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.
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.
The mother board, power supply, and chassis
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.
The job of a computer power supply is to give power to the computer even when it doesn't have any power. It is normally your adapter that comes with the computer.
To power all the components of a computer.
The past tense of "supply" is "supplied."
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.
Usually only one, this is the main power source to the computer.
If you are asking from where you can obtain a d.c. supply without using a rectifier supplied from an a.c. source, then the answer is that d.c. supplies are directly available from batteries or from d.c. generators.
The base word of supplied is supply.
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.
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.
A computer power supply takes the AC power coming from a wall socket, and then converts it into lower-voltage DC to power all the components inside. Almost every component of a computer will connect directly to the power supply, with the exception of smaller parts such as fans, which can pull power through the motherboard.
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.
The power supply changes the 120v ac 60 hz (in the us and canada) to dc 12v, dc 5v, and dc 3.3 v that the computer components can use. The power supply is rated in power supplied as watts of power.
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
