General power supply rules are as follows:
Minimum of 1 and maximum of 2 power supplies per system.
If 2 are installed, power supplies must be identical.
Important:
It is highly recommended to validate server configuration for specific power requirements using the
latest version of the System x Power Configurator:

This will ensure that the right power supply is chosen for optimal performance.
