What is computer power?

Power, or in other words, the power source, is the most important part of any computer system, which is used in all computers from laptops to desktop computers. Power supplies the required power of a computer and without it the computer has no use. Choosing the right power for the computer is very important. If you buy a power supply that does not have the ability to provide the power your computer needs, your system will not work well.For this reason, you need to be familiar with the types of power so that you can choose the best possible power for your computer.

What is the function of computer power?

One of the main questions about power is what is the task of computer power? The power supply or computer power is responsible for converting city alternating current to the current required by the computer. Computer components work with direct current (DC). Power takes city current (AC) and converts it to current (DC). Also, this component divides current between computer components. Each piece requires a different current. This flow is supplied by power.

How does the power supply work?

As mentioned, the power supply divides the current between different parts. Computer parts normally work with 12 to 13 volts. Power receives the 110-230 volt city electricity and converts it to the required current of the parts and delivers it to them. This current is transferred to the computer parts in two ways.Some parts like hard directly receive this current from the power and some parts They also indirectly receive the current from the motherboard.

What are the types of computer power?

The power computer of this part has different types in terms of form factor, the amount of current it supplies and how it works. There are different motherboards in the market; The power supply you choose for your computer must be compatible with the architecture of your motherboard. Also, the amount of current required for different parts is different. Your computer’s power supply must be able to supply the current you need. In the following, we will get acquainted with the types of power based on the form factor.

atx

The most famous and widely used type of power supply is ATX power supplies. These types of power supplies are specially designed for ATX motherboards made by Intel. These power supplies have removed the limitations of AT motherboards made by IBM. Atx power supplies have different types, which include:
• Flex atx: this type of atx power supply has dimensions of about 229 x 191 mm.
• Micro atx: these power supplies are designed and produced with a size of 224 mm x 1244 mm.
• Mini atx: this type of power supply has dimensions equal to 150 x 150 mm.

at

These types of power supplies are compatible with AT motherboards made by IBM. The size of at power is equal to 350 x 305 mm.

lpx

lpx power is another type of power that has different sizes. These power supplies are specially designed for motherboards built with lpx architecture. This type of power meters are equal to 330 x 229 mm.

nlx

Some motherboards have nlx architecture. Power supplies known as nlx have been made for these motherboards. The dimensions of nlx power supplies are 254 x 228 mm.

sfx

sfx power supplies are designed for motherboards that use the architecture with the same name. sfx power supplies have dimensions equal to 125 x 63.5 mm. sfx power supplies are among the smallest power supplies available in the market, which are used for small computer systems with few parts and equipment. This type of power has the ability to supply 90 watts.

What is the difference between power computer and laptop?

Computer and laptop power have a fundamental difference. Computers have bigger and more powerful power because they need direct current and this current is supplied from city electricity. But laptops get their electricity from the battery installed for them. Also, laptops need less electricity than computers.For this reason, their power is smaller and weaker than computer power. The power of laptops is located outside the device and in the way of their charger.

What are the components of the power supply?

Computer power has four important parts. These four parts are: transformer, rectifier, filter and regulator. Each of these parts has specific tasks in Power. The transformer is responsible for increasing or decreasing the voltage. In fact, this piece of work changes the input voltage from city electricity to the voltage required by the computer.The function of an inverter is to change AC current to DC current. The current used in the computer is DC, and an inverter must convert the incoming AC current from the city power to DC current.
The power filter works to eliminate power fluctuations. Because power fluctuations can damage the electrical components in the computer.The regulator ensures the stability of the output current from the power. The regulator is used to keep the voltage level at a certain level and prevents the voltage drop in the system. Voltage drop can cause computer parts to burn and the regulator is designed to prevent this from happening. Power is the first part of the computer that receives the electric current and they are designed to prevent the power fluctuations from reaching the computer parts. Even if these fluctuations are excessive, It causes the power to burn, but the oscillation does not reach the parts and prevents them from burning.

Conclusion

In this article, we have fully answered the question of what is computer power. Power computer has different types, each of which is made to connect to different motherboards with different designs. Power is one of the vital parts of the computer, which is responsible for providing the electrical energy needed by the computer. Without power, the computer practically cannot work. This part takes the current of city electricity and converts it into the current required by the computer parts. This flow is different for each piece; Depending on the type of work, each part receives the required current directly or indirectly from the power supply. To buy power, you should pay attention to its dimensions and architecture. If the power supply you buy does not have the ability to supply the required current of your computer components or is not compatible with the architecture of your motherboard, it will not be useful.

FAQ

What is the use of computer power?

Computer power is generally made to supply the electricity required for computer operation. Computer parts can only work with DC current. This part takes the alternating current (AC) of city electricity and converts it to direct current (DC). It is also responsible for distributing the flow between computer parts.In general, computer parts need a current equal to 12-13 volts to work. The power receives the 110-230 V urban current and converts it to the 12 V current required by the computer. Some parts, such as the hard drive, directly receive this current from the power supply. Some parts also receive this current indirectly through the motherboard. The most important thing when choosing a power supply is that the power supply has the ability to supply the required current for your computer.
What are the types of computer power?

Power computers have different dimensions with different structures, each of which is used for different types of motherboards. These models are: atx, at, lpx, nlx and sfx. ATX power supplies are designed for ATX motherboards made by Intel. AT power supplies are compatible with AT motherboards made by IBM. lpx power supplies are another type of power supplies that have dimensions equal to 330 x 229 mm. nlx power supplies are suitable for motherboards that have nlx architecture. sfx power supplies are among the smallest available in the market, which are designed for small computer systems.
