Power Supply for Modern Standby Systems

The KHACHIMO DG-120-24 is an ATX power supply designed for builds that require Modern Standby compatibility. It delivers 120W of continuous power at 24V 5A, making it suitable for compact or specialised systems. The unit is brand new and built around a resonant LLC topology with DC-to-DC conversion.

120W Capacity with Gold Efficiency

Rated at 120W, the supply handles typical low-to-mid loads while maintaining 80 PLUS Gold efficiency. This reduces power draw, heat output and acoustic noise across the operating range. Headroom diminishes rapidly beyond the rated wattage, so it is not suited for high-performance GPUs or multi-drive arrays.

Quiet Cooling and Clean Power Delivery

A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. The resonant LLC design with DC-to-DC conversion minimises coil whine and provides stable voltages for efficient sleep states. Builders needing higher wattage or additional connectors should look elsewhere.

Questions about this item

Will the 120W ATX unit power my older motherboard that still uses a 24-pin main connector?

Yes, the DG-120-24 is an ATX-type supply rated at 120W and provides the standard 24-pin main connector used by legacy boards.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the fan remains off thanks to Zero RPM mode, and the unit runs cool and quiet, which reflects the certified Gold-level efficiency in real use.

Does the box include the 24-pin ATX cable and the 4-pin CPU cable, or must I buy them separately?

The power supply ships with all fixed ATX cables attached, including the 24-pin main and 4-pin CPU connectors; no extra cables are required for a standard build.
