KHACHIMO ATX 5 V 25 W Unit

This KHACHIMO ATX power supply delivers 5 V at 4 A for a total of 25 W, making it suitable for low-power builds or specialised auxiliary rails. It is intended for users who need a compact, high-efficiency source rather than a mainstream system PSU.

Sustained Load Behaviour

The 80 PLUS Gold rating ensures high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower during continuous operation. Zero RPM fan mode keeps the cooler off at low and medium loads, while resonant LLC topology with DC-to-DC conversion maintains clean, stable output without coil whine.

Deciding Specification

The 5 V 4 A 25 W output rating is the single figure that determines whether this unit matches the device or rail you are powering. Buyers who require higher wattage or additional voltage rails must select a different power supply.

Questions about this item

How quiet is the 25 W unit when it runs all day under light loads?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so the 25 W supply operates silently for most of the day.

Does the ATX 5 V 4 A connector need any extra cables or adapters to fit my motherboard?

It uses a standard ATX pin-out, so the 5 V 4 A output plugs straight into a compatible motherboard without extra adapters.

Will this 80 PLUS Gold supply work reliably with an older ATX motherboard that lacks Modern Standby support?

Yes, the resonant LLC topology with DC-to-DC conversion delivers clean power to legacy boards, though Modern Standby fast-wake benefits will not be available.
