Definition of Computer Power Supply, Function, How It Works, Complete Type – In this discussion we will explain about Computer Power Supply. Which includes the meaning, function, working method and types of power supply which will be explained in full and easy to understand. For more details, please see the review below carefully.
Definition of Power Supply, Function, How it Works and Types of Connectors
Let's review in full about this one hardware.
Definition of Computer Power Supply (PSU)
Power Supply is a piece of hardware (hardware) that functions to supply power or electrical voltage directly to the components inside the computer casing. The power supply supplies to the motherboard, hard drive, heating, DVD drive and other devices in the computer case.
Power supply is now a lot that produces it. Various brands with different qualities are also an option for consumers to prefer a quality power supply and of course guaranteed. Some power supplies are deliberately made for high-specification computers, so that users are safe from low voltages, such as on gaming-specific computers. So the power supply already uses a power supply with a total Watt output of more than 450 Watt, the minimum used is 600W.
Power Supply Function
The function of the power supply is to convert AC current to DC. So flowing current from electricity to computer hardware with DC current operation is in the form of alternating current input.
How Power Supplies Work
The way the power supply works is when you press the power button on the computer, the power supply will check and test before letting the system start or start. If the test is successful, the power supply sends a special signal to the mainboard/motherboard, which is called power good.
Power Supply Types
The type of power supply on a computer is now divided into two types. Namely AT power supply and ATX power supply. Here's the full explanation
-
AT Power Supply
AT power supply is a type of power supply that can be said to have been around for a long time. In its heyday, this type of power supply was often used by computers with Pentium II and Pentium III. Even though it's rarely found now, the AT power supply actually has its advantages.
This type of power supply has a power cable connected to the motherboard which is divided into two, namely the P8 and P9 connectors. The risk of incorrectly installed by using this AT power supply is very small, considering that installing it requires high precision. The usual error is upside down considering that there are two connecting connectors. For correct installation, you must pay attention to the black power cable on each connector. Pair it right in the middle of the connection to avoid a short circuit. To turn off the AT power supply, you have to press the power button directly because this type is directly connected to the computer case.
-
ATX Power Supply
This type of power supply has a simpler appearance than the previous power supply. For this type of power supply, the connector cable and the motherboard have become one with a total of 20 PINs. Therefore, this power supply is also called the ATX 20 PIN Power Supply.
To install it is very easy to do. The thing that needs to be done when installing it is to make sure to install it correctly because if it's wrong it can cause damage to the port or connector.
The advantage with the ATX power supply rather than the AT is the power button. If you use an ATX 20 PIN power supply, it is equipped with an auto shutdown function, which turns off the power supply when the computer is turned off. So we don't need to press the power button like the AT power supply. Of the types of power supplies mentioned above, ATX power supplies are currently more widely used and used on every computer.
Types of Power Supply Connectors
In the power supply there is a connector whose function is to connect the voltage from the power supply to the motherboard and other devices. Here are the types of connectors in the power supply
- Motherboard 20/24 PIN ATX connector
- 4 pin peripheral power connector (for devices such as DVD Room, hard drives, fans)
- 4/8 pin 12V connector (for server motherboards)
- PCIe 6 pin connector (for VGA card/PCIe graphics card)
- Floppy Connector (for floppy disk drives)
- SATA connector (for hard drives/optical drives of the SATA type)
Thus has been explained about Definition of Power Supply, Function, How it Works and Types of Connectors hopefully can add to your insight and knowledge. Thank you for visiting.
