Features: Excellent high frequency characteristics and stable performance: The PCI-E to Type E expansion card uses high-performance chip capacitors to ensure the high frequency characteristics of the USB3.2GEN1 (formerly USB3.0) power supply. This design enables the expansion card to maintain stability and reliability when handling high-speed data transmission, meeting the needs of users for high-performance devices. Dual protection mechanism to improve security: The expansion card built-in automatic recovery insurance mechanism provides double protection for connected USB devices. When an exception occurs, the device can be protected in a timely and effective manner, which improves security and prolongs the service life of the device. High-speed data transmission improves work efficiency: The product fully complies with the USB3.2 GEN1 (formerly USB3.0) SuperSpeed specification, and the maximum transmission rate can reach 5Gbps, which is nearly 10 times faster than the 480Mb/s of USB2.0. This means that users can transfer large files, high-definition videos, and more faster, significantly improving their productivity and entertainment experience. Wide compatibility and easy connectivity: In addition to support for the USB3.2 GEN1 interface, the product is backward compatible with the USB2.0, USB1.1, and USB1.0 interfaces. This feature ensures that users do not have to worry about device compatibility and can easily connect a variety of new and old devices for seamless data transfer and charging. Stable power supply and flexible use: The product provides up to 5V 1.5A USB power output to ensure stable operation of external devices. At the same time, the PCI-E slot on the mainboard can be converted into A USB3.2 GEN1 TYPE C front-end interface (TYPE-E/A-KEY), which is more flexible and convenient to use. In addition, it also supports USB hot swap function, and users can connect or disconnect the device at any time without shutting down the computer, which is easier to operate.
