Sometimes when people buy a computer power supply unit (PSU), there are several components in the box:
a AC power cable to connect the power supply to the wall mains outlet,
the power supply itself (PSU) that converts mains power into more useful forms of power,
and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer.
(On a modular power supply unit, those cables can be detached from the PSU).
A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component.
Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.

What is the purpose of the power supply?
To power all the components of a computer.
How do components get power?
A computer's power supply unit provides all needed voltages for the components of a computer that are internal. Externals either draw power from the USB bus (which in turn gets it's power from the aforementioned PSU or a Hub with a power supply) OR have their own internal power supply with a cable.
State two reasons why computer needs to be connected to a stable power supply?
A stable power supply is crucial for a computer for several reasons: 1. Prevention of Data Loss: Sudden power outages or fluctuations can lead to data loss or corruption. A stable power supply helps prevent these issues by ensuring that the computer's components receive consistent power, reducing the risk of data loss. 2. Protection of Hardware: Fluctuations in power supply can damage the computer's hardware components, such as the motherboard, hard drive, and processor. A stable power supply helps protect these components from damage, prolonging the lifespan of the computer.
What is the function of power supply in system unit?
The function of the power supply is to convert wall current to the correct current for the computer and distribute power to all the internal computer components.
What provides power to the internal components of the computer?
In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.
What a computer power supply does?
a computer power supply (PSU) provides poer to all the components in the system and makes sure they they do not too much power to overload them or not enough to cause them to shut off

What is the function of the power supply in a computer?
It is to allow your computer to run without having to keep it charging right next to a socket all dayThe main purpose of a power supply is to distribute the right amount of power to all the components of a computer.
What is fuction of power supply?
The power supply makes the computer run, without any type of power supply it would be impossible to run a computer. The mains power supply for a laptop and the power supply unit of a desk top, both convert the high AC voltage from the mains power and convert it to low voltage DC, for the electronics of a computer to use.
What is PC mani supply?
A PC Main Supply is what gives the computer power to operate, in desktop computers they have to constantly be connected to some type of power outlet. Diagram. Plug socket > Cable > PSU (power supply unit) > Motherboard > power to all components in the computer.
What is a power supply?
A power supply gives electrical power to all the components and parts of the computer. The power supply consists on several wires that connect to specific parts of the computer. Examples are the IDE/SATA CD/DVD Drive, IDE/SATA Hard Disk Drive, the motherboard, etc. Power supplies are only a computer part in a desktop computer, NOT a laptop computer.
What components define the system's form factor?
The mother board, power supply, and chassis
