How To Find Out What Power Supply You Have?

You risk experiencing severe system failures and malfunctions if your pc doesn’t have adequate power to operate all its elements. Let us know ‘How To Find Out What Power Supply You Have?’.

How To Find Out What Power Supply You Have?

Therefore, you must ensure that your computer’s power source is good enough before upgrading it—for example, by installing a cutting-edge video card that consumes more power but increases your frames-per-second rate.

However, inspecting your power supply is more trickish than other operations. Instead of using an application, you’ll need to unlock your computer’s casing and assess the power supply in person.

Find out what power supply you have?

Many computer owners are curious about their motherboards, Graphics, and processors. Many people also wish to understand what kind of power source they have.

The prerequisites to know this usually comes up while updating the computer or introducing a new graphics card. A person must thus be aware of how to verify their power supply gadget.

Unlocking your PC case and looking at the model and characteristics of the power supply tagged on the casing or identified on a label on the PSU is the most practical approach to verify the PSU on your computer. Additionally, you can assess the PSU case that comes along.

What does a PSU do?

You may lack an appropriate technical background and are unsure of the relevance of power supply components. What makes a PSU so unique, and why is it such an essential element of my computer? It’s all right; this article helps you understand it so you can cope with any practicable PSU issues you could have.

As their name indicates, power supply units do more than provide power for your computer. In addition, and more intrinsically, a PSU’s role is to control the Electrical output to the exact limits required by your system and turn intermittent power line current (AC) into dc supply (DC).

It maintains everything in your computer running smoothly, so when it doesn’t operate properly, it becomes a significant issue.

The Current output voltages cannot be effectively monitored by a Power Supply Unit that is not working. Long-term effects include efficiency issues, hard-to-predict blackouts, and, in the worst situation, catastrophic harm to essential computer elements like the chipset and CPU. You must regularly track the efficiency of your PSU to prevent this.

Process of Examining the computer’s power source

Verify the PSU Tag

Insurers Research facilities mandate that all power supplies have a tag that states their rated power. A power supply will always have a label decal or printed design with the PSU product code and characteristics.

You must unscrew the computer case and search for the printed value on the power supply unit (PSU) to verify this display.

If your power source is protected by a PSU cowl, you will need to remove the power supply to learn more about its specifications and brand.

To remove the computer’s power supply, you could require to undo four or five screws.

On the website of the seller, look up PC specifications

You may go to the official webpage and look for the pc product code you use in the situation where you have a custom build computer from any vendor.

On the manufacturer’s website for your pc version, you may find the PSU used in that model.

Determining the power usage of your power supply could be done much more quickly and easily with this approach. Additionally, it is very handy because most pre-configured computers do not have labels on their power supply.

Therefore, search up the model of your pc on Internet, and you may get the power rating in the first results pages.

Look at the box of the power supply for information

You may verify the brand and specifications on the pass-apply carton if you have one. Several of the power supplies have a global handbook. To learn more about it and how to set up the power supply on your pc, read the documentation.

Examining your computer’s power supply

You should have a screwdriver before starting. The middle size should function. Also, you need to find a dry surface, leveled, and free of debris.

Shut off your computer completely. You can press “Start,” “Power,” and “Shut Down” in that order. Disconnect it after turning it off.

The side plate, which is a piece of the casing, should be removed with care. Based on the type and size, some cases may be unlatched, while others need you to fetch the screwdriver and unscrew anywhere from two to eight screws. Find the electricity source. It will be close to the port where you earlier disconnected the device’s power cable.

When the power supply has been located, you may check it to get any critical information, such as the maximum output, shown in watts, and its efficiency rating.

At the very least, attempt to identify the model name of the power supply so that you may perform a Quick google using it if you have a hard time finding the specific data, you’re looking for.

Checking cables and specifications

When you have access to your power source within your casing, you may read the branding to learn more about it. Several PSUs include a sticker tag on one side that has essential data about the PSU from the vendor. It displays the wattage output and information about the power supply, such as the voltage rails’ power and current specifications.

The three types of power supplies are non-modular, semi-modular, and modular. All of the cables are already linked in non-modular power supplies, but only two are present in semi-modular PSUs—the 24-pin ATX and 4/8-pin EPS power cables. There are no pre-connected cables in modular PSUs.

ATX, EPS, and SATA cables are shared by all contemporary power supply units. Most of the contemporary PSUs also have PCI-E cables for powering graphics cards, and larger wattage PSUs include many cables of this type to meet demanding power needs.

Power Supply Size

Your issues cannot be solved by simply knowing the wattage and licenses of the power supply. It would be important if you took into account its dimension as well since your PSU may not slide appropriately within the chassis of your computer. For individual computers, there are primarily 3 PSU sizes known. As follows:

  • power supply for ATX and ATX12v
  • power supply SFX-L
  • SFX energy source

The Fully Modular ATX power supply has the finest power supply dimensions. Most powerful gaming computers require a power supply of this magnitude.

The ATX power supply usually has dimensions of 150mm x 86mm x 140mm, which is large enough for rapid cooling. Similar in size to ATX power supplies is the ATX12V model.

Several pre-built PCs use the SFX12V or SFX-L PSUs. Additionally, tiny form factor computers, such as mini ITX PC designs, primarily employ SFX power supply and EPS12V supplies.

Having a power supply that is large enough and fits within the computer casing would be beneficial. An ATX PSU should work fine if you have a mid- or full-tower computer chassis.

Before an update is the most crucial moment to inspect your power supply. To operate effectively, new hardware models (or just a same-gen amelioration) usually need a significant amount of more power. For example, upgrading from a 2080Ti to a 3080Ti will logically demand between 50 and 100 more watts of electricity. This is usually the case when upgrading gear, so it is critical to know how much power you have to work with.

Differentiating Custom from Standard PSUs

In principle, power supplies may be split into two groups: Custom and Standard. Standard power supplies include PSUs built by Cooler Master, Corsair, EVGA, Antec, and Thermaltake, set up mostly for gaming computers. These PSUs employ high-quality cables with sleeves and are substantial.

Most of these PSUs have an outside coated in black and several wires, notably PCI-E cables for graphics processors. However, unlike prebuilt computers from Dell or HP, custom power supplies are lightweight and mostly have bodies made of polished metal.

Their fans, in contrast to the trademarked power supplies, are on the back side rather than the top or bottom. This is because they can employ less expensive components and have better cooling than trademark PSUs.

These power supplies are mainly without casings and have fewer wires; difficult to find PCI-E power connectors for graphics cards


Even while these techniques are effective, some people will undoubtedly not benefit from them. It’s possible that your Computer is second-hand and no one knows what power supply it uses. Maybe you constructed it a very long time ago and are just unable to recall where the invoice is. You’ll need to unlock it in this situation, although it’s often not a difficult process.

To verify if you can read the information on your PSU sticker from there, all you have to do is pull off the side plate of your Computer. Most of the time, an easy Google search will be enough to complete your search, which isn’t too bad. With any luck, this guide has assisted you in finding a solution to your matter and has given you a better understanding of the relevance of your power supply.
