Effectively solve the problem of insufficient pci-e interfaces on the motherboard, one interface can be expanded to 4. The plug-in card design can be directly connected to the motherboard interface without an extension cable, and can be connected to the chassis, which significantly improves the stability and reliability. The main control board adopts the direct power supply mode of the pci-e interface, and does not require an external power cord. The main control power supply is not affected by external interference and has higher stability. By reducing the number of adapters and , one wire is directly connected to the interface, effectively reducing interface interference and line loss, ensuring data reliability and improving work efficiency. The USB connector is gold-plated to reduce interference between interfaces and improve data integrity. Added BIOS, greater compatibility with motherboards and graphics cards, and lower power consumption.
