Compact 1U Server Power Supply

The KHACHIMO DPS-400AB-12C is a 400W ATX switching unit built to the 1U form factor. It targets rackmount servers, compact workstations and embedded appliances that require a slim, high-efficiency power source. The Modern Standby compatible design ensures extremely fast wake-from-sleep times and better low-load efficiency.

Integration and Cable Management

The unit mounts in a standard 1U bay and delivers up to 400W through an ATX connector set. Its resonant LLC topology with DC-to-DC conversion provides clean, consistent power to modern components while enabling more energy efficient sleep states. This topology also reduces coil whine for quieter overall system operation.

Thermals, Noise and Efficiency

80 PLUS Gold certification confirms high efficiency operation for lower power consumption, less noise and cooler temperatures. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads, delivering near-silent operation. The combination of efficient conversion and intelligent fan control keeps thermal output minimal during normal use.
