Compact 1U ATX Power Supply

The KHACHIMO DPS-400AB-17B is a new 1U form-factor ATX power supply rated at 400W with a 500W peak capacity. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for extremely fast wake-from-sleep times and better low-load efficiency.

Suited for Space-Constrained Builds

This unit fits small 1U chassis and systems that value quiet operation, thanks to a Zero RPM fan mode that stops the fan at low and medium loads. Builders who need higher continuous wattage or a standard ATX height unit should look at something else.

Build Integration and Cabling

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine and enabling efficient sleep states. The design frees up vertical space in compact enclosures and lowers overall system noise and temperatures.

Domande su questo articolo

Does my motherboard need a 24-pin ATX connector for this 400 W unit?

Yes, the power supply uses the standard ATX form factor and requires a 24-pin motherboard connector to operate.

Will the -12 V rail on this PSU support legacy ISA cards I still use?

The -12 V output is rated for the small currents needed by older ISA expansion cards and compatible motherboards.

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

Check that the system reports Modern Standby wake times and that the fan remains off at low load, indicating Gold-level efficiency.
