Power supply units
The power supply unit (PSU) is an internal hardware component which supplies power to the components in the system.
CAUTION:
The PSUs must have the Extended Power Performance (EPP) label. Mixing PSUs (even the PSUs that have the same
power rating) from previous generations of PowerEdge servers is not supported. Mixing PSUs results in a PSU mismatch
condition or failure to turn the system on.
Your system supports two 2400 W, 2000 W, or 1600 W AC PSUs.
NOTE:
For more information, see the Technical specifications
section.
