Effectively solve the problem of insufficient pci-e interfaces on the motherboard, and one interface can be expanded to four.The plug-in design allows you to directly connect to the motherboard interface without an extension cord, and can be connected to the chassis, which significantly improves stability and reliability.The main control board adopts the direct power supply mode of the pci-e interface, and no external power cord is required. The main control power supply is not affected by external interference and has higher stability.By reducing the number of adapters and jumpers, 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.BIOS has been added, which is more compatible with motherboards and graphics cards, and has lower power consumption.Bus interface: PCI-E X1 (compatible with X4, X8, X16 graphics interface)Number of interfaces: PCI-E X1, USB 3.0x4, molex 4 Pin Power portMaterial:PC+metalcolour:BlackPackage Contents:1 x PCIe AdapterOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
