Product Description: Expansion Cards PCIE to USB 3.0 19/20 Pin Interface Riser Card Upgrade your PC's connectivity and performance with our Expansion Cards PCIE to USB 3.0 Riser Card. Designed for compatibility with X4, X8, and X16 slots, this riser card is perfect for enhancing your system's USB capabilities while ensuring high-speed data transmission and reliability. High-Speed Data Transmission: This riser card utilizes the PCI-Express interface through the VL805 master bridge, providing four USB 3.0 ports for high-speed data transfer. Enjoy lightning-fast connectivity for your devices, making it ideal for data-intensive applications such as gaming, video editing, and large file transfers. Reduced Rectifier Loss: Our synchronous rectifier employs a power MOSFET with very low on-state resistance, replacing traditional rectifier diodes. This innovative design minimizes rectifier loss, enhances the efficiency of the DC/DC converter, and meets the demands of low voltage and high current applications, ensuring optimal performance. Durable and Efficient Design: Crafted from low-loss alloy powder die casting, this riser card features low impedance and minimal parasitic capacitance. Its compact size does not compromise on performance, allowing for large current handling while ensuring durability and rust prevention for long-lasting use. Safety Features with Self-Recovery Fuse: Each 19p and 20p output port is equipped with a self-recovery fuse. In the event of an external short circuit, the fuse melts instantly to create a high block open state, limiting the short circuit current. Once the fault is resolved and the temperature drops, the fuse automatically resets, restoring normal operation without the need for manual intervention. High Performance and Reliability: With high gold plating, this riser card offers excellent oxidation resistance, ensuring good conductivity and wear resistance. This means you can rely on consistent performance over time, making it a valuable addition to your PC setup. Enhance your computer's functionality and performance with the Expansion Cards PCIE to USB 3.0 Riser Card. Whether you're upgrading your gaming rig or expanding your workstation, this riser card provides the speed, efficiency, and reliability you need for all your USB devices.
