The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts.

The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
A faulty power supply does not supply any power at all to a computer or supplies incorrect voltages. Most of the time faulty power supplies are not serviceable and require replacement.
A PC power supply typically provides several DC voltages, primarily +3.3V, +5V, and +12V. These voltages are used to power various components within the computer, such as the motherboard, storage devices, and peripherals. Additionally, some power supplies may also provide -12V and +5V standby power for specific functions, like powering the motherboard when the system is off.
The electricity supply system is divided into the transmission system and the distributionsystem. The distribution system is the part of the system which supplies the consumer -in the UK, we are talking about voltages of 33 kV, 11 kV, and 400/230 V.
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
Power Supply
All electricity supplies are a.c. D.C. is used, on occasions, for long-distance transmission (or undersea transmission) at very high voltages, but never for power supplies to homes or businesses.

The two voltage readings on a power supply typically refer to the output voltages it provides, which are often 5V and 12V for standard ATX power supplies used in computers. The 5V output is commonly used for peripherals and logic circuits, while the 12V output powers components like the CPU and graphics card. Some power supplies may also feature additional voltages, such as 3.3V, depending on the application.
