How to Check PC Power Consumption in Windows 10

Windows 10 provides several built-in tools and methods to check the power consumption of your PC. Monitoring power consumption can be useful to understand the energy requirements of your computer, optimize power usage, and even calculate electricity costs. In this blog post, we will explore various ways to check PC power consumption in Windows 10.

Using Task Manager

Task Manager in Windows 10 provides a simple way to assess the power usage of your PC. To access the power consumption information, follow these steps:

  1. Right-click on the taskbar and select "Task Manager" from the context menu.
  2. In the Task Manager window, click on the "Processes" tab.
  3. Right-click on the column headers and click on "Select Columns."
  4. In the "Select Columns" window, check the "Power Usage" box and click "OK."
  5. A new column labeled "Power Usage" will appear. This column provides power usage estimates for each running process, displayed in milliwatts.

Using PowerShell

PowerShell is a powerful command-line tool in Windows that can also be used to check power consumption. Here's how:

  1. Press Win + X on your keyboard and select "Windows PowerShell" or "Windows PowerShell (Admin)" from the menu. This will open PowerShell.
  2. In the PowerShell window, type the following command and press Enter:
    Get-CimInstance -ClassName Win32_PowerMeter
  3. PowerShell will display power consumption information, including current power and energy consumption, in watts and joules respectively.

Using Third-Party Software

Additionally, you can use third-party software applications to monitor power consumption. These tools often provide more comprehensive information and additional features. Some popular options include HWMonitor, Open Hardware Monitor, and Joulemeter.


Q: Why should I check PC power consumption?

A: Checking PC power consumption can help you understand the energy usage of your computer and make informed decisions about power optimization. Additionally, it can provide insights for calculating electricity costs and ensuring the stability of your power supply.

Q: Are there any risks involved in monitoring power consumption?

A: No, monitoring power consumption does not pose any risks to your PC or its components. The methods mentioned in this blog post are safe and will not cause any harm if followed correctly.

Q: How often should I monitor power consumption?

A: The frequency of power consumption monitoring depends on your specific needs. If you are troubleshooting power-related issues or conducting energy efficiency experiments, you might want to monitor power consumption more frequently. Otherwise, periodic checks (e.g., once every few months) should be sufficient.

Monitoring power consumption in Windows 10 is a valuable practice to optimize energy usage and understand the electricity requirements of your PC. Whether you use the built-in tools like Task Manager and PowerShell or opt for third-party software, keeping tabs on power consumption can lead to more efficient computing and potential cost savings in the long run.
