Best Answer

Your power supply unit, PSU. Takes AC power and distributes so much power to each

connector. Each PSU, depending on the wattage of the unit gives each connector

so much voltage. Each connector is designed for a certain piece of hardware that requires

different voltage.

What supplies power to a computer?

The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.


What regulates the wall voltage to the voltages required by the computer chips?

The Power Supply


How the power supply works in the computer?

The power supply in a computer runs the 110 volts mains power through a transformer into a lower voltage, then lowers that into different voltages (+5v, -12v, +12v, +3.3v) which i believe are then stabilised independently. The power supply also handles the turning on/off the voltages triggered by a signal from the motherboard.


Should your computer have -5 volts?

Yes, -5 is one of the voltages a power supply puts out.


What are the voltages values that are produced by the power supply?

Depends on the power supply, usually theres a red switch on the back that says the voltages that I can be. You can also change them by going to the boot setting(setting when the computer boots up)


The power-good signal from the power supply prevents the computer from?

The power supply's power-good signal prevents a computer from operating on improper voltages and potentially getting damaged. Typically, a computer will only start up after receiving the power-good signal.


What inside the system unit regulates the wall voltage to the voltages required by the computer chips?

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.

Does a computer's power supply generate electricity?

In short, no. The power supply takes the alternating mains voltage and reduces it to the low voltages and direct current needed by the components of your PC.


What does the power supply unit do?

It takes the mains supply and converts it to various lower voltages, suitable for the electronics in the computer. Usually 5v 12v 3v
