KHACHIMO 1U DPS-400AB-12B 400W 500W power supply

1U 400W Gold PSU for Modern Standby Systems

This new 1U power supply delivers a rated 400W with a 500W peak rating and carries 80 PLUS Gold efficiency certification. It is built for compact servers and workstations that require reliable DC-to-DC conversion and low-load efficiency. The unit supports Modern Standby for rapid wake-from-sleep behaviour in compatible platforms. Its resonant LLC topology helps reduce coil whine while maintaining stable output.

Ideal for 1U builds needing silent low-load

The Zero RPM fan mode stops the fan completely at low and medium loads, making this unit suitable for noise-sensitive rack or desktop deployments. Builds that demand sustained output above 400W or require a standard ATX form factor should consider alternative units. The 1U height restricts use to chassis designed for this slim profile. Systems without Modern Standby support will not benefit from the fast wake capability.

Rated 400W with 500W peak capacity

The single specification that determines fit is the continuous 400W rating paired with a 500W peak limit. Verify that your total system draw stays within the rated figure for sustained workloads. The peak headroom handles brief transients but is not a continuous rating. Match this number to your component power budget before purchase.
