS Gold Efficiency

The Gold certification confirms high efficiency across typical loads, which reduces power draw, heat output and fan noise. Builders who need to meet strict efficiency targets or minimise running costs will find this rating decisive.

Zero RPM Fan Mode

At low and medium loads the cooling fan stops completely, removing audible noise during office work or media playback. Systems that run heavy sustained loads will still spin the fan, so silence is not guaranteed in every scenario.
