Cisco PWR-C1-1100WAC 1100W AC Power Supply for 3850 Series - Reliable

Our review of the Cisco PWR-C1-1100WAC focuses on its role as a dependable replacement power supply for the 3850 series. For IT technicians and small datacenter operators who need a tried-and-true AC power module, the biggest reason to consider this unit is its steady, high-capacity output and broad input compatibility. In practical use the module's 1100W capability, compact weight of about 3.09 lbs, and AC input range of 115-240 v make it a straightforward swap into existing 3850 racks, minimizing downtime and preserving system uptime.

Key Features

• 1100W Output: Provides sufficient power headroom for stacked 3850 switches so uptime is maintained under typical loads.
• Wide AC Input: Compatible with 115-240 v AC mains, allowing the same unit to be used in varied regional installations without modification.
• Compact Weight: At about 3.09 lbs the supply is easy to handle during installation and does not add unnecessary bulk to the chassis.
• Config 1 Form Factor: The power module fits the 3850 series mounting and electrical requirements for a direct replacement swap.
• -56 V Output Rail: Delivers the required internal voltage rail expected by the switch, ensuring stable internal power distribution.

Who It's For

The PWR-C1-1100WAC is aimed at network engineers, IT support teams, and small to medium enterprise operations that run Cisco 3850 switches and need a reliable replacement or spare power supply. It is particularly useful where consistent power capacity and compatibility with international AC mains are priorities.

Those who should look elsewhere include users with non-3850 hardware or systems that require hot-swap redundant modules with different wattage or DC-only power configurations. If exact OEM-new packaging or manufacturer warranty is required, purchasers should verify the renewed condition against their procurement standards before buying.

Pros & Cons

Pros

• High output capacity that supports demanding switch loads without obvious strain.
• Broad input voltage compatibility simplifies deployment across sites with different mains voltages.
• Lightweight and compact for an internal power module, easing handling and installation.

Cons

• Renewed condition may mean cosmetic wear and variable warranty terms compared with factory-new units.
