C9K-PWR-650WAC-R Description
C9K-PWR-650WAC-R is a Cisco Catalyst 9500 Series High Performance 650W AC power supply module for C9500-32QC, C9500-48Y4C, and C9500-24Y4C switches, used as the installed or redundant PSU in core and aggregation deployments where these platforms need Cisco-supported AC input power. Cisco documents this field-replaceable, hot-swappable module as a 650W AC supply with a 90 to 264 VAC, 47 to 63 Hz input range, an IEC 60320 C14 receptacle with a 10A cord rating, and support for the 2-slot power design that keeps a blank cover in any unused slot to maintain chassis airflow.

Application Scenarios
C9K-PWR-650WAC-R fits a replacement or spare-pool plan for C9500-32QC, C9500-48Y4C, and C9500-24Y4C switches that already use the Cisco 650W AC PSU family.
The Catalyst 9500 chassis supports one installed power supply with a blank cover in the other slot, or two installed supplies for redundancy. This SKU is suitable when the second bay must match the 650W AC PSU table entry.
Projects comparing C9K-PWR-650WAC-R and C9K-PWR-650WACL-R should separate the two PIDs by the Cisco-listed surge, hold-up, and over-power protection differences instead of treating the names as interchangeable.

- In a C9K-PWR-650WAC-R vs C9K-PWR-650WACL-R comparison, both PIDs are 650W AC Catalyst 9500 power supplies for the same listed high-performance switch models.
- The C9K-PWR-650WAC-R difference from C9K-PWR-650WACL-R is not wattage or input connector; the table differences are surge rating, AC line hold-up time, and over-power protection value.
- For buyers comparing C9K-PWR-650WAC-R vs C9K-PWR-650WACL-R, the which model to choose decision should follow the exact PID required by the BOM and any regional power-supply rule attached to the deployment. C9K-PWR-930WDC-R is included as an additional same-family comparison point.
Selection Guide
1. Match the supported switch family first
Choose C9K-PWR-650WAC-R only for the Catalyst 9500 High Performance models Cisco maps to the 650W PSU family: C9500-32QC, C9500-48Y4C, and C9500-24Y4C.
2. Keep AC input and cord details visible
Confirm that the site feed matches the 90 to 264 VAC, 47 to 63 Hz input range and that the purchase line includes the correct IEC 60320 C14 power-cord plan.
3. Avoid cross-family substitutions
Do not replace this SKU with a 1600W C9500-32C PSU or a 950W C9500-16X PSU, because Cisco maps those power supplies to different Catalyst 9500 hardware.
4. Separate the WACL-R variant deliberately
Select C9K-PWR-650WACL-R only when the order requires that exact 650W AC variant; the two 650W PIDs have different surge, hold-up, and over-power protection entries.
