ATX power supply is a common computer power supply, which uses standardized interface types and protection mechanisms to ensure the stable operation and security of computer systems. The ATX power supply has adopted a new design concept, which has greatly improved its energy efficiency, stability, safety, and other aspects. In addition, the ATX power supply also has a more user-friendly design, such as support for soft shutdown, automatic adjustment of fan speed, and other functions. This article will introduce the interface type and protection mechanism of the ATX power supply.
Here is the content list:
Interface type
Protection mechanism
1. Mainboard power interface
The motherboard power interface is one of the most important interfaces for ATX power supplies, providing all the power required by the motherboard. This interface typically includes 20 or 24 pins, including different voltage outputs such as +3.3V, +5V, +12V, -12V, and +5 Vsb. These outputs can provide the required energy for components such as the CPU, memory, and hard disk.
2. SATA power interface
The SATA power interface is an interface used to connect devices such as SATA hard disks and optical drives. This interface typically includes 15 pins, including different voltage outputs such as +3.3V, +5V, and+12V. These outputs can provide the required energy for SATA devices.
3. Molex power interface
The Molex power interface is used to connect devices such as IDE hard disks and optical drives. This interface typically includes four pins, including different voltage outputs such as+5V and+12V. These outputs can provide the required energy for the IDE device.
4. PCI-E 6/8pin power interface
The PCI-E 6/8pin power interface is an interface used to connect devices such as high-performance graphics cards. This interface typically includes 6 or 8 pins, including different voltage outputs such as+12V. These outputs can provide the required energy for the graphics card.
1. Overload protection
Overload protection is one of the most basic and important protection mechanisms in ATX power supplies. When the system load exceeds the ATX power supply rating, overload protection automatically shuts down the system to prevent damage.
2. Short circuit protection
Short circuit protection means that when a short circuit occurs in the system, the ATX power supply will automatically turn off to prevent damage. This can happen on the motherboard or other components.
3. Overvoltage protection
Overvoltage protection refers to the automatic shutdown of the ATX power supply to prevent damage when excessive or abnormal high voltage occurs in the system. This can happen on the motherboard or other components.
4. Under voltage protection
Under voltage protection refers to the automatic shutdown of the ATX power supply to prevent damage when a low voltage occurs in the system that is below the normal operating range. This can happen on the motherboard or other components.
The above is an introduction to ATX power supply. When using a computer, we need to pay attention to the above points, avoid problems when using the computer, and promptly handle them to better use the computer.
