Power Supply Unit Computer Science

N also called a power supply unit or psu the component that supplies power to a computer most personal computers can be plugged into standard electrical outlets.

Power supply unit computer science.

The power supply unit is the piece of hardware that converts the power provided from the outlet into usable power for the many parts inside the computer case. The image shows an antec true 330 a 330 watt. Abbreviated as ps or p s a power supply or psu power supply unit is a hardware component of a computer that supplies all other components with power. It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require.

The switching power supplies used today are much smaller and lighter. Power supply unit or psu is a hardware that is responsible for converting the consumer supply current to consistent electronic circuit current of computer. Most modern desktop personal computer power supplies conform to the atx. It also regulates the voltage to eliminate spikes and surges common in most electrical systems.

A power supply unit or 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. They convert the 60 hertz hz or cycles per second current to a much higher frequency meaning more cycles per second this conversion enables a small lightweight transformer in the power supply to do the actual voltage step down from 110 volts or 220 in certain countries to the voltage needed by the particular computer.
