If you need more than one PCI-E x1 slot and don't have that many on your motherboard, then you can consider this adapter card. It consists of two parts, one is the main card, which is installed on the motherboard via the PCI-E x1 interface. The second is the device card, which has three or four PCI-E x1 strips on it and the two are connected together via a USB 3.0 cable. The device card is used for the transfer between PCI-E, PCI-E.
Interface: Motherboard PCI- E IX (1X, 4X, 8X, 16X compatible). Product speed: PCI-E2.0.
2U case: Support, can be used with half height baffle, full height baffle sent by default.
The PCI-E slot being transferred should preferably be version 2.0 or above, and version 3.0 is even better. And is only suitable for places where performance is not required.
Because WINS limits the number of graphics cards, under WIN10 you can only recognise up to 8 cards, WIN7 can only recognise 6 cards and you have to use a modified version of the graphics card driver and try to use the same model of graphics card on a motherboard.
