Types of Computer Power Supply
The important use of Power Supply is often forgotten by PC users, sometimes users only use the default power supply casing, even though the average default power supply casing does not have pure power, good components and etc which are not good for PCs. That’s why choosing the right types of computer power supply is important.
Power supply is a hardware task to channel electricity directly to computer hardware that requires electrical voltage such as a motherboard, hard drive, dvd room, etc.
Why this component needs to be underlined in the use of PC is because there are many types of computer power supply.
The function of the power supply is to convert alternating electric current (AC) from electricity company into direct current (DC) and then it is channeled to components that need electricity supply.
Another function possessed by the power supply is as a stabilizer or stabilizer of electric current.
As we mentioned earlier, the work of Power Supply is to convert large electricity to small electricity which is later received by VRM in the component.
If the electricity that is changed is bad, then the electricity flowed will become unstable.
Choosing the bad types of computer power supply can cause an “overvoltage” symptom, “over current”, contains a lot of noise until the most dangerous sparks come out such as burning, smoke coming out etc. which can endangers us.
The damage does not only occur on us but bad types of computer power supply is also ultimately will have an impact on the components such as following because the VRM of each PC component has different strengths and not all have extra protection.
For example is for the Hard drive. The VRM on this hard drive is mini-sized, generally not resistant to bad power supply, resulting in a damaged hard drive motor performance, bad sectors etc. the worst is the hard disk is broken.
There are many users who have been affected by the problem of bad types of computer power supply. As the result Hard drive suddenly dies and important data is lost. This kind of accident is absolutely must be avoided by them who save important files.
The other component affected by the bad types of computer power supply is the graphic card. Many people have tried using a “cheap” Power Supply with a power rating of only 450W for high-end graphics cards. Even though the high-end graphics card has become more economical, the user doesn’t care about power supply.
To maintain the performance of your computer for long period, we have to understand types of computer power supply. There are 4 types of functions, related to the stability of the electric current on the computer, namely Over Voltage Protection / OVP that has the function of protecting the PSU from excessive voltage.
This Over Current Protection / OCP in many types of computer power supply has the function of preventing damage due to the entry of high electric current with other component with specific functions such as Over Temperature Protection / OTP and Short Circuit Protection / SSP. The PSU also has an important role to play in controlling the size of the voltage entering the computer.
Unfortunately, there are still a few users who know how vital this PSU is. As a result, the average age of personal computers (PCs / PCs) are relatively short or short simply because they chose the wrong PSU or do not know the right types of computer power supply.
Judging from the understanding and convenience, it is not wrong if this device is called the heart of the computer. So do not choose the wrong types of computer power supply especially if you are PC builders.
What is Types of Computer Power Supply?
A. AT Computer Power Supply
AT stands for Advanced Technology. This types of computer power supply is classified as an old school type and is hardly or rarely used today. Having a 12 pin connector is called an AT power connector. PSU AT is used on Pentium I, Pentium MMX, Pentium II and Pentium III computers.
Characteristics of PSU AT:
The power cable for the motherboard consists of 8 – 12 pins.
The ON / OFF button is manual.The average power is below 250 watts.
When shutdown, the PC does not automatically turn off but still has to press the button to turn on the case.
B. ATX Computer Power Supply
ATX stands for Advanced Technology eXtended. This types of computer power supply Is equipped with a 20 pin connector, called an ATX power connector. The ATX PSU is used on computers with Pentium III, Pentium IV and AMD CPUs.
Characteristics of ATX PSU:
The power cable for the motherboard consists of 20 pins.
When shutdown the PC will automatically shut down.
Has greater power.
C. BTX Computer Power Supply
BTX stands for eXtended Balanced Technology. This types of computer power supply has 24 pin connectors, called BTX power connectors. It is also equipped with SATA 15 pin power connector. ATX is used on computers Dual core, core 2 duo, Quad core, i3, i5, i7 CPU and the latest AMD models.
Right now, BTX is the most widely used types of computer power supply today. What distinguishes it from the AT PSU is how to install the cable power to the motherboard that is easier and more practical. No need to worry about being reversed, because the type of connector on the cable has been adjusted to the type of slot that is on the motherboard.
Characteristics of BTX PSU:
The power cable for the motherboard consists of 24 pins.
When shutdown the PC will automatically shut down.
There are additional power SATA.
Those are some types of computer power supply that you need to know. So don’t buy wrong PSU, adjust your type and PC.
