#1	The slot on the motherboard can be directly led out from the slot or placed on the slot connection board connected to the chassis
#2	PCI E 1X multi interface card solve the situation that the desktop computer PCI E 1X is not enough
#3	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 30 cable
#4	The device card is used for transfer between PCI E and PCI E
#5	But even with USB 30 the theoretical bandwidth is only 5 Gbps 625 MBs and the loss is only 150 MBs in four minutes and even the single channel bandwidth of PCI E 1x is 250 MB s so this can give you the most slots but not enough bandwidth onl
