Cisco UCSC-PSU-450W enterprise networking (router/Catalyst switch/UCS families) Power Supply

The Cisco UCSC-PSU-450W is a 450-watt hot-swappable power supply built for the Cisco UCS C-Series family of rack-mount servers. C-Series servers such as the C220 and C240 M-generation models take one or two supplies of this class depending on configuration, with a second unit providing N+1 redundancy so the server keeps running through a single supply failure. It is sized for the lower end of the C-Series power envelope, suiting entry to mid-range configurations rather than servers fitted with multiple high-draw GPUs or a full complement of high-power CPUs, which typically call for the higher-wattage supplies in the same family. UCS C-Series servers remain widely deployed both standalone and as UCS Manager-integrated rack servers alongside B-Series blade chassis, and a spare power supply is a routine stock item for anyone maintaining a fleet of them. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
