KHACHIMO EPR-305 300W Redundant Power Supply

Redundant 300W ATX Power Supply

The KHACHIMO EPR-305 is a 300 watt redundant power supply built to the ATX form factor. It targets system builders and IT professionals who need continuous uptime for servers or critical workstations. The unit is supplied new and has been tested working by the manufacturer.

Redundancy limits and ATX constraints

Redundant operation protects against a single module failure, but total output remains capped at 300 watts across all rails. The ATX form factor fits standard chassis cutouts, yet the internal redundancy hardware reduces the power density compared to a single non-redundant unit of the same size. Cable routing and airflow must accommodate the extra module bulk.

Capacity headroom for typical loads

A 300 watt budget comfortably handles entry-level server boards, low-power CPUs and a modest complement of drives or add-in cards. Headroom shrinks quickly when multiple high-draw GPUs, large drive arrays or power-hungry processors are added. Builders planning heavy expandability should calculate peak draw carefully before committing to this capacity.
