Power supply units
The power supply unit (PSU) is an internal hardware component which supplies power
to the components in the system.
Your system supports two 750 W Mixed Mode HVDC PSUs.
If two PSUs are installed, both the PSUs must have the same type of label. For
example, Extended Power Performance (EPP) label. Mixing PSUs from previous
generations of PowerEdge servers is not supported, even if the PSUs have the
same power rating. Mixing PSUs will result in mismatch condition or failure to
turn the system on.
