450W ATX Power Supply

The KHACHIMO YM-2451P is a 450 watt ATX power supply built for desktop systems that prioritise efficiency and quiet operation. It suits mainstream builds where moderate power draw meets a demand for low noise.

80 PLUS Gold Certified

This unit carries 80 PLUS Gold certification, delivering high efficiency across typical loads to reduce waste heat and keep electricity costs down. The rating is the primary indicator that the PSU matches your efficiency target.

Resonant LLC Topology with DC-to-DC Conversion

Resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery during sustained workloads while suppressing coil whine. Zero RPM fan mode keeps the fan stopped at low and medium loads, so acoustic output stays minimal even during extended sessions. Modern Standby compatibility enables faster wake-from-sleep and deeper low-power states.
