What are the functions of power supply unit?
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
What are the 5 power supply connectors?

What are the three functions of power supply?
Power Supply Functions Provide some method of voltage division to meet equipment needs. Change ac voltage to pulsating dc voltage by either half-wave or full-wave rectification. Filter pulsating dc voltage to a pure dc steady voltage for equipment use. Regulate power supply output in proportion to the applied load.
What is meant by power supply?
Definition of power supply : a device providing power to electronic equipment and sometimes designated A, B, or C according to its function of heating vacuum tube cathodes, causing a flow of electron current in plate circuits, or applying a direct voltage in grid circuits.
What are the main parts of power supply explain with block diagram?
From the block diagram, the basic power supply is constituted by four elements viz a transformer, a rectifier, a filter, and a regulator put together. The output of the dc power supply is used to provide a constant dc voltage across the load.
What connector has 4-pins?
4-pin Fan. The 4-pin Fan power connector is found on motherboards within a computer case. This connector provides power to cooling fans and is typically used on the fan that cools the CPU.
What are the components in a power supply?
In the desktop system, a power supply is a metallic box which contains the transformer, capacitors, wires and diodes etc. and it converts the power in AC (Alternating current) to the power in DC (Direct Current) because the components in the system require only DC current for functioning.
What is the best brand of power supply?
It hails from a reputable brand – Antec, Corsair, Enermax, FSP, OCZ, PC Power and Cooling, Seasonic, Silverstone and XFX are well recognized as the best computer power supply brands. Coolermaster , Rosewill , and Thermaltake produce solid power supplies as well, but it’s best to avoid their low-end models.
What are the functions of power supply?
A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.
What are the different types of power supplies?
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching.
