a)
To convert the AC voltage from the wall outlet into the various DC voltages required by the computer components.b)
To store electrical energy like a battery in case of a power outage.c)
To regulate the speed of the system fans.d)
To protect the computer from viruses.Explanation
The PSU is a critical component that takes high-voltage Alternating Current (AC) and transforms it into the stable, low-voltage Direct Current (DC) that computer parts need to operate. It supplies several different voltages, typically +3.3V, +5V, and +12V.Related questions
