Cisco C3K-PWR-1150WAC= 1,150 W AC Power Supply | Catalyst 3750-E

Keep critical switching hardware in service with the Cisco C3K-PWR-1150WAC= power supply. Designed for Catalyst 3750-E, 3560-E, and RPS 2300 environments, it provides 1,150 W of AC power in a factory-direct replacement format. That matters when you are maintaining production access layers, where power supply compatibility and turnaround time are more important than generic alternatives. This unit is intended for teams that standardize on Cisco switching and need a replacement that matches the platform requirements without guesswork. In enterprise networks, a power supply is not a commodity part when it sits inside a live access switch stack. Choosing the correct OEM supply helps preserve operational continuity, reduce troubleshooting time, and avoid the risk of mismatched hardware during maintenance windows. For procurement and operations teams, the value is straightforward: a purpose-built replacement that supports the installed base, protects uptime, and keeps the network aligned with the original platform design.
