Replacement for RN4220 Server

This 550W ATX unit is a direct replacement power supply for the RN4220 server. It matches the DPS-550LB E specification and is built for continuous NAS operation. The unit is sold new and tested working before dispatch. It suits administrators restoring a failed server or keeping a cold spare on hand.

Simple ATX swap with model check

Installation follows standard ATX mounting and connector routing inside the server chassis. The main risk is ordering the wrong revision; verify the DPS-550LB E part number on the original unit before purchase. No extra cables or adapters are included beyond what the original design provides. Builders needing redundant or higher-wattage configurations should look elsewhere.
