20gbps high-speed transmission. Some users can easily experience 20gbps high-speed transmission in the form of expansion card if they use the low-end motherboard without usb3.2gen 2x2 interface. Using the latest USB3.2 Gen 2X2 interface, the transmission bandwidth is up to 20Gbps. After connecting USB3.2 peripheral devices, it can not only maintain compatibility with existing USB peripheral devices, but also allow your desktop to achieve high-speed data transmission, thereby improving work efficiency. The PCIe x4 interface design also supports PCI Express X4, X8, and X16 channels. to PCI slots. Delivery of short iron pieces, large and small cases can be used.
