1U 400W ATX Power Supply for Compact Servers

This 1U form-factor ATX unit delivers 400 W of continuous power for rack-mount servers and space-constrained workstations. It targets system integrators who need reliable, high-efficiency power in a single rack-unit height. The Gold-certified design keeps waste heat low in dense enclosures.

400 W Capacity with 80 PLUS Gold Efficiency

At full load the supply provides 400 W while maintaining 80 PLUS Gold efficiency, reducing electricity draw and thermal output. Headroom is sufficient for multi-core CPUs, several storage drives and a single mid-range GPU. Builds requiring dual high-end GPUs or extreme overclocking headroom will exceed the available wattage.

1U Form Factor with Zero RPM Fan Mode

The 1U chassis fits standard server racks and shallow cases without additional brackets. Resonant LLC topology with DC-to-DC conversion delivers stable rails and supports Modern Standby sleep states. Zero RPM mode stops the fan at low and medium loads for silent operation. Builders needing ATX cable lengths for full-tower cases should verify reach before installation.
