How to Check Power Supply On PC Windows 10


Checking the power supply of a Windows 10 PC is a quick and easy process. There are two ways to do this, one is by using the power button on the PC and the other is by going through Settings.

There are two ways to check if your power supply is working correctly on Windows 10. One way is to use the Power button on your PC, while another way is to go through Settings. The first option can be found in Control Panel as well as in the Power and Sleep menu that appears when you right-click on your desktop.

The first thing to do is to power off the PC. Turn the PC on its side and look for a small hole next to the power supply.

You can use a paper clip or a needle to poke inside this hole and see if there is any power running through it. If there is no power, you need to check your cables and make sure they are all connected properly.

If they are, you need to replace your power supply.

Method Two

First, open the Task Manager by right-clicking your taskbar and selecting “Task Manager,” or by pressing Ctrl+Shift+Esc. If you don’t see the full Task Manager pane, click “More Details” at the bottom.


How do You Check Your PC Power Supply?



This information appears on the Processes pane but is hidden by the small size of the window. For you to know how to check the power supply on windows 10, you need to Enlarge the window by clicking and dragging at the corner until you see the Power Usage and Power Usage Trend columns, or scroll to the right. You can also drag and drop the headings to reorder the list of columns.

If you don’t see these columns, right-click the headings here and enable the “Power Usage” and “Power Usage Trend” columns. If these options don’t appear in the list, you haven’t upgraded to the October 2018 Update yet.

Each process has a value under these columns. The Power Usage column tells you how much power the process is using at this exact moment, while the Power Usage Trend column shows you the longer-term trend. You can click the columns to sort by either type of power usage.

For example, a process might currently not be using much power at this very moment, but might be using a lot of power in general. Or, a process might be using a lot of power right now, but it tends to use very little power. Focus on the trend for a better idea of how much power a process uses.

Unfortunately, Windows doesn’t give you precise numbers here. It just gives you a rough idea of power usage, which should be “Very Low” for most processes on your system. If a process is using more power than that—especially if it’s running in the background—you may want to quit that process to save battery power on your laptop or tablet.

Microsoft hasn’t explained exactly what the various words here mean. We don’t know the precise difference between “Very low” and “Low. How to check power supply wattage without opening PC will be explained here in the Nine steps below. Look at the exposed faces of the power supply unit for a sticker or label that describes the unit’s electrical capacities.

This label is required to be placed on all ATX form factor computer power supplies. It will designate how many amps are available for each voltage type and give a “watts max” designation.

  • Step 1

Unplug your case from any electrical source and press the power button for 10 seconds to ensure any stored electrical charge is dissipated.

  • Step 2

Remove the thumbscrews from the rear face of the case that holds the computer’s side access panel in place, and pull the side access panel back with light force to remove it from the case.

  • Step 3

Locate your power supply within your case. It will be located against the rear wall of the case, either at the very top or the very bottom.

  • Step 4

Use light force to slide your power supply forward toward the front of your case where your hard drives and optical drives are located.

  • Step 5

Pull your now semi-free power supply outward away from the case. Take care not to pull too hard or fast, because all your components are still connected to your power supply.

  • Step 6

Manipulate the drive and check every face for a specifications label. Once you find it, check the wattage rating as explained in step 5 of the previous section.

  • Step 7

Reposition your power supply into its original position, and remount it with the four mounting screws you removed earlier.

  • Step 8

Replace the female plug removed earlier from the rear of the power supply back into place.

  • Step 9

Reassemble the case as detailed in steps 6 and 7 of the previous section.

What is Power Supply Calculator


In this section, you’ll learn what a power supply calculator means, how it works, and many more.

If you’re new to PC building, the chances are, your knowledge of components wattage is going to be fairly limited. Using a PSU calculator is going to take any of the stress that comes with choosing the right PSU away from the build process.

It not only recommends the required wattage for your build but also offers up some of the best PSU options for each specific price point. The PSU calculator really does make your life a whole lot easier.


How Your PSU Can Affect Gaming Performance



The most important components in a gaming PC are the CPU and GPU. But these components, just like all the others, need adequate power to operate. If your power supply can only provide 80% of the power your GPU needs, it can’t just simply run at 80% performance. Instead, the system will be unable to run at all and will likely crash.

So, if you’re working with a PSU that can’t support the rest of your build, all that hard work you put into building your gaming PC will be for nothing.

But, that’s not all. If you’re working with an unstable power supply, you run the risk of damaging your components permanently. That’s why we always recommend choosing a PSU that has a higher efficiency rating.


Upgrading Your PSU


One thing to remember, as, with all PC components, you can always choose to upgrade your PSU. If you ever choose to upgrade your GPU, upgrading your PSU should be a priority too. You need to make sure you’re giving your GPU as much power as it needs to run properly, and you might even need to provide more PCIe power connections than your current PSU can provide – depending on the model.

But, don’t worry, upgrading your PSU is fairly simple and it can help you on how to check the power supply on pc windows 10.


You just need a screwdriver, some cable-management love, and patience. If our PSU calculator has told you that you need to upgrade, then all you need to do is follow these simple steps.

  1. Shut off power to your PC and remove the power cord
  2. Remove the side panel of your PC case to gain access to all the technical goodies inside
  3. Remove all PSU power cables and connections from your components
  4. Remove any other components that are obstructing your access to the PSU
  5. Remove the screws on the back of the PC that attach the power supply to the case and remove the entire power supply unit
  6. Once you’ve safely disposed of your old PSU, place your new, upgraded PSU into position
  7. Screw your new PSU in and put back any other removed components
  8. Reattach all the power cables so your PSU is properly installed
  9. Power on your PC to check all the connections are working
  10. Turn your PC back off, reattach the side panel and enjoy your new PC build
