800 W ATX Power Supply

The KHACHIMO MX104 DC delivers 800 watts through an ATX form factor and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables rapid wake-from-sleep and improved low-load performance, making it suitable for contemporary desktop builds that demand responsive power management.

Standard ATX Installation

Mounting follows the regular ATX pattern so it fits typical chassis cut-outs and screw positions. The DC-to-DC resonant LLC topology simplifies internal cabling by converting voltage on the secondary side, while the Zero RPM fan mode eliminates noise at low and medium loads. Installers should verify that case clearance accommodates the unit depth and that all required power connectors reach their destinations without strain.

Builders Seeking Efficient Quiet Power

This unit suits system integrators and enthusiasts who prioritise gold-level efficiency, silent operation at idle and Modern Standby support. Users needing higher wattage, redundant supplies or non-ATX form factors should consider other options.
