The Cisco C9K-PWR-650WAC-R= is an alternate 650W AC power supply unit developed for Cisco Catalyst 9500 Series switches. It shares the same Product ID (PID) as the existing C9K-PWR-650WAC-R and has been fully tested and qualified with Catalyst 9500 Series switches that support a 650W AC PSU. The unit is constructed from durable metal and finished in black and grey.

Advantages

This 650W power supply delivers stable AC power with compatibility across 100–240 V input voltage and 47–63 Hz frequency ranges. It provides a direct replacement option for systems using the C9K-PWR-650WAC-R with the same PID, simplifying inventory and support. The metal housing adds durability and the compact design fits Catalyst 9500 Series switch power bays.
