550 W Redundant Supply for PowerEdge R320

This Dell power supply delivers 550 W of redundant power to the PowerEdge R320 server. It is built as a hot-plug module so a failed unit can be swapped without shutting the system down. The part carries manufacturer numbers 1J45G, RYMG6 and M95X4 and weighs 5.0000 LBS. It arrives new and is covered by a 90 day warranty.

Suited for R320 redundancy; not for other servers

The unit fits administrators who need a direct replacement or a second module to complete a redundant pair in a PowerEdge R320. It will not suit operators of other Dell server models or anyone requiring a different wattage or form factor. Buyers needing non-redundant desktop power supplies should look elsewhere.

Hot-plug module frees a bay and uptime

The supply slides into the server’s dedicated redundant bay and connects to the internal power distribution board. Its hot-plug design lets technicians replace a module while the R320 stays online, preserving uptime and freeing the second bay for the matching unit. No extra cabling or adapters are required beyond what the chassis provides.

Questions about this item

Which Dell PowerEdge server models accept the 550W redundant power supply with part numbers 1J45G, RYMG6 and M95X4?

This supply is built for the Dell PowerEdge R320 and fits the server's redundant power bay without modification.

Can I run this 550W unit alongside an older Dell power supply of a different wattage in the same R320 chassis?

Redundant operation requires matching wattage; mixing a 550W module with a different-rated supply will prevent the redundancy feature from functioning.

After installation, how do I confirm the 550W redundant supply is active and healthy in the R320?

Check the iDRAC or front-panel LEDs — both power-supply indicators should show steady green, and the system event log must report no power-supply faults.
