Compact 1U 400W ATX Power Supply

The KHACHIMO P1S-2400V is a 1U form-factor ATX power supply rated at 400W. It is built for compact server chassis or slim workstations where vertical space is limited. The unit is supplied new and has been tested for basic operation.

Suited for 1U rack builds

This supply fits administrators assembling 1U rackmount servers or small-form-factor PCs that accept a 1U ATX unit. Builders needing higher wattage for multi-GPU configurations or extensive drive arrays should look at higher-capacity models instead.

Delivers 400W for typical server workloads

The 400W rating comfortably handles single-socket server boards, a modest number of drives and standard expansion cards. Systems with multiple high-power GPUs or dense storage backplanes will exceed the available headroom.
