what is power supply in computer
Power Supply
The power supply is located at the back of the computer, where the power cord is connected. It transforms the 240 Volt AC main power supply into the various DC voltages required by the machine. You will notice a number of power cables coming out of the power supply and going to various parts of the computer.
The power supply is the ultimate energy supplier to the computer, so it runs as long as the machine is on. To prevent overheat damage each power supply includes a fan that circulates air through the case.
Be careful to open the computer case. You must unplug the computer first and before touching the inside you should touch a grounded metal object to discharge any static charge.
