- The power supply unit (PSU) is a crucial component of any PC, powering all other components.
- Knowing the specifications of your PSU is important for optimal system configuration.
- There are three different ways to determine what power supply you have: checking the model number online, using the ‘About This Mac’ feature for Macbooks, or physically inspecting the power supply inside your computer case.
One of the most crucial parts of any PC is the power supply unit (PSU). Simply put, nothing functions properly without it.
If you’re trying to figure out if your system has the optimal configuration, knowing the precise specifications of your PSU can be helpful. But, it doesn’t directly communicate with the motherboard like the GPU and the CPU.
So, it’s a challenge to evaluate it, but it’s not impossible. Here’s how to see what power supply you have in three different ways.
What is a Power Supply?
A power supply is a specialized component. It typically resides inside your PC and powers all of the other components. It may be external, where you’ll have an old power brick that needs to be plugged in. Or it could be inside the case and plastic or metal with a fan. Because there are many different types of power supply components, they come in varying sizes.
The importance of your power supply unit is often overlooked in favor of the more eye-catching parts. But it’s crucial to know how much power you have, especially if you use your computer for heavy gaming or similar tasks.
Because of this, we’re listing three different ways to figure out what power supply you have.
How to See What Power Supply You Have
Whether you purchased a pre-built PC, or laptop, or plan on building your own, there are many different ways to figure out your power supply.
Let’s break down each method!
Method #1: Steps to Follow if You Have a Prebuilt Desktop
Step 1: Find Your PCs Model Number
First, take a look at your computer. You can typically find the PC model number on the back or bottom of the tower case. Usually, there is a sticker on the back.
Step 2: Enter the Model Number Online
Once you have your model number, simply Google it and it should pull up the manufacturer’s website. From there, you can choose your computer and search for the PSU specifications listed.
If you can’t do it this way, simply try to type in the make and model of the computer you have. Many forums and online sources can help you figure out your model number and the power supply.
Method #2: What to Do if You Have a Macbook
If you have a laptop, it’s still fairly easy to find what PSU you have. To find the model number of a regular laptop, you should be able to use the steps we’ve mentioned previously. But instead of having the model number on the back or side, it will most likely be at the bottom of your laptop.
However, if you have a Macbook, there is another way to find your power supply information.
Step 1: Go to About This Mac
First, click on the Apple icon at the top left-hand corner of your computer. Then, select About This Mac.
Step 2: Look Up the Power Supply
Next, click System Report at the bottom section of About This Mac and it will pull up all of the information you need to know about your laptop.
From there, you can find the power supply information by clicking Power on the left-hand side.
Method #3: Checking the Power Supply Physically
If the above options don’t work for you and you’re still unable to find the information you need, you can check for it physically. Here’s how.
Step 1: Power off Everything
First, you’ll want to power off your computer. Once that’s complete, unplug all of the wires, including your power cord.
Step 2: Open Your Case
Once everything has been powered off, you’ll need to unclip or unscrew your side panel to open your case. How you open the panel will depend on your computer’s make and manufacturer, but it should be fairly easy to do.
Step 3: Find the Power Supply
Now that you’ve opened the case, the power supply should be visible. It’s usually near your power cord’s port, and it will almost always have a sticker on it to show its specs. If it doesn’t have the sticker, this may mean that yours did not come from a reliable manufacturer or it got peeled off somehow.
There are many factors to consider when figuring out your power source. It needs to be constructed well, provide the power you need, and deliver that power the right way to your device.
Even though it can be simple to locate your power supply data, there may be a time when you need to physically open your computer. While that may seem intimidating, as long as you treat your computer carefully, it should all work out fine!
