A power supply on a computer is a component that supplies power to the other components of the computer. It is responsible for converting the alternating current (AC) from the wall outlet into the direct current (DC) that the computer components use. A power supply on a computer typically has a wattage rating, which is the maximum amount of power that it can supply.
When choosing a power supply, it is important to make sure that the wattage rating is high enough to support the components that will be using it. For example, a power supply that is rated at 350 watts will be sufficient to power most desktop computers, but it will not be enough to power a high-end gaming computer.
It is also important to make sure that the power supply is compatible with the motherboard. Some power supplies come with a variety of connectors that can be used to connect to the motherboard, while others require the purchase of a separate connector.
One thing to keep in mind when installing a power supply is that it should always be installed by a qualified technician. Improper installation can result in damage to the computer and can even be dangerous.

What are the 3 types of computer power supply?
There are three types of computer power supplies: ATX, BTX, and ITX.
The ATX power supply is the most common type. It is a rectangular box that plugs into an electrical outlet and the back of the computer. The ATX power supply has a large fan on the back to keep it cool.
The BTX power supply is a newer type of power supply that is more efficient than the ATX power supply. The BTX power supply is a rectangular box that plugs into an electrical outlet and the back of the computer. The BTX power supply has a small fan on the back to keep it cool.
The ITX power supply is the smallest type of power supply. It is a square box that plugs into an electrical outlet and the back of the computer. The ITX power supply does not have a fan and does not cool well.
What does a power supply do?
A power supply, often simply called a PSU, is an electronic device that supplies power to an electronic circuit. A power supply converts mains AC to low-voltage DC, and may provide a wide range of voltages and currents depending on its design.
A power supply is an essential part of any electronic device, and without one, the device would not be able to function. A power supply typically contains an input jack for connecting to the AC power mains, an output jack for connecting to the device’s circuitry, and a switch to turn the power supply on and off.
The input jack on a power supply is usually a 3-prong AC connector, and the output jack is usually a 2-prong DC connector. However, some power supplies have a USB connector in place of the DC connector.
When the power supply is turned on, it converts the AC voltage from the mains to the DC voltage that is needed by the device. The amount of voltage and current that the power supply provides depends on its design.
Most power supplies provide a fixed voltage, which is set by the voltage rating of the power supply’s capacitors. However, some power supplies provide a variable voltage, which can be adjusted by turning a dial or pressing a button.
The current that a power supply provides is typically fixed, but some power supplies provide a variable current, which can be adjusted by turning a dial or pressing a button.
Most power supplies are linear power supplies, which means that the output voltage is a close approximation of the input voltage. However, some power supplies are switching power supplies, which means that the output voltage is not a close approximation of the input voltage.
Switching power supplies are more efficient than linear power supplies, and they generate less heat. However, they are more complex and expensive than linear power supplies.
Most power supplies are designed to be used with a specific type of device. For example, a power supply that is designed to be used with a laptop will not be suitable for use with a desktop computer.
Power supplies are available in a wide range of voltages and currents, so it is important to select the correct power supply for the device that is being powered. If a power supply is not compatible with the device, it may damage the device or cause it to malfunction.
It is important to be aware of the maximum current and voltage that a power supply can provide, as exceeding these limits can damage the power supply or the device that it is powering.
It is also important to be aware of the power rating of the power supply. The power rating is the maximum amount of power that the power supply can provide, and exceeding this limit can damage the power supply or the device that it is powering.
When selecting a power supply, it is important to consider the type of device that it will be powering, the voltage and current that it needs, and the power rating of the power supply.
Does computer have power supply?
A computer system requires a power supply to function. The power supply converts AC power from the wall to the DC power that the computer system needs. The power supply also provides power to the fans in the computer system, which keep the system cool.
Most desktop and tower computers use a standard ATX power supply. This power supply has a number of connectors that plug into the motherboard and other components in the computer system. The power supply also has a number of fans that blow air through the system to keep it cool.
Laptop computers use a variety of power supplies, depending on the model. Some laptop computers use a standard AC adapter, while others use a more specialized power supply.
It is important to ensure that the power supply in your computer system is adequate for the components in your system. If you are using a high-end video card, for example, you may need a power supply with a higher wattage rating.
If you are having problems with your computer system, it may be due to a problem with the power supply. In this case, it is recommended that you replace the power supply with a new one.
How do I check my power supply?
A power supply is an electronic device that supplies 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 found in a wide range of applications.
A power supply is typically a box-like enclosure that houses one or more transformers, switching circuits, and rectifiers. The input voltage is AC, but the output is DC, which is then passed along to the load.
There are a few ways to determine if your power supply is functioning properly. One is to check the output voltage. To do this, you’ll need a multimeter. With the multimeter set to DC volts, connect the probes to the power supply’s output terminals and measure the voltage. It should be within the range specified by the manufacturer.
Another way to test a power supply is to measure the current draw. This can be done with a current meter or an ammeter. To do this, you’ll need to connect the meter in series with the load. With the power supply off, measure the current draw. It should be within the range specified by the manufacturer.
If the power supply is not providing the correct voltage or current, it may need to be replaced.
What are the two main types of power supply?
There are two main types of power supplies: linear and switching.
Linear power supplies are the traditional type of power supply. They take AC input and convert it to DC output using a transformer. This makes them bulky and inefficient, and they can be noisy.
Switching power supplies are more recent and use a switching regulator to convert AC to DC. This makes them much more efficient and smaller than linear power supplies. They are also much quieter.
