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.
What performs a check on all the internal components?
Power on self test
Will a psu only deliver what is needed?
Yes, the power supply will obviously only draw the power required for what ever load you place on the unit from your internal computer components. Each power supply has effeciency ratings some power will be lost.
What is the function of a PSU?
The PSU's main job is to break down the amount of electricity and distribute it to different parts of the board. The parts are to delicate to handle the huge amounts of electricity that comes directly from the socket on the wall. Aswell as this, the electric comming from the wall is AC and the PSU converts this to DC. And importantly it helps with spikes and brown outs in the supply from the wall.
What are some computer components that are supplied power directly by the power supply?
Hard drives, floppy drives, case fans, motherboard

What is computer shutdown?
a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.
How does a computer tower work?
The computer tower is a large case that contains all of the circuit boards, drives, and internal power connections of the computer. The case provides convenience, protection, and the ability to cool all of the electronic components simultaneously.
What does the internal battery inside a cell phone do?
Seriously ?... It provides power for the phone's electronic components to work !
Dual power supply?
A dual power supply refers to a system that provides two separate power sources to a device or circuit. This setup offers redundancy and can help improve reliability in case one power source fails. It is commonly used in critical systems where uninterrupted power supply is necessary.
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 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
How does a psu work in a computer?
The power supply in the computer is what provides power to all of the components inside the PC. It also has the role of powering up the computer. The power supply not only powers the motherboard, but everything else inside the computer, including the video card, peripheral cards, hard drives, etc.
What does power supply does?
A power supply unit (PSU) provides power to all the components in the computer. Typically that would include the system board, the processor, the video cards, and storage devices.
What is the purpose of the power supply?
To power all the components of a computer.
What performs a check on all the internal components?
Power on self test
