For many people, determining their power supply unit’s manufacturer, model, and wattage is quite tricky. We’ve figured out the quickest and easiest ways to figure out which PSU your system is using.

We’ll show you how to determine which power supply you have in the following instructions. Methods will cover how to check your power supply with and without removing your side panel, as well as several essential recommendations that will help you make a more educated hardware buy.

What PSU Do You Need?

The power supply unit you purchase must be adequate for your system. Test it to make sure that it is.

Suppose you intend to update your computer components to something more powerful, you should get a power supply with a larger wattage and rated capacity.

Remember that your motherboard and other pricey components may be destroyed if you don’t utilize a top-quality power supply unit.

The best time to assess your power supply is shortly before an upgrade. New generations of hardware or even a same-gen update frequently require a significant amount of more power to function efficiently.

For example, switching from a 2060Ti to a 3060Ti will naturally demand roughly 50-100 extra watts of electricity.

This is often the case with any hardware change, so knowing what you’re working with in terms of watts is critical.

Check out the PSU calculator to see how much watts your new gear will take.

How To Check What PSU I have?

Here’s how to find out the power supply unit you have on your PC:

Power Supply Label

There is a printed layout or a label sticker on every power supply unit with the specs and the model number.

You will simply need to open the PC case and find out the written level on the PSU to verify this label on your PC power supply.

Suppose your power supply is hidden under a PSU cover. In that case, you’ll have to remove it to learn about its specifications and, more importantly, its model number.

To remove your PC’s power supply, you may need to loosen some screws. Before touching your computer, detach it from the power source and switch off the power supply.

Now that you’ve removed your power supply unit, closely examine its body to see whether it has any labels, such as the one seen below.

The certified ratings, model number, and characteristics of your power supply may be found here. This is the quickest and most accurate way to determine the wattage of your power supply.

Check the Manufacturer’s Website

This second method would work only if your computer was bought as a prebuilt.

In this case, the website where you purchased the PC should offer a complete components list that you may use to determine which PSU you have.

This method makes life a lot easier when determining the wattage of your power source. It’s also useful because the power supply on most prebuilt PCs isn’t labeled.

So, search for your computer’s model on the internet. It will verify the wattage of your power supply.

On the Box

You can examine the model and specifications of PSU on the pass apply box if you have it.

Inspecting the power supply’s box is the most straightforward approach to determine the wattage, model number, and other necessary details.

Hopefully, one of the three ways listed above has assisted you in determining what power supply you have.


Finally, the simplest approach to find out what PSU you have is to remove the panel from your chassis. However, we appreciate that not everyone has that privilege; therefore, other options must be considered.

Most people want to know how long does a PSU lasts. Always check your PSU if you want to upgrade, overclock, or make sure it has enough power. It has the potential to save you time, money, and a great deal of worry.

If your PC’s existing power supply is dying, don’t lose time and replace it as soon as feasible.
