A computer power supply, or power supply unit (PSU), is an electronic device that provides power to a computer. A power supply unit can be a stand-alone device or it can be an integrated component of a computer case.
A power supply unit converts AC power from the wall outlet into DC power that a computer can use. The power supply unit also regulates the voltage to the correct level for the computer.
A typical power supply unit has a wattage rating. The wattage rating is the maximum amount of power the power supply can provide. A power supply unit should be chosen with a wattage rating that is equal to or greater than the computer’s maximum power requirement.
The power supply unit is an important component of a computer and it should be chosen carefully. A power supply unit that is inadequate or that fails can cause the computer to shutdown or to experience other problems.

What is power supply in a computer means?
A computer power supply is the component that supplies power to the other components of the computer. It converts alternating current (AC) from the wall outlet into direct current (DC) that the computer can use.
The power supply has a number of connectors that plug into the back of the computer to provide power to the motherboard, video card, hard drive, optical drive, and other components. It also has a fan that cools the components inside the computer.
The power supply is an important part of the computer and should be kept in good condition. If it fails, the computer may not be able to start up or may not operate properly.
What is power supply simple definition?
A power supply is an electronic device that supplies electric power to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes called energy converters.
A power supply may be a stand-alone device or an integral part of a larger electrical system. In the latter case, the power supply may be called an AC adapter, a DC adapter, a power brick, or a wall wart.
A power supply typically has an input voltage and an output voltage. The input voltage is the voltage of the electrical source that the power supply uses to generate the output voltage. The output voltage is the voltage that the power supply delivers to the electrical load.
Most power supplies are designed to convert AC power to DC power. However, some power supplies are designed to convert DC power to AC power.
Power supplies are classified by their output voltages. A power supply that delivers a voltage of 5 volts is called a 5-volt power supply. A power supply that delivers a voltage of 12 volts is called a 12-volt power supply. A power supply that delivers a voltage of 24 volts is called a 24-volt power supply.
The output power of a power supply is the product of the output voltage and the output current. For example, a 5-volt power supply that delivers a current of 2 amps has an output power of 10 watts.
Power supplies are also classified by their form factors. A power supply that has the same dimensions as a standard AC plug is called a plug-in power supply. A power supply that has a wider form factor is called a desktop power supply. A power supply that has a narrower form factor is called a laptop power supply.
The output power of a power supply is also limited by its form factor. A desktop power supply that delivers a voltage of 24 volts and a current of 2 amps has an output power of 48 watts. A laptop power supply that delivers a voltage of 24 volts and a current of 1 amp has an output power of 24 watts.
What is power supply and its purpose?
In order to understand what a power supply is and its purpose, it is first important to understand what electricity is. Electricity is the flow of electrons through a conductor, such as a wire. It is a basic form of energy that is used to power just about everything in the world. Devices that use electricity to function need a power supply in order to convert the electricity into a form that the device can use.
A power supply is a device that takes the AC voltage from a wall outlet and converts it into DC voltage that a device can use. It is important to have a good power supply in order to ensure that your device is getting the correct voltage and amperage. A power supply can also provide a clean and stable source of power to help protect your device from damage.
There are a variety of different types of power supplies available, including linear power supplies, switching power supplies, and portable power supplies. linear power supplies are the most common type and are usually used in desktop computers. A switching power supply is more efficient and can be used in smaller devices, such as laptops and cell phones. Portable power supplies are a great option for people who need to take their power with them on the go.
No matter what type of power supply you choose, it is important to make sure that it is compatible with your device. You also need to make sure that the power supply can handle the wattage of your device. If you are not sure which power supply to choose, consult the device’s manual or the manufacturer’s website.
Where is power supply in computer?
A power supply is an electronic device that supplies power to an electronic circuit. The power supply accepts an input voltage, converts it to the proper voltage and current levels, and provides the power to the circuit. A power supply is a necessary component of all electronic equipment.
Computers use a variety of power supplies, depending on the type of computer and the type of power connector. Desktop computers use a standard power supply that plugs into the wall outlet. Laptop computers use a power supply that plugs into the laptop’s power connector. Some laptop computers also include a standard power supply that can be used with an adapter.
Most computers use a switching power supply. A switching power supply converts the input voltage to a stepped-down voltage, which is then switched on and off at a high frequency to create the desired output voltage. This design is more efficient than the linear power supply, which uses a transformer to convert the input voltage to a lower voltage.
The power supply is an important part of the computer’s design and should not be overlooked. A faulty or inadequate power supply can cause problems with the computer’s operation.
What are the 3 types of computer power supply?
Power supplies are an essential part of computing, and come in a variety of shapes and sizes. There are three main types of computer power supply: ATX, SFX, and TFX.
The ATX power supply is the most common type, and is found in most desktop computers. It is a large, rectangular unit that plugs into the wall and the back of the computer. The ATX power supply supplies power to the motherboard and other components in the computer.
The SFX power supply is a smaller, square unit that is designed for small form factor computers. It is about half the size of the ATX power supply and plugs into the wall and the computer in a similar way. The SFX power supply supplies power to the motherboard and other components in the computer.
The TFX power supply is the smallest type of power supply, and is designed for small form factor computers. It is about the size of a deck of cards and plugs into the wall and the computer in a similar way. The TFX power supply supplies power to the motherboard and other components in the computer.
All three types of power supplies are available in both voltages (110V and 220V) and wattages (ranging from 300W to 1000W).
Which type of power supply you need depends on the type of computer you have. If you have a desktop computer, you will need an ATX power supply. If you have a small form factor computer, you will need an SFX or TFX power supply.
If you are not sure which type of power supply you need, consult the documentation that came with your computer or the manufacturer’s website.
