ATX Power Supply for Modern Standby PCs

The KHACHIMO MH-300N-24VB is an ATX power supply built for systems that require Modern Standby support. It delivers 300 W across 12 V and 24 V rails to power compatible desktop components. The unit is 80 PLUS Gold certified for high efficiency during typical workloads. Its design targets builders who want low-noise operation in a standard form factor.

Efficiency and Noise Limits at Low Loads

The 80 PLUS Gold rating guarantees at least 80 percent efficiency at defined load points, reducing waste heat and fan demand. Zero RPM mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and minimises coil whine. These features work best when the system stays within the supply's rated capacity.

Check Connectors and Standby Requirements

Verify that your motherboard and components accept the 12 V and 24 V outputs provided by this unit. Confirm the ATX connector layout matches your board's main power and CPU power headers. Ensure the platform supports Modern Standby to use the fast wake and low-load efficiency features. This supply will not suit builds needing higher wattage or different voltage rails.
