Cisco Power Supply

The efficiency of a power supply is determined by the fact that how much AC (or, in some cases, DC) input power is required to give rise to a given amount of power output. For instance, a power supply that requires 200 watts of input power to provide 180 watts of output power would provide an efficiency of 90% as a ratio of output power to the input power (180/200 = 0.9).

The 20-watt difference between the input and output (10% percent of power) would be lost in the form of heat dissipation due to resistance. Apart from losing electricity in the form of heat, this waste in energy comes amidst another negative aspect of inefficient power supplies, that is; you’ll need a cooling mechanism onboard to send this heat to the sink before it starts causing any trouble to your hardware components.

Of course, the efficiency of a Cisco power supply isn’t linear or flat when it comes to the PSU’s output range. Most Cisco power supply units showcase their maximum efficiency while performing at the maximum limit. It means that a 1000-watt power supply providing 600 watts of power will show 60% efficiency. It will be less efficient than an 800-watt power supply providing the same 600 watts of output power (75% capacity). It means the same amount of output power but different efficiencies.

Why does this matter?

When choosing a Cisco power supply, efficiency is an important aspect but in order to accurately estimate the power consumption of your server system, it is recommended a power supply that can easily adjust within your server rack and will run at optimal efficiency.

For enterprise-grade data centers, significant energy dissipation from multiple servers running poor-quality and low-grade power supplies can heavily impact the cost of running these servers.

Cisco Server Performance And Power Supply Efficiency

Choosing a power-efficient Cisco power supply can save you a lot of annual expenditure.

When it comes to setting up a server for your facility, there are a lot of aspects to ponder over. One of the crucial parts that you’ll need to consider as a primary component of your server system is a power supply. Cisco Power Supply is one of the options available in the market to power your Cisco router, and other Cisco products in your networking infrastructure.

Cisco Power Supply Efficiency

Generally speaking, the more efficient a power supply is, the less power your Cisco router or switches will consume overall. If you’re having multiple servers together in a rack, the savings in electricity units will have a significant compound impact at the end of the year.

Titanium power supplies are the most efficient option with 96% power efficiency due to the smaller coefficient of friction. Whereas, Platinum power supplies show a slightly low efficiency of 94% and Gold power supplies offer 92% efficiency.
