PCI-E 1X multi-interface card solve the situation that the desktop computer PCI-E 1X is not enough.
But even with USB 3.0, the theoretical bandwidth is only 5 Gbps (625 MB/s), and the loss is only 150 MB/s in four minutes, and even the single channel bandwidth of PCI-E 1.x is 250 MB/ s, so this can give you the most slots, but not enough bandwidth, onl
The device card is used for transfer between PCI-E and PCI-E.
It consists of two parts, one is the main card, installed on the motherboard through the PCI-E x1 interface, and the other is the device card, which has three or four PCI-E x1, which are connected by USB 3.0 cable.
The slot on the motherboard can be directly led out from the slot or placed on the slot connection board connected to the chassis.
