100% Brand New and High Quality Descriptions: Features: By reducing the number of adapters and jumpers, a wire connects directly 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 six. The USB connector is gold-plated to reduce interface interference and improve data integrity. The main control board uses the direct power supply mode of the PCI-E interface and does not require an external power cable. The main control's power supply is not affected by external interference, ensuring 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, significantly improving stability and reliability.
