How to Check Power Supply on PC Windows 11 – A Step-by-Step Guide

Checking the power supply on your PC is a crucial task, especially if you’re experiencing issues with your computer. In Windows 11, you can verify your power supply’s health through a few simple steps, without needing to open up your computer case. Let’s dive into how you can ensure your PC’s power supply is functioning correctly.

Step by Step Tutorial: How to Check Power Supply on PC Windows 11

Before we begin, it’s important to note that checking your power supply in Windows 11 will help you understand if it’s working as it should. This can give you peace of mind or help you troubleshoot any potential issues.

Step 1: Open the Start Menu

Click on the Windows icon in the bottom left corner of your screen.

The Start Menu is your gateway to all the applications and settings on your computer. From here, you can access the tool we’ll be using to check your power supply.

Step 2: Search for ‘Power & Sleep Settings’

Type ‘Power & Sleep Settings’ into the search bar and click on the result.

Power & Sleep settings will allow you to adjust how your computer uses power, but it also provides a way to see if your power supply is recognized by your system.

Step 3: Click on ‘Additional Power Settings’

On the right side of the window, you’ll see ‘Related settings.’ Click on ‘Additional power settings’ under this section.

This will take you to the Control Panel, where you can see more detailed power options and information about your power supply.

Step 4: Check for Any Warning Signs

Look for any warning messages or unusual signs in the power options window.

If there are any issues with your power supply, Windows may alert you here. However, it’s important to note that not all power supply issues will be detectable through software.

After completing these steps, you should have a better understanding of whether your power supply is working correctly. If you didn’t find any warning messages, that’s a good sign. However, if you’re still experiencing issues with your computer, it may be worth getting a professional to look at your power supply.
