Redundant 550W ATX power supply

The KHACHIMO M1Z2-5550V3V is a 550W ATX unit with 1+1 redundant architecture. It targets server and workstation builders who need continuous uptime from a single-slot form factor. Each module can sustain the full load independently.

Hot-swap modules maintain power during replacement

The bundled hot-swap trays let technicians exchange a failed module without shutting down the system. Redundancy is preserved throughout the swap, protecting critical workloads from interruption.

Questions about this item

How often should the hot-swap fan modules be replaced in the 550W redundant unit?

The power supply uses a 1+1 redundant design with hot-swappable modules; each module contains its own cooling fan, so a single fan failure only requires swapping the affected module rather than the whole unit.

What protects the 5550 series supply if both modules run at full load continuously?

Each 550W module includes over-current and over-temperature protection that will throttle or shut down the module before components exceed safe limits, while the second module maintains power to the system.
