The power supply unit, also known as the power supply, is responsible for powering the motherboard and the entire device. In addition, you do not have a program that displays power supply information on your unit’s screen. Here are some ways to find out what type of energy source you have.
Power supply to know
To be precise, the PSU, along with the motherboard, is the only component that is directly connected to almost every other hardware device in the machine. Because of the special position of nutrition, it is very important that you know it well. The power supply should also have a built-in surge protector to ensure the safety of other components in your PC.
It is interesting to note that the power supply is at the bottom of the list of most important features for someone building a PC. However, because the power supply plays a crucial role, it is an essential part of your system’s hardware. In other words: In the long run, the choice is as important as your graphics card or motherboard.
Also note that the choice of hardware quality can be the deciding factor between a well-configured device and one that often looks bad. If you don’t know where the power supply is when you build your PC, you may experience frequent crashes and startup problems. The power supply is often the unsung hero when your PC is running.
Without a perfect power supply, your computer would not work. It’s worth noting that choosing a power supply for your system usually depends on how you use your PC. For example, a gaming PC needs more power than a regular PC. In addition, monitors or even high-end computer peripherals, such as the mouse and keyboard, require much more power.
Therefore, it is important that you find the right power supply for your individual needs. And in case you didn’t know: Total power is the determining factor of how much power your system needs to operate. Choosing an oversized power supply is one of the most important steps you can take to ensure the future of your unit.
In other words: If you plan to upgrade your PC at a later date, the power supply can be more easily adapted to your pulsed power needs. When buying a power supply, it is also important to know the power requirements of each component. If you have a normal PC, you don’t need to worry. However, if you want to perform special tasks with your PC, you need a powerful power supply.
Ways to know the type of power supply installed in your PC
You need to know how to determine the type of power supply for your system. Also make sure that all power supplies in the PC are labeled with their power rating. Here are some ways to find out what type of power supply is installed in your unit.
Physical method – opening the CPU housing
This is one of the preferred methods of finding out what type of power supply is installed in your PC. Look for a sticker or label on the side panel with important information about the power supply. The type of information usually includes the name of the power supply, the model number, the power and capacity, and the voltage.
In case you didn’t know, this sticker is in every power supply. It is present on the sides or on the top. The location of the sticker depends on the manufacturer. However, opening the panel and finding the sticker will not help if you are not familiar with the technical information on the sticker.
With these things in mind, let’s take a look at the specifications that are usually on the label.
Power supply name and model
On the label itself you will find the brand and name of the power supply and the model number. You will also find the total power of the power supply, which is usually printed in clear letters. You will also find different levels of certification and an indicator of compliance with quality standards directly on the sticker.
The power is also written in the largest font so that the user can easily identify the power supply. Power gives you important information about the capabilities of the power supply.
The input voltage is usually measured in AC current supplied by the power supply. For most countries in the United States and South America, the input voltage is between 110V and 127V. However, for Europe and Asia, the operating voltage is between 110V and 240V.
Interestingly, the MEPs available in Asia, Europe and the UK are equipped with an automatic switching mechanism for voltage detection and can switch according to the needs of the PC.
On the other hand, some modern power supplies have a physical switch that allows you to select the correct voltage based on your region’s voltage specifications.
Below each voltage value is the maximum amount of current that each rail can supply. If z. B. A 12 V rail has a rated current of 35 A, it cannot supply more than 35 A even if the current demand increases. And when the demand for electricity increases, the power supply is overloaded, causing it to fail.
Always remember that the output of the power supply is direct current. DC output refers to the output voltage provided by the power supply. The standard output voltages provided by the power supply are also called rails. Normally you get 3.3V, 5.5V, 12V and 5VSB from power supplies.
It is common for power supplies to have multiple 12V rails, such as a 12V rail and a square 12V rail. Note that the 5VSB always remains powered, as it powers the BIOS, keyboard, mouse, LAN ports, etc. It also provides a small amount of power to the motherboard and BIOS when the device is turned off and the mains power remains on. It also provides a small amount of power to the motherboard and BIOS when the device is turned off and the AC power supply remains on.
Maximum power refers to the total power you get from one rail or combination of rails. It is interesting to note that the power of the 3.3V and 5V rails is calculated and added together. Instead, the power for the 12 V rail is always specified separately. Again, it is important to note that power is calculated in watts, which is the product of current and voltage.
Under each cell of the voltage table you will find a label for the maximum current load. Note that this particular word is omitted in most cases. However, with most power supplies you will find these directly under the corresponding voltage. Always remember that overloading the maximum load may cause the unit to stop completely.
There are many power supply manufacturers that use a combined 12V power supply rail. This is because the 12V rail drives most of the components, while the other charges all the rails.
More information about CCP can be found on the brand website
This method is useful if you have a PC from one manufacturer. In other words, you are using a device that is not assembled with different hardware components. As you can see, there is no need to open the cabinet and look for the power supply.
And if you’re inexperienced, there’s a good chance you’ll damage the power supply. You can also find a lot of information about the power supply in your PC’s manual. However, finding the specifications on the manufacturer’s website is a good option.
How can I check the power supply if there is no physical sticker on the power supply?
Otherwise, all power supplies should be labeled with the specification. So if you can’t find the physical sticker, the marking may be on the invisible side. If this is the case, the power supply must be removed before it can be identified.
However, only remove the power supply if you are sure it can be removed. However, if you still can’t find the label after removing the power supply, you need to buy a new one. Using an unmarked power supply is dangerous. In many cases, this has resulted in serious damage to users’ equipment.
