Power Supply Unit Computer Science

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. It also regulates the voltage to eliminate spikes and surges common in most electrical systems. 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.

The power supply converts a 110 115 or 220 230 volt ac alternating current into a steady low voltage dc direct current usable by the computer and rated by the number of watts it generates.

Power supply unit computer science.

Power supply unit or psu is a hardware that is responsible for converting the consumer supply current to consistent electronic circuit current of computer. The power supply then pulls the required amount of electricity and converts the ac current to dc current. 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. Most modern desktop personal computer power supplies conform to the atx.

It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require. The image shows an antec true 330 a 330 watt. If must have noticed a usual car or motorbike repairing shop some of them have a box like unit with various output terminals they test the bulbs and other electrical and electronic components by attaching with it. The switching power supplies used today are much smaller and lighter.

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. A power supply unit or psu converts mains ac to low voltage regulated dc power for the internal components of a computer. 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.
