Cisco ASR1004-PWR-AC Power Supply | ASR 1000 Series AC PSU UK

Cisco ASR1004-PWR-AC is a Power Supply for ASR 1004 routers. High-capacity 765W AC PSU with hot-swappable design for enterprise and service provider networks. The part number is the reliable way to identify it, because accessories of this kind are often visually identical across generations that are not interchangeable.

Size it for the load, not the box. The common mistake is choosing a supply that covers the chassis and forgetting everything hanging off it. On a PoE switch the powered devices draw through the same supply, and a fully loaded access switch can need several times the chassis figure. Check the input type against the rack, and match airflow direction if a second unit is going in alongside.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Tell us the chassis or model it has to work with and we will confirm the part before anything ships. Quotes go out the same or next working day.
