How to find out your power supply

Everyone wants their PC to be optimized, whether they use it for work or for enjoyment, and the power supply of your PC is crucial to how well it runs. You risk experiencing how to find out your power supply severe system crashes and malfunctions if your computer does not have sufficient power to run all of its components.

Therefore, you must ensure that your computer’s power supply is adequate before upgrading it, for example, by installing a cutting-edge graphics card that consumes more power but increases your frames per second. Sadly, inspecting your power supply is more difficult than other jobs. Instead of using an app, you’ll need to open your PC’s case and examine the power supply in person. 

Examine the Label to find power supply

Reading the printed label on the PSU by opening your PC case is one of the finest methods. The brand name, wattage, voltage, and current rating of your power supply are all located here. The ampere and voltage values are written in small letters, while the computer infoz and wattage are display in bold. You must take into account the voltage and maximum current ratings in addition to the wattage when choosing your power supply unit (PSU) for installing a new GPU in your computer. If you can’t locate the label on your PSU, it’s time to try the alternative approach. 

What if I can’t see the tag on the power supply?

UL (formerly called Underwriters Laboratories) mandates that all power supplies come with a sticker with power ratings on it. If your power supply doesn’t have a sticker identifying it, it can be on a side that you can’t see. If this is the situation,how to find out your power supply where you must take out the power source before you can locate it. The following section of this page includes links to supplementary material that lists the procedures for doing so.

1. Physically inspect the PSU.

You should be aware of the PSU’s specifications in advance if you constructed your own computer and it wasn’t purchased pre-made. However, if it’s a pre-built PC, you might not be aware of the power supply you have. Because its only function is to provide power to the computer components, power supplies don’t interface with motherboards.

Through your computer’s interface, there is no way to find out what PSU you have. Physically inspecting your power source is the simplest approach to determine it. Depending on the manufacturer, each PC offers information about the PSU within the chassis in a different area. To locate the PSU, you must open the side panel of the computer case and look for a label or sticker on the side or at the top. 

2. Online Lookup

If you have a pre-built PC but don’t want to open your case, this method is really useful. You can visit the manufacturer’s website, type in your PC’s model number, and search for the PSU specifications listed there. The best option is to open the case and physically inspect the PSU because manufacturers occasionally alter its specifications and features for future iterations of the same model. But not all manufacturers offer this information, so you might not discover it on some of their official websites. It also helps to Google the make and model of your PC and look up the power supply’s specifications on reputable sources. 

3.User Guide

If you have a pre-built computer, you can check the user guide to see what kind of power supply you have. The manufacturer provides a complete list of specifications. If it doesn’t, you can check up the PSU’s model number and use it to conduct a web search for further information. 

How is PSU wattage measured?

Here are two quick techniques to measure your power supply unit’s wattage. Verify the PSU Side Label. The PSU is often located at the bottom and back of the case compartment. However, the label is accessible from either side of the PSU. In order to reach it, you might have to open the PC casing. The PSU wattage may be visible from the outside if your CPU case has translucent side panels.

However, you must take it off how to find out your power supply to reach the PSU if your side panel is opaque or if you can’t read the labels because your side panel is tinted.  If it is difficult for you to access the PSU, use the methods listed below to gain access to it and measure its wattage. 

1 .Open the Side Panel

Make sure you have disconnected the PC from a wall outlet before beginning. Additionally, hold down the power button for between five and ten seconds to discharge any capacitors that may have accumulated charge. Unscrew any screws keeping the side panel in place that are located on the CPU case’s back or side. Use a metal tray, as advised, to guard against losing the screws. The panel should secure by three to five screws. After you have taken out all the screws, carefully remove the panel by sliding it outward or removing it at an angle. 

Unscrew any screws keeping the side panel in place that are located on the CPU case’s back or side. Use a metal tray, as advised, to guard against losing the screws. The panel should be secure by three to five screws. After you have taken out all the screws, carefully remove the panel by sliding it outward or removing it at an angle. On the other side, repeat the same procedure. Once one panel is remove, you can see the complete motherboard, while the other panel reveals a compartment where all the cables are kept. 

2. Search for the PSU

The back top or back bottom side of the PC chassis is often where the power supply is housed. Find a rectangular cuboid on the case compartment’s back side. Because of its size, the PSU will be difficult to ignore. From the back of the PC chassis, you can also see where the PSU is located. A switch for the PSU is located on the back of the chassis. To find the PSU, look for this switch on the back of the chassis. Once you’ve found the PSU, look for labels that have been written on it. On either side, look for writing. 

You must disconnect every cable connecting the PSU to the motherboard, SSDs, HDDs, disc drives, and GPUs in order to remove it. Remove the cord that joins the wall outlet and PSU as well. After you remove all the linked wires, the PSU should now be accessible. Once all the cables have been disconnected, remove any screws holding the PSU in place. To reach the PSU label, now slide the PSU outward. 

3. Check the PSU label

The bold digits that represent your PSU’s wattage will follow by the word W. For illustration, 550W, 650W, etc. The name of the product, the model number, the voltage, the maximum power, the maximum current, and the total power are also listed on the label. An approved PSU will display an approved rating such as 80 Plus gold, bronze, silver, or platinum. Consult the user guide. You can consult the system’s user manual if you are using a pre-built system and don’t want to deal with the trouble of pulling the PC apart to read the PC label. The PC’s instruction manual will contain all the information about its parts.
