Cisco PWR-C5-1KWAC — 1000W Configurable AC Power Supply
What it is
PWR-C5-1KWAC is a Cisco configurable AC power supply that delivers 1000 watts of AC power to supported Cisco switches, modular systems, and other chassis that accept Config-5 PSUs.
It’s designed for reliable, high-capacity power delivery with hot-swappable capability and can be used as either a primary power supply or part of a redundant PSU configuration in enterprise and data-center environments.
Why buyers pick PWR-C5-1KWAC (plain English)
High-capacity power delivery
1000 watts of output supports larger systems, PoE-enabled switches, and higher-density deployments without throttling performance.
Configurable flexibility
Built for platforms that allow you to choose power modules based on your required capacity and redundancy strategy — letting you scale power to match your hardware and workload.
Supports redundancy
Install this PSU alongside others (where supported) to create a redundant power system so the device stays powered even if one supply fails — boosting uptime.
Hot-swappable design
Can be inserted or replaced while the device is running (for supported platforms), reducing maintenance windows and avoiding downtime.
Cisco-qualified reliability
Engineered and tested for compatible Cisco systems to ensure predictable performance and supportability in enterprise networks.

Modular PSU
Use case
Primary or redundant AC power for enterprise switches and modular chassis with higher power demands.
Where it fits (and when to choose something else)
Perfect for:
-
Enterprise access/distribution switches with PoE/PoE+ demands
-
Modular systems needing flexible, high-capacity PSU choices
-
Redundant power configurations for improved uptime
-
Deployments with high-density modules and line cards
Choose something else if:
-
You need even higher capacity → 1200W / 1600W / other larger PSUs
-
You need DC power → Config-5 DC PSU alternatives (if supported)
-
Your platform uses fixed PSUs → platform-specific fixed unit
TL;DR
PWR-C5-1KWAC is Cisco’s 1000W configurable AC power supply:
a hot-swappable, high-capacity PSU for enterprise switches and modular systems built to handle heavier power and redundancy demands.
