KHACHIMO DPS-400AB-12F 1U 400W 80plus Gold power supply

1U 400W 80 PLUS Gold Power Supply

The KHACHIMO DPS-400AB-12F is a 1U form-factor ATX power supply rated at 400W. It targets system integrators and builders assembling compact servers or workstations where rack height is restricted. The unit carries 80 PLUS Gold certification for high efficiency across typical loads. It is not suited for builds that require higher wattage headroom or full-size ATX dimensions.

Compact Build Integration

The 1U chassis fits directly into standard rackmount enclosures and shallow-depth cases designed for slim power supplies. Its ATX connector layout supports modern motherboards while the DC-to-DC conversion topology simplifies voltage regulation on the secondary side. Modern Standby compatibility enables faster wake-from-sleep transitions for supported platforms. Builders needing redundant power modules or larger cable bundles should verify chassis clearance before ordering.

Sustained Load Behaviour

Under continuous operation the resonant LLC topology delivers clean, consistent power with reduced coil whine. The Zero RPM fan mode keeps the cooling fan stationary at low and medium loads, cutting acoustic output during idle or background tasks. 80 PLUS Gold efficiency lowers waste heat, helping internal temperatures stay stable during extended duty cycles. The supply lacks active fan control at higher loads, so airflow management in the host enclosure remains critical.
