What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?

A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.
Another answer
The secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.

Alternating current travels in only one direction and is typre of current that most electronic devices require including computers?
True ~tekno
What does the symbol AC stand for?
If you're meaning AC as in Electricity then you're talking about Alternating Current. There are normally symbols on Electronics or Computers.
A power supply receives what type of power?
It depends on the type of power supply. A power supply used in a desktop computer is generally supplied with AC (Alternating Current) and produces several levels of regulated DC (Direct Current) voltages required by the electronic circuits.
Changing alternating current to direct current is called?
Rectification
What is AC power plug?
an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
What is the meaning of voltages?
D.C. stands for direct current. A.C. is alternating current.
Electric current from a generating plant is?
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
What converts direct current to alternating current?
To convert direct current to alternating current you need either an inverter or a motor-generator set.
Which device is used to convert direct current into alternating current?
An inverter
What is use of rectifier?
Rectifier is used to convert alternating current to direct current.
What is the purpose of a alternator?
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
Alternating currents travels in only one direction and is the type of current that most electronic devices require including computers?
Alternating currents travels in only one direction and is the type of current that most electronic devices require including computers?
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
What is an example of a direct current?
A direct current (DC) is the continuous flow of electric current that circulates in one direction and keep the same polarity (positive or negative). Example of direct current are batteries and generators. There are electronic devices, like computers, that work with direct current, but they require of some additions to convert alternating current to direct current.
Why the solar panel power cannot be transfer to the meter?
Solar panels are direct current (DC), the electric in the meter is alternating current (AC). You need a special transformer to convert from direct to alternating. This usually has to be done since everything in your house usually runs on alternating current.
Why alternating current is use for electrical system?
The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
