New ATX Power Supply

This KHACHIMO unit is a new ATX power supply rated at 750 W. It is built for desktop builders who need a modern, efficient unit that supports current sleep states. The design targets systems where low idle noise and fast wake times matter.

80 PLUS Gold Efficiency

The single specification that decides fit is the 80 PLUS Gold certification. It guarantees high efficiency across typical loads, which reduces power draw, heat output and fan noise. Systems that run long hours benefit most from this efficiency level.

Zero RPM Fan Mode Under Load

At low and medium loads the cooling fan stops completely, delivering near-silent operation. Resonant LLC topology with DC-to-DC conversion keeps voltage stable and suppresses coil whine during sustained use. Modern Standby compatibility ensures fast wake-from-sleep without power spikes.
