500W 2U Redundant Server Supply

The KHACHIMO YM-5501A is a 500W ATX power supply designed for 2U server and storage chassis. It provides redundant operation so a second module can take over if the primary unit fails. The 80PLUS rating confirms baseline efficiency for continuous enterprise workloads.

Replaces Failed or Non-Redundant Units

This supply replaces a failed module in an existing redundant pair or upgrades a single non-redundant unit to a fault-tolerant configuration. The jump is worth it when uptime requirements demand immediate failover without shutting down the server. It is not for builds that lack a compatible 2U redundant backplane or for systems needing a different wattage or form factor.

Highlights

  • 500 W output powers 2U server and storage systems
  • 80PLUS certification reduces energy waste and operating cost
  • Redundant design keeps equipment running if one module fails
  • Tested working and built with good quality components

Questions about this item

Will this 2U redundant PSU fit my standard ATX chassis?

The unit follows the ATX form factor and is built for 2U server storage bays, so it fits those mounts but not standard desktop ATX cases.

How do I install the YM-5501A and what step is often missed?

Slide the module into the 2U bay until the latch clicks, then seat both power cables; the step most people miss is engaging the redundant hot-swap latch fully.
