The PCI-E plug on the computer power supply is specially designed to provide auxiliary power for independent graphics cards. The PCI-E interface is a relatively common interface standard on motherboards. It is mainly used for devices that need to communicate directly with the CPU. It is usually used to expand functions not supported by the motherboard and make up for the shortcomings of the core display.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The PCI-E plug on the computer power supply is specially designed to provide auxiliary power for independent graphics cards.
The PCI-E interface is a relatively common interface standard on motherboards. It is mainly used for devices that need to communicate directly with the CPU. It is usually used to expand functions that are not supported on the motherboard, such as expanding independent graphics cards, etc. The purpose of the device is to output more powerful graphics capabilities to the platform and make up for the shortcomings of the core display.
Advantages of PCI-E bus
1. PCI-E is a serial bus that performs point-to-point transmission, and each transmission channel has exclusive bandwidth.
2. The PCI-E bus supports bidirectional transmission mode and data channel transmission mode. Among them, the data channel transmission mode is the x1, x2, x4, x8, x12, x16 multi-channel connection of the PCI-E bus. The x1 one-way transmission bandwidth can reach 250MB/s, and the two-way transmission bandwidth can reach 500MB/s.
3. The PCI-E bus makes full use of advanced point-to-point interconnection, switching-based technology, and packet-based protocols to achieve new bus performance and features. Power management, quality of service (QoS), hot-plug support, data integrity, error handling mechanisms, etc. are also advanced features supported by the PCI Express bus.
4. The PCI bus has good inheritance and can maintain the inheritance and reliability of the software. The key PCI features of the PCI-E bus, such as application model, storage structure, software interface, etc., are consistent with the traditional PCI bus.
