1U 400W ATX PSU for Rack Builds

This KHACHIMO unit fits a standard 1U rackmount chassis and delivers 400 watts of continuous power. It targets system integrators and home-lab builders who need a compact, reliable supply for always-on servers or workstations. The new condition guarantees full component life from day one.

80 PLUS Gold Efficiency Decides Fit

The 80 PLUS Gold certification confirms high efficiency across typical loads, reducing wasted energy and heat inside dense enclosures. If your project demands that efficiency tier for thermal headroom or electricity cost targets, this supply meets it; if a lower tier suffices, a cheaper unit may be adequate.

Zero RPM Fan and LLC Topology for Quiet Operation

A Zero RPM mode stops the fan completely at low and medium loads, enabling near-silent operation during idle or light tasks. The resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports modern standby states for fast wake times and cooler running temperatures.

Questions sur cet article

What does the 400W rating mean when the unit is installed in a 1U server chassis?

It delivers up to 400 W of continuous power in the compact 1U form factor, supporting Modern Standby for fast wake and efficient low-load operation.

How does the 80 PLUS Gold certification affect efficiency and noise in this supply?

Gold certification means high efficiency across typical loads, which reduces heat and lets the Zero RPM fan mode stay off longer for near-silent running.

What physical space and mounting does this ATX supply need in a rack?

It fits a standard 1U rack slot using the ATX mounting pattern, so it installs directly into compatible server chassis without adapters.
