The power supply provides energy to all components in a computer system. Knowing its specifications helps determine if it’s powerful enough, plan upgrades, and troubleshoot issues. Finding what power supply you have without opening the computer case can be challenging, but it can be done through different methods.
- There are several methods for finding out the specifications of your power supply without opening the computer case. Checking the documentation and labeling is one of the simplest methods for finding your power supply specifications.
- You can find the specifications of your power supply through the PC manufacturer’s website or by contacting the manufacturer’s support team.
- Another way to find the type of power supply in your computer is by looking for the PSU label. If the information on the PSU label is unclear, you can look for the Underwriters Laboratories (UL) label, a third-party company that certifies power supply products for safety.

There are several methods how to find out the power supply you have without opening the computer case. Mostly used methods are given below with details and specifications. Also, make sure to read about how to check insufficient power supply.
Check Documentation And Labelling
Checking the documentation and labeling is one of the simplest methods how to find out power supply specifications without opening the computer case. Here are the steps to follow:
Step 1: Locate the manual or documentation with your computer or power supply. The manual is usually a printed document that comes in the box with your computer or power supply. It might also be accessible as a PDF file on the manufacturer’s website.
Step 2: Research the power supply’s information. Your computer’s parts, including the power supply, should be described in the manual. Look for a section titled “System Configuration” or “Power Supply.”
Step 3: Check the specifications listed in the manual. This information should include the make and model of the power supply, its maximum power output, voltage information, and other technical specifications.
Step 4: Make a note of the information you find. Write down the make and model of the power supply, its maximum power output, and other relevant information. This information will be helpful when looking for replacement parts or upgrades.
Step 5: Check the exterior of your computer for labels or stickers.

This information may also be listed on a label or sticker near the power supply.

Step 3: Once you have found the specifications, look for information about the power supply. This information will probably include the power supply, voltage, and amperage values your computer works on.
Step 4: Check the warranty if you still cannot find the information. The warranty information should have the specifications of the power supply. If the power supply is under warranty, it is advisable to contact the manufacturer’s support team to obtain the information.
Step 5: If you still cannot find the information, contacting the manufacturer’s support team may be necessary. The support team will be able to provide you with the information you need, including the type of power supply, voltage, and amperage.
Finding By PSU Label
To find out the type of power supply in your computer, you can look for the PSU label. It is situated close to where the power cord meets the case on the back or side of your computer. If it’s not easily accessible, you can use your phone’s camera. The label should have information such as the watt’s capacity, voltage, amps, and brand.
If the information is unclear, you can look for the Underwriters Laboratories (UL) label, a third-party company that certifies power supply products for safety.
