Effectively solve the problem of insufficient PCi-E interfaces on the motherboard, and 1 interface can be expanded to 4.The plug-in design is adopted, which can be directly inserted into the motherboard interface without extension cable, and can be fixed on the chassis, which greatly improves the stability and reliability.The main control board adopts the PCI-E interface direct supply mode, no external cord is required, so that the main control board supply is not disturbed by the outside world, and the stability is higher.Reduce the number of adapters and adapters, one line directly to the interface, effectively reduce interface interference and line loss, data reliability, and improve work efficiency Fast startup, loading and file transfer. Low consumption, quiet, reliable and durable.Name: PCI-E 1 to 4 Riser CardInterface: PCI-E USB3.0System: Support WINXP, WIN7, WIN8, WIN10, LINUX DOStype:v016 proColour:blackMaterial:PCBPackage Contents:1 x Pcie 1 To 4 Adapter4 x PCI-E 16X Riser Board4 x USB Cable(random colors, don't accept the specified color) 4 x SATA 15 Pin To 6 Pin CableDifferent production batches, the color of PCIE16X card slot and USB cable may be different, but it does not affect the useOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
