Knowing what PSU you have is an essential step in upgrading your computer. It’s not always clear what PSU you have right off the bat, either, especially if you bought your PC as a pre-assembled unit instead of building it yourself. Fortunately, there are some ways to figure out what PSU you have, even if you aren’t sure what it is initially.

How Do I Find My PSU?
Unlike some of the other internal components of your computer, you can’t find out your PSU’s make and model by running the Device Manager. Unfortunately, this means you do need to pry open your computer case to figure it out. Fortunately, on many computer models, your PSU may be in a separate compartment, making it easy to isolate it and look.
However, while this is a general rule, some more expensive power supply units are made with intelligent hubs built-in. These PSUs let you monitor fans and other parts of your rig, such as your GPU, through programs loaded onto your computer. However, most people will still have to look inside their PC to see what PSU they have.
When you first open your PC case, you should be able to tell visually whether your PSU is modular, semi-modular, or non-modular. This is an important thing to note, as some PSU models will come in multiple variations and varieties.
Additionally, most PSUs will have a large sticker on one side (usually the bottom) that has all of its specs listed, as well as relevant information like the model and serial numbers. While it’s not the easiest to access them when they’re in your computer case – you might want to take a picture or take notes so you don’t have to look inside when you need the information – they’re always right there if you need the info.
Additionally, those with pre-assembled PCs may have one other option at their disposal. If you can find the serial number or make and model of your PC, you might be able to identify the PSU that way. If you can track down the specifications of your individual computer online, such as from the manufacturer’s website, you might be able to track down your particular PSU from there.
