Redundant 549 W ATX power supply

This KHACHIMO unit delivers 549 W through a redundant ATX design that keeps a system running if one module fails. It suits servers and workstations that cannot tolerate unexpected shutdowns. The supply has been tested and confirmed working before shipment.

Thermals, noise and power draw

Redundant sharing lets each module operate at lower load, which typically reduces fan speed and acoustic output during normal operation. Efficiency at typical loads keeps waste heat and overall power draw in check for continuous service.

Highlights

  • Redundant 549W output keeps systems running
  • ATX form factor fits standard server chassis
  • Tested working ensures reliable operation
  • Compatible with R1IA2551A and R2IS7551A part numbers

Questions about this item

How is the KHACHIMO 549W redundant power supply installed and what step is often missed?

Mount the unit in a standard ATX chassis, connect the 24-pin motherboard cable and the CPU power cable, then ensure both redundant modules are fully seated and latched so the fail-over circuit is active.

What maintenance or replacement will the KHACHIMO R1IA2551A R2IS7551A need later?

Clean the intake vents and fan blades every six to twelve months; if a module fails, replace only that module with an identical 549W redundant unit to keep the hot-swap redundancy working.
