KHACHIMO MD1120 485W ATX Power Supply

485W ATX Power Supply for Modern Standby Builds

This KHACHIMO unit delivers 485 watts of continuous power through an ATX form factor suited to mainstream desktop builds. It targets system integrators and upgraders who need reliable efficiency and fast wake-from-sleep behaviour without over-provisioning wattage. The 80 PLUS Gold rating confirms high efficiency across typical load ranges. Modern Standby compatibility ensures the platform enters and exits low-power states quickly.

Fits Standard ATX Cases and Frees Acoustic Headroom

The supply mounts in any chassis with a standard ATX PSU cut-out and uses a single cooling fan that stops completely at low and medium loads. Zero RPM Fan Mode removes fan noise during office work or media playback, leaving only component noise from the rest of the build. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight, reducing coil whine that can distract in quiet rooms. Clean power output also supports deeper sleep states for the whole platform.

Gold Efficiency Lowers Heat

At 80 PLUS Gold efficiency the unit wastes less energy as heat, so case temperatures stay lower and the fan remains off longer. When the fan does spin, the resonant LLC design minimises audible switching noise. The combination of high efficiency, fan-off operation and reduced coil whine makes the supply practically inaudible under typical desktop workloads. Power draw from the wall scales closely with actual system demand.
