550 W power supply for x3650 M4 server

This replacement unit fits the Lenovo x3650 M4 chassis and delivers 550 W of continuous output. It matches part numbers 94Y6668, 94Y8074, 94Y8075 and 94Y8064 for direct compatibility. The supply is new and ready for immediate installation in a supported server.

Capacity and headroom

The 550 W rating covers typical dual-processor configurations with standard memory and storage complements. Systems heavily populated with high-wattage CPUs, many drives or multiple GPU accelerators may exceed the available headroom. Builders needing redundant power or higher single-unit capacity should verify their total load before purchasing.

Questions about this item

Will this 550W unit fit alongside the existing components in my x3650m4 chassis?

It is built for the x3650m4 and matches part numbers 94Y6668, 94Y8074, 94Y8075 and 94Y8064, so it aligns with the original mounting points and power connectors.

How can I confirm the 550W supply is operating correctly after installation?

The server should power on without error LEDs, the management controller will report the PSU as present and healthy, and the system fans will spin at normal idle speeds.
