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

The power supply in a PC is a complex device using switch mode circuitry and Transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
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.
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.

...It "supplies the power" to whatever device you're referring to.Baffling, I know.Another answer:A power supply converts 120V or 240V AC power (sometimes called "wall", "line" or "mains" power) into various regulated DC voltages needed in a piece of electronic equipment. In a computer, for example, the power supply will typically provide +12V, +5V, +3.3V and -12V sources to the various components. Voltage regulators in the power supply help keep the voltages steady, even when the input voltage sags.
