DELL 1100 Watt power supply. Tested and compatible with many 13 and 14gen DELL servers. Be sure not to mix power supplies of different part numbers.
The DELL 1100W 80 Plus Platinum 0CMPGM is a server-grade hot-plug power supply unit (PSU) used in Dell PowerEdge enterprise systems.
Here’s what that part means in practical terms:
It is a 1100-watt AC power supply designed to deliver stable, high-capacity power for demanding Dell servers. The 80 Plus Platinum rating means it is highly energy efficient (typically ~90%+ efficiency under common loads), which reduces heat output and power waste—important in data centers where multiple PSUs run continuously.
The 0CMPGM (also written CMPGM) is the Dell part number identifier for this specific PSU model. Dell often assigns multiple part numbers to similar or revised versions of the same power supply.
Key characteristics of this unit:
Hot-plug / hot-swappable: It can be removed and replaced without shutting down the server (if redundant PSUs are installed).
Redundant PSU support: Often used in pairs so one can fail without downtime.
Designed for PowerEdge servers such as R630, R730, R740, T-series servers, etc.
86mm server PSU form factor, not a standard ATX desktop power supply.
Built for 24/7 enterprise workloads, with strong cooling and reliability rather than quiet operation.
