It features two USB-C and two USB-A ports, all capable of up to 10Gbps data transfer. This card is an ideal solution for adding high-speed USB connectivity without upgrading your motherboard.
Key Features
- Four USB 3.2 Gen 2 ports (10Gbps each): two USB-C and two USB-A.
- PCIe 3.0 x4 interface provides ample bandwidth for simultaneous high-speed transfers.
- Bus-powered design eliminates the need for an external power cable.
- Individual over-current protection on each port for added safety.
- Includes low-profile bracket for installation in compact cases.
Compatibility
- Slot requirement: PCI Express x4, x8, or x16 (physical).

- Connecting high-speed external SSDs or USB flash drives at full performance.
- Expanding USB connectivity for multiple 10Gbps devices.
- A cost-effective alternative to replacing the entire motherboard.
Notes
- Bus-powered ports may not provide enough power for high-draw devices like portable hard drives; use external power for such devices.
- While PCIe 3.0 x4 bandwidth (~4GB/s) is sufficient for four 10Gbps ports, simultaneous full-speed transfers on all ports may approach the interface limit.
