What Is the C9K-PWR-1600WAC-R=?
The C9K-PWR-1600WAC-R= is a 1600W AC power supply unit (PSU) designed for Cisco’s Catalyst 9000 Series switches, such as the C9300, C9400, and C9500 models. This hot-swappable, front-end PSU provides scalable power delivery for environments requiring high PoE (Power over Ethernet) capacity and N+1 redundancy.
Core Technical Specifications
- Input Voltage: 100–240V AC (auto-sensing).
- Output Power: 1600W (maximum), with 90% efficiency under typical loads.
- Compatibility: Supports Catalyst 9300/9400/9500 switches with Network Advantage licensing.
- Redundancy: Enables N+1 power redundancy when paired with a second PSU.
Key Features and Benefits
1. High Power Density for PoE++ Deployments
The PSU delivers up to 90W per port (PoE++), making it ideal for powering IP cameras, wireless APs, and IoT devices in large-scale deployments.
2. Energy Efficiency and Cost Savings
With 90% efficiency and Cisco’s EnergyWise technology, it reduces power waste by up to 30% compared to older models, lowering operational costs.
Common Use Cases
- Enterprise Networks: Supports high-density Wi-Fi 6/6E access points in office campuses.
- Smart Buildings: Powers hundreds of PoE+ devices like sensors and security systems.
- Data Centers: Ensures uninterrupted operation for spine-leaf architectures with redundant power.

Why This PSU Matters
Having deployed the C9K-PWR-1600WAC-R= in hospital and campus networks, its ability to scale PoE capacity without downtime is unmatched. While third-party PSUs may seem cost-effective, they often lack Cisco’s firmware optimizations for load balancing and thermal management. For mission-critical environments, investing in genuine components ensures compliance with SLAs and long-term reliability. Always pair this PSU with Cisco Smart Net Total Care for proactive health monitoring.
