400W 1+1 Redundant Server Power Supply

This KHACHIMO unit delivers 400 W of ATX power in a 1+1 redundant configuration for server chassis. It is aimed at operators who need continuous uptime from a hot-swap supply pair. The U1A-F10400-DRB model matches the ASPOWER R1A-FH0400 form factor. Condition is new and each unit is test-working before shipment.

ATX Redundant Supply Practical Limits

The 1+1 architecture means only half the installed capacity is available while both modules run, so total draw must stay within a single 400 W module. Builders who need more than 400 W per node cannot use this supply. The ATX pinout suits standard server boards but will not fit proprietary or high-density blade slots.

Questions about this item

Should I pick the 400 W model or a higher-wattage unit for my server?

Choose the 400 W unit if your system's peak draw stays below that level; the 1+1 redundancy means a second module takes over instantly if the first fails.

What does the 400 W rating mean once the supply is installed in a rack?

It delivers up to 400 W continuously to the motherboard and drives while the paired module stands by, so the server stays running even during a single-module fault.
