KHACHIMO 375W ATX Power Supply M1Z-6375P3

375W ATX Power Supply for Modern Standby PCs

The KHACHIMO M1Z-6375P3 delivers 375W of continuous power in a standard ATX form factor. It is built for systems that rely on Modern Standby for instant wake times and improved low-load efficiency. This unit suits office workstations, compact builds or upgrade projects where a lower-wattage, high-efficiency supply is preferred. It is not for buyers who need more headroom for discrete graphics cards or heavy multi-rail loads.

Sustained load efficiency and thermal behaviour

Certified to 80 PLUS Gold, the supply maintains high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during extended sessions. Resonant LLC topology with DC-to-DC conversion provides clean, consistent voltage regulation under continuous demand. The Zero RPM fan mode stays active through low and medium loads, eliminating fan noise entirely until higher thermal thresholds are reached. This combination supports quiet, stable operation during long workdays or background tasks.

Build quality, connectors and daily implications

The resonant LLC and DC-to-DC design reduces coil whine, contributing to a quieter environment even when the fan spins up. Modern Standby compatibility enables deeper, more energy-efficient sleep states without compatibility issues. Standard ATX mounting ensures straightforward installation in compatible chassis. The unit is not for builders who require modular cabling or additional PCIe connectors beyond what a 375W design typically provides.
