  • Tested working and built with good-quality components

Redundant 300 W ATX supply for IPC systems

This KHACHIMO unit delivers a 1+1 redundant 300 W ATX power solution built for industrial PC chassis. The R1S2-5300V4V and P1S-2300V-R modules combine to keep the system running if one supply fails. It is intended for integrators who need continuous uptime in rackmount or embedded deployments. The supply ships new and has been tested working.

Thermals noise and power draw in normal use

Under typical load the redundant pair shares current, so each module runs below its 300 W rating and stays cool with moderate fan speed. Acoustic output remains low enough for server-room environments. The design draws only what the connected components require, avoiding unnecessary overhead. No efficiency certification or thermal specification is provided in the data.

Questions about this item

How do I install the 1+1 redundant 300W PSU and what step is often missed?

Slide both hot-swap modules into the chassis until they click, then connect each module to separate AC circuits; the step often missed is wiring the second feed so true redundancy works.

What maintenance will the R1S2-5300V4V P1S-2300V-R need later?

Clean the intake fans every few months and replace a failed module by pulling the release latch and inserting a matching 300W unit without powering down the system.
