What is a PC power supply? - How it works, types and characteristics
This tool fulfills the function of supply electricity to the computer , called a transformer, because it is responsible for converting energy into direct current. Because this type of electricity is what the computer and its components need due to the low voltage, since they range from 9 to 12 volts.
This unit is known as a power supply and this is very important, it also gives electricity to the motherboard and each of its components. Some are: optical drives, video cards , USB devices among others, this is responsible for the proper functioning of the computer.
This power source is vitally important to the computer components, knowing that without this part the rest of the hardware would not work . We also call the power source the power supply.
Find out how the PC power supply works
It should be noted that the power supplies are rated in watts in because of the power they provide to the computer. Not to mention that each part of the computer needs moderate amounts of energy. For this reason, it is very important that you have the correct power supply that will provide the right amount of power to your computer.
Currently, the rail load is at 12V, leaving the other rails almost obsolete. Emphasizing that the power supplies will always be defined in watts; at the same time, it is important to note that the computer is turned on and off via a button, although it can also be turned off via the menu.
Day after day, the advancement of technology globally is impressive. Previously, power supplies were heavy and voluminous , this is to convert the line voltage to the appropriate voltage for the computer.
It should be noted that the energy sources that exist currently are light and small because they transform the 60 Hz current into higher frequencies. Thus making it possible to reduce the voltage to the most suitable for the PC. Remember that it is essential to clean your PC's power supply.
Power sources can be classified into two groups
Source types are used to control the energy and voltage that equipment needs to operate. They are classified into:
To the power source
This device is capable of transforming alternating current into direct current necessary for the electrical elements of the equipment, it is located in a computer cabinet.
This type of source has several characteristics, it has a mechanical switch that is used to turn the equipment on and off, saves electricity, you can turn off the power, they can be incorporated into old and modern equipment.
Some of the parts of a power source HV are: a mechanical switch, a power connector, a fan, an HV connector, a voltage selector and the power connector to other elements.
ATX power supply
ATX power source is called source digital or push button , it has the same objective as AT. It is responsible for transforming alternating current into direct current, thus controlling the energy that the computer needs to function.
Some of the most outstanding features it has, ignition is digital, source shutdown is software controlled, it can be installed in old and modern microprocessors, it controls electric power.
The ATX power supply consists of several parties which are: the power connector, the fan, the ATX connector, the voltage selector, the SATA connector, the BERB and MOLEX 4-terminal connector.
At the same time, it is important to note that there are power sources depending on their quality, and they are divided into: original power sources, imitation power sources and sources of power. certified energy. You just need to consider evaluating all of your computer's indications and correctly selecting the best power supply your PC needs.
