KHACHIMO 400W 1U PSU for ENH 1940

This KHACHIMO power supply delivers 400 watts in a 1U form factor built for the Enhancement ENH 1940 platform. It uses an ATX design and carries 80PLUS certification for efficient power conversion. The unit is new and has been tested working. It suits system builders who need a direct replacement or spare unit for that specific server chassis.

Capacity and headroom for 400W loads

The 400 watt rating supports typical single-socket server configurations with moderate storage and networking cards. Headroom decreases when multiple high-power GPUs or large drive arrays are added, so the supply may not sustain peak loads in heavily expanded builds. Buyers who need more power headroom for dense GPU deployments or dual high-TDP processors should verify the chassis can accept a higher-wattage 1U alternative. The 80PLUS rating ensures baseline efficiency across normal operating ranges.

Questions about this item

Will this 400 W unit fit and power my existing Enhancement ENH 1940 1U chassis without rewiring?

It is built as a direct replacement for the Enhancement ENH 1940 1U, so the mounting holes, ATX connectors and 400 W output match the original specification.

How do I confirm the 80PLUS-rated supply is operating correctly once installed?

Power on the server, verify the fan spins, and use a multimeter or the system’s built-in sensor read-outs to confirm the main output voltages are present and stable under load.
