What Is the ASR1KX-AC-750W-R=?
The ASR1KX-AC-750W-R= is a Cisco-certified AC power supply module designed for the ASR 1000X router series, providing 750 watts of redundant, high-efficiency power to support critical edge and aggregation network workloads. Tailored for environments requiring uninterrupted operations, this module ensures stable energy delivery for bandwidth-intensive applications like SD-WAN, VPNs, and high-speed data processing.
Key Technical Features and Benefits
- 80 PLUS Platinum efficiency (94%): Reduces energy waste and operational costs, even under full load.
- Hot-swappable redundancy: Enables N+1 power redundancy to eliminate downtime during maintenance or failures.
- Universal input voltage (90-264V AC): Compatible with global power standards, ideal for distributed or backup-powered deployments.
ASR1KX-AC-750W-R= vs DC Power Modules: Critical Differences
| Factor | ASR1KX-AC-750W-R= | DC Power Counterparts |
|---|---|---|
| Deployment Flexibility | Plug-and-play with AC grids | Requires DC battery systems |
| Efficiency at 50% Load | 94% | 88-90% |
| Installation Complexity | Tool-less, 5-minute setup | Complex wiring/cabling |
Addressing Core User Concerns
Q: Is this module backward-compatible with older ASR 1000 chassis?
Yes. It supports ASR 1001-X, 1002-X, and 1006-X routers running Cisco IOS XE 3.18 or later.
Q: How does redundancy work during a power supply failure?
The ASR1KX-AC-750W-R= features automatic load transfer, shifting power demands to the backup unit within milliseconds to maintain uninterrupted service.
Q: Can it handle voltage fluctuations in regions with unstable grids?
Yes. Built-in active power factor correction (PFC) stabilizes input voltage, mitigating risks from surges or brownouts.
Why This Power Supply Stands Out
- SD-WAN readiness: Powers compute-heavy tasks like encryption and deep packet inspection without derating.
- Sustainability: Meets ENERGY STAR® and EU CoC Tier 2 standards, aligning with green IT initiatives.
- Cost efficiency: Reduces cooling needs by 20% through lower heat dissipation compared to legacy units.

On-the-Ground Perspective
During a recent network overhaul for a retail chain, the ASR1KX-AC-750W-R= proved indispensable. While their legacy power modules struggled with holiday traffic spikes, this unit’s adaptive load management prevented overloads, ensuring seamless POS and inventory system operations. For teams prioritizing uptime over flashy specs, this module isn’t just a component—it’s the backbone of operational resilience. In a world where downtime equals lost revenue, investing in robust power isn’t optional; it’s the smartest insurance policy you’ll ever buy.
