The Task Manager provides a quick way to access system performance metrics. You can also right-click the Start menu and select "Task Manager" from the context menu.

Step 2: Navigate to the Performance Tab

Next, click on the "Performance" tab within the Task Manager.

This tab displays various system performance indicators, including CPU, memory, disk, and network usage. It helps you gauge whether your components are being properly powered.

Step 3: Check the Power Usage

Scroll down to the "Power Usage" section.

You’ll see real-time data on how much power each component is consuming. High power usage might indicate that your power supply is strained, especially under heavy loads.

Step 4: Use Windows PowerShell

Open Windows PowerShell by right-clicking the Start menu and selecting "Windows PowerShell."

PowerShell provides advanced system diagnostics. You can type specific commands to retrieve more detailed power supply information.

Step 5: Run a Power Supply Diagnostic Command

In PowerShell, type powercfg /batteryreport and press Enter.

This command generates a detailed report about your system’s power usage and battery (if applicable). The report will be saved as an HTML file, which you can open in any web browser.

Step 6: Review the Generated Report

Locate and open the generated battery report in your web browser.

Review the report for any anomalies or signs of power supply issues. Pay special attention to the "Battery Life Estimates" and "Usage History" sections if applicable.

After completing these steps, you’ll have a clear understanding of your PC’s power supply status. You can then decide if any action is needed, such as upgrading your power supply or tweaking system settings to better manage power consumption.
