The Dell PowerEdge R320 and R420 servers require a power supply unit (PSU) with a power rating of 550 watts. The Dell RYMG6 and M95X4 are both part numbers for the same 550W power supply unit that is specifically designed for use in these servers.
The RYMG6/M95X4 PSU is a hot-swappable, redundant PSU that is designed to ensure the continued operation of the server even if one PSU fails. It is capable of providing reliable and stable power to the various components of the server, including the CPU, memory, storage devices, and other peripherals.
This PSU comes equipped with all the necessary cables and connectors to connect to the various components inside the server, and it features an efficient and stable power delivery system that is compatible with Energy Star and 80 PLUS certification standards.
It also features various safety and protection mechanisms, including over-voltage, over-current, and short-circuit protection, to ensure the safety of the server and its components. The hot-swappable design of the PSU means that it can be replaced without shutting down the server, which helps to ensure minimal downtime.
