Features: Brand new and high quality By reducing the number of adapters and jumpers, a wire is directly connected to the interface, effectively reducing interface interference and line loss, ensuring data reliability, and improving work efficiency. Effectively solves the problem of insufficient PCI-E interfaces on the motherboard, one interface can be expanded to 6. The USB connector is gold-plated to reduce interference between interfaces and improve data integrity. The main control board uses the direct power supply for the PCI-E interface and requires no external power supply. Power is not affected by external interference and has higher stability. The plug-in card design can be directly connected to the motherboard interface without an extension cable and can be connected to the chassis, greatly improving stability and reliability.
