Detailed explanation-1: -A power supply unit (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.
Detailed explanation-2: -An uninterruptible power supply (UPS) device is recommended as it keeps your computer powered on during a power outage or brownout.
Detailed explanation-3: -Your computer’s power supply both converts the alternating current (AC) from an American wall socket to the DC necessary for the internal power needs of the computer, and regulates the voltage. Internally, personal computers utilize +/-12, 5, 3.3, or 2.8 volts DC.
