Cisco PWR-C6-125WAC — 125W Configurable AC Power Supply
What it is
PWR-C6-125WAC is a Cisco configurable AC power supply that delivers 125 watts of power to compatible Cisco network devices. It’s designed as a modular, hot-swappable PSU for systems that support multiple power supply options, letting you provide basic AC power or build redundancy depending on your device’s configuration and power requirements.
Why buyers pick PWR-C6-125WAC (plain English)
Right-sized for lower draw devices
125W output is well-matched for small switches, routers, or devices with modest power needs — especially where PoE isn’t required or only minimal power is needed.
Configurable flexibility
Built for platforms that allow you to choose between PSU options. You can start with this power supply and later add another for redundancy or higher total capacity.
Hot-swappable design
Can be installed or replaced while the system is running (on platforms that support hot-swap PSUs), helping reduce service disruptions.
Supports redundancy
Where the hardware supports multiple PSUs, you can pair two units for failover/backup power to increase uptime.
Cisco-qualified reliability
Engineered and tested for Cisco platforms that accept Config-6 PSUs to ensure dependable power delivery and supportability.

Use case
Basic AC power for low-power Cisco devices; part of a redundant PSU configuration.
Where it fits (and when to choose something else)
Perfect for:
-
Small Cisco switches and routers with Config-6 PSU bays
-
Environments with modest power requirements
-
Redundant designs where multiple smaller PSUs are used instead of a single large one
-
IO/field appliances or compact networks
Choose something else if:
-
You need higher capacity → 300W / 600W / 1000W Config-6 PSUs
-
You need DC power → DC-rated PSUs where supported
-
Your platform uses fixed internal PSUs → fixed PSU models
TL;DR
PWR-C6-125WAC is Cisco’s 125W configurable AC power supply:
a compact, hot-swappable PSU that delivers basic AC power to compatible Cisco devices and fits environments with low power demands or redundancy requirements.
