Understanding PC Power Supply Definition and Function

What is a power supply Definition exactly?

Understanding Power Supply PC definition as one of the hardware in a computer device that has a role in providing the supply of power. Usually this power supply component can be found on a computer case and is square.

In the power supply definition, basically, it requires an electricity source which is then converted into energy that drives electronic devices. The system works quite simply by changing the power of 120V into the form of flow with power according to the needs of these components.

The power supply definition accordance with the understanding of the power supply on a computer, the main function is to convert AC current into DC current which is then converted into power or energy needed by components on a computer such as a motherboard, Room CD, Hard drive, and other components.

Power Supply Function on the Computer

In Indonesian, Power Supply definition means Catu Daya. The function of the power supply is to provide electrical current power to various components or hardware contained in the computer case.

PC power supply function

The source of electrical energy originating from outside is still in the form of alternating current (AC). When electrical energy enters the power supply, the electricity will be converted into direct current (DC). DC power is then channeled to all components inside the computer case to work.

One the side of the power supply there is a fan that is useful for removing hot air from inside the computer case. In addition, in the power supply there is also a male port type IEC 60320 C14 which functions as a connector between the electrical energy source and the power supply.

Components of Power Supply

Referring to the notion of power supply definition and function, this hardware functions to convert AC current into DC current and distribute it to various computer components inside the chassis. To form a voltage, several components are needed, while the power supply components are as follows:

1. Transformer

This is a component inside the Power Supply that is used to move electricity between two electrical circuits or more through electromagnetic induction.

2. Diodes

This is a combination of two electrode words, namely the anode and cathode. The nature of the diode is to deliver current to the forward voltage and inhibit the current at the reverse voltage flow.

3. Capacitors

Capacitor serves as a complement to the delivery of AC voltage to DC voltage.

4. Resistor

Resistor is a device that helps the Power Supply to reduce voltage, divide the voltage, and limit the incoming electric current, so it will be able to control the hardware on the motherboard.

5. Regulatory ICs

IC Regulator serves to regulate the voltage in the electronic circuit always remains stable.

6. LED

Power Supply LEDs are semiconductor diode-like components that have special features

Power supply definition can be classified into two types, namely:

a. Internal Power Supply

This type of power supply is made integrated with the motherboard or main circuit board. Example; skill, television, DVD Player; the power supply is integrated with the motherboard in the case of the device.

b. External Power Supply

This type of power supply is made separately from the motherboard of an electronic device. For example a Laptop charger and an HP charger.

Types of Power Supply

Based on its function, there are two types of power supply definition that are commonly used on computers and both have significant differences.

The types of power supply are as follows:

a. AT Power Supply

You could say this is the type of power supply that was first used on types of computers in the past such as the types of Pentium II and Pentium III in the year ’97. So that for now the use of AT Power Supply has not been found in the latest types of computer equipment.

This type of power supply definition has some characteristics:

Has 8-12 output terminals connected to the computer motherboard

Generally it has power below 250 watts

Because the power button On and Off is connected to the computer case, then it must be done manually when shutting down the computer.

b. ATX Power Supply

ATX Power Supply is an update of AT Power Supply types. This power supply definition has a more complex design with a more efficient source of electrical energy supply.

ATX Power Supply now is found on the latest generation of computers where the operation can be controlled with software that is installed on the computer. So that it can be set in several modes such as sleep mode, standby mode and mode when the computer is turned off.

Characteristics of ATX Power Supply:

Has 20 to 24 output terminals connected to the motherboard

Use more power

When the PC is shut down, the power supply will completely shut down automatically

How Power Supply Works

According to Power Supply definition and function, when the user turns on the power on the computer, the power supply will carry out checks and tests before running the computer system.

If the test goes well, the power supply will send a signal (power good) to the mainboard as a sign that the computer system is ready to operate.

Furthermore, according to the power supply definition and its function, power supply will divide the power according to the capacity required by each computer component.

In addition to delivering electrical power to computer components, the power supply also maintains the stability of electric current in various components.From the explanation of power supply pc definition and its functions above, this component is as important as the CPU on a computer that is often considered a computer brain.

If there is interference with the power supply, it will cause interference with the flow of power on computer components.
