Cisco Refurbished Power Supplies
Need a replacement power supply for your Cisco switch, router, or server? We stock refurbished Cisco power supplies for switches, routers, servers, and other rack-mounted infrastructure — PoE power supplies for access points, and everything in between, from small adapters up to 8,700W chassis power supplies for large service provider systems. Every unit is tested before it ships, so you get the same reliability as new, at a much lower cost.
Power supplies are exact-fit components, so we stock genuine Cisco OEM part numbers across the full product range — Catalyst, Nexus, UCS, ASR, ISR, ASA, Firepower, and more — rather than generic third-party replacements. Depending on the platform, our stock includes both single and redundant power supply configurations. If you know your existing part number, that's the fastest way to find the right match.

- 300+ Cisco power supply models — from small adapters to 8,700W chassis units
- Every unit inspected and tested under our ISO 9001-certified quality management system
- Redundant and single-PSU configurations available

Find the Right Power Supply by Part Number
Cisco power supplies aren't universally interchangeable, even when wattage and connectors appear similar. The safest way to find a compatible replacement is to match the Cisco part number from your existing PSU. Not sure which one you need? Talk to our team and we'll help you match it to your system.
Extend the Life of Your Cisco Infrastructure
Replacing a failed power supply can keep existing Cisco hardware in service without replacing the entire system. For infrastructure that's approaching or beyond OEM support, Third Party Maintenance services provide ongoing hardware support to help extend equipment life further.
Frequently Asked Questions
What is a Cisco power supply unit (PSU)? A Cisco power supply unit is the component that powers a Cisco switch, router, server, or other device — available as a rack power supply for chassis-based systems, or a smaller adapter for compact devices.
How do I find the right power supply for my system? The most reliable way is to match the exact Cisco part number from your existing unit. If you're not sure what you need, our team can help you identify the right match.
Are all Cisco power supplies interchangeable? No. Cisco power supplies are designed for specific systems and product families, and units with similar wattages aren't necessarily compatible. Check the Cisco part number and supported system before ordering.
How much can I save with a refurbished power supply? Refurbished units typically run up to 80% below the price of new hardware, depending on the model and wattage.
Are refurbished power supplies tested before shipping? Yes — every unit is tested before shipping under our ISO 9001-certified quality management system.
