Server Redundant Power Module 400W

The KHACHIMO MRW-6400P-R is a 400 watt redundant power supply designed for server environments. It uses an ATX form factor to fit compatible chassis and delivers continuous power through hot-swap modules. This unit suits administrators who need fault-tolerant power for critical workloads. Each module is tested working before dispatch.

Replaces failed or ageing server PSUs

Install this module when an existing redundant supply fails or when expanding a chassis that supports the MRW-6400P-R form factor. The jump is worth it if your current unit cannot maintain uptime during a single-module fault. It is not for builds that lack redundant bays or for systems requiring a different wattage rating. Compatibility with your specific server model must be verified before purchase.

Questions about this item

What ATX form-factor dimensions does the MRW-6400P-R module require in the server chassis?

The unit follows the standard ATX power supply form factor, so it fits any server chassis with a matching ATX PSU bay and rear cut-out.

Which step is often missed when installing this redundant 400 W module into a hot-swap cage?

Fully seat the module until the latch clicks, then verify the green AC-OK and DC-OK LEDs on the front panel before assuming the supply is active.
