PSU configuration

Refer to the following section for more information on the PSU configurations.

PSU support matrix

Validate the power requirements for your configuration using the latest version of the Power Configurator to ensure that the number of power supplies selected are adequate for supporting your chassis configuration. The Power Configurator tool can be found at Lenovo Capacity Planner website.

CAUTION

Failure to validate the configuration with the Power Configurator tool could result in system errors, failure to power on, or microprocessor throttling, and limiting system's ability to leverage all the microprocessor performance.

Note

The tables below are based on nodes with all DIMM slots, PCIe slots, and hard disk drives populated.
