Pc Power Supply

PSU stands for Power Supply Unit, and it is one of the most important components of a PC. It powers your PC’s components, such as the motherboard, GPU, and hard disk drive. In many scenarios, you may need to know the model and the specifications of the PSU.

For instance, you may want to check the specifications of your PSU to know if it allows you to add more components to your PC and provide sufficient power to overclock them.

Quick Answer

In a nutshell, the PSU of your PC is placed within the computer cabinet or case, and you need to open the case to locate the power supply unit. Opening the case is easy as all you need to do is unscrew a few screws.

Additionally, there’s one more easy way to check the specifications of the PSU of a PC. This method requires you to search for your PC model on the web and get PSU details from there.

Here, in this blog post, we will guide you on how to check your PC’s power supply unit. We will discuss two different methods specified above and share with you the steps that you need to follow for fulfilling your objective, i.e., to get the details of the PSU that your PC has. So, let’s get started!

Method #1: Inspect the PSU Label Physically

To proceed with this method, you will need a screwdriver to open the screws on the case so that you can access the components placed inside.

Warning

Before you make physical contact with the case, it’s essential that you shut down your PC and unplug it from the main power source.

Now, you simply need to follow the steps mentioned below:

  1. Unplug your PC from the main power supply.
  2. Remove the power cord as well as other cables attached to the case.
  3. Now, you need to look for the screws that hold the case’s side panel.
  4. In general, the power cord attached to the case indicates the position of the PSU. So, you simply need to locate the port where the power cord attaches and look exactly to the back of the port, inside the case.
  5. You will be able to see a big box, which is the power supply unit.
  6. Finally, it’s time to look for the information about the PSU that is usually printed on the label attached to the PSU itself. In general, the information that you can find on the label includes the following:
    • Name and Model.
    • Voltage.
    • Wattage.
    • Max. Current.
    • Max. Voltage.
    • Total Power.

If you cannot find details other than the name and model of the PSU, you can search the web for the PSU using its name and model and get more details about it.

Method #2: Search on the Web

This is yet another effective method for finding information about the PSU of your PC. However, this method works successfully if you have a pre-built PC and not a custom one.

Below are the steps that you need to follow to get information about the power supply unit of your PC:

  1. Find the model name and number of your PC that can be mentioned on a label or printed on the hardware (usually on the cabinet or case).
  2. Now, you need to open a web browser on your PC.
  3. The best way to proceed is to visit the manufacturer’s official website and find your PC model there.
  4. Alternatively, you can search for the PC directly on the web using a search engine like Google and Bing. However, make sure you visit a reputed website to get the details of your PC.
  5. At last, when you can see your device details either on the manufacturer’s website or a third-party website, you need to look for the device’s specifications.
  6. You will be able to get details about the power supply unit.

While this method is easy, it cannot guarantee that the details you get are completely correct. So, it’s advisable to do a physical inspection to get accurate details of your PC’s power supply unit.

Conclusion

It’s quite an easy task to check the PSU on a PC, and all you need is to leverage one of the methods mentioned above. However, we want to put more weight on the first method, i.e., inspecting the PSU label physically, as it ensures that you get precise details of the PSU.
