Description: 1. Effectively solves the problem of insufficient PCI-E interfaces on the motherboard; one interface can be expanded to 4. 2. Utilizing a plug-in design, it directly connects to the motherboard interface without an extension cable and can be fixed to the chassis, significantly improving stability and reliability. 3. The main control board uses the PCI-E interface's direct power supply mode; no external power cable is required, ensuring the main control board's power is not interfered with externally and has higher stability. 4. Reduces the number of adapters and cables. One cable directly connects to the interface, effectively reducing interface interference and cable loss, ensuring data reliability, and improving work efficiency. 5. USB is gold-plated, reducing interference between interfaces and improving data integrity.
