Technology Explained


PSU: A Power Supply Unit (PSU) is an essential component of any computer system. It is responsible for providing the necessary power to the components of the computer. It converts the alternating current (AC) from the wall outlet into the direct current (DC) that the computer components need. The PSU also regulates the voltage and current to ensure that the components are not damaged by too much or too little power. The PSU is also responsible for providing the necessary cooling to the components, as well as protecting them from power surges. In the computer industry, PSUs are used in desktop computers, laptops, servers, and other electronic devices. They are also used in gaming consoles, home theater systems, and other consumer electronics.
