Network Routers in Transition: Market Growth and Power Supply Challenges

The rapid evolution of network technologies is placing new demands on router power supply systems:

• Wi-Fi 6/6E/7 Integration:

As LAN and WiFi routers evolve to support Wi-Fi 6, 6E, and 7, they offer faster speeds and enhanced network management. The integration of advanced Wi-Fi standards enables AI-driven optimizations and robust cybersecurity features, simultaneously driving higher power demands that necessitate more resilient PSU designs.

• SD-WAN Adoption:

With the growing implementation of SD-WAN, businesses are turning to flexible, secure edge routers. The surge in SD-WAN adoption demands edge routers with dynamic traffic handling and failover capabilities, requiring PSUs to integrate adaptive load balancing and redundant architectures that sustain network resilience.

• 5G & Core Infrastructure:

Telecom providers and cloud service platforms are expanding data center and backbone infrastructures, driving up energy consumption in core routers. As telecoms scale 5G deployments with denser data traffic, next-gen PSUs leverage high-efficiency modular designs and thermal optimization to mitigate energy waste while aligning with carbon neutrality initiatives.

How much Power does a Network Router consume?

Router Type	Typical Power Consumption
Lan/WiFi Router	5 - 90W
Edge Router	120 - 1000W
Core Router	1000 - 3600W (per module)

Router power consumption depends on the manufacturer and model. However, all routers operate continuously – often under harsh environmental conditions, elevated temperatures, and variable load levels. These factors demand a highly stable and secure power supply.

FSP's industrial-grade power supplies are engineered for continuous operation in networking environments. All FSP power supplies are CE-certified. Selected redundant models feature PMBus-based energy management alongside universal safeguards, including OCP, OTP, and OVP. This multi-tiered protection architecture ensures sustained operational stability for mission-critical routers while supporting eco-conscious operations.

FAQs - Power Supplies for Network Routers

1. How much power does a WiFi router use?

Depending on the manufacturer and model, WiFi routers typically consume between 5 and 90 watts. Since routers operate 24/7, the energy costs add up over time. Using an energy-efficient power supply can significantly reduce consumption and ongoing operating costs in network environments.

2. How much energy cost cana an 80PLUS Titanium power supply save?

Example: FSP2000-20HM with 2000 W, running at 50% load (1000 W):

An 80 PLUS Titanium-rated power supply can save up to 201 € per year compared to a Bronze-rated model, and 69 € compared to a Gold-rated unit. This is based on continuous operation and a German commercial electricity rate of 0.17 €/kWh (as of 2024).

Thanks to lower energy losses, reduced heat generation, and a longer lifespan, an 80 PLUS Titanium power supply ensures efficient energy use in network environments and offers a fast return on investment.
