  3. Monitor the power consumption: Once everything is set up, turn on your PC and let it run normally. The watt meter will display the power consumption in real-time, typically measured in watts. You can monitor the power usage while the computer is idle, during high-intensity tasks, or while running specific applications.

Using a watt meter offers the advantage of providing accurate measurements by directly measuring the power drawn by the PC. This method takes into account not only the power consumption of the components within the PC but also any inefficiencies in the power supply and other external factors. It gives you a more comprehensive understanding of your computer’s actual power usage.

Additionally, watt meters can be used to measure the power consumption of other electronic devices in your home, allowing you to identify energy-hungry appliances and make informed decisions about energy conservation.

Now that you know how to measure power consumption using a watt meter, let’s dive into another approach – estimating power consumption based on individual components.


Estimating Power Consumption of Individual Components

If you’re curious about the power consumption of specific components in your computer, you can estimate their power usage based on their specifications and industry benchmarks. While this method may not provide exact values, it can give you a rough idea of how much power each component consumes. Here’s how you can estimate power consumption for individual components:

  1. Refer to component specifications: Start by looking up the power consumption specifications of your components. Manufacturers often provide power ratings for CPUs, GPUs, motherboards, and other major components.
