Adds five USB 3.2 ports at 10 Gbps via a PCIe slot, three Type-C and two Type-A
The ESTONE PCIE22A3C3.2 adds three USB-C and two USB-A ports through a single PCI Express slot, giving desktop builders more high-speed connections for drives, cameras and peripherals. It fits x1, x4, x8 or x16 sockets and works with Windows 7 through 11 plus macOS 10.8.2 and later. Driver installation is required on older Windows releases.
Each port supports the USB 3.2 Gen 2 data rate of 10 Gbps, so the card can move large video or image files at the full interface speed when the attached device allows it. The total throughput is shared across all five ports, so simultaneous transfers divide the available bandwidth.
Because the card draws power only from the PCIe slot, continuous high-speed transfers across multiple ports stay within the slot’s delivery limits without extra cables. Actual sustained rates depend on the connected storage or device, but the controller maintains the link speed during extended copy operations rather than throttling after a short burst.

The card supports up to 10 Gbps per port, but the actual transfer speed is limited by the connected device and the PCIe lane width used.
It complies with PCIe 3.0 and 2.0 and fits x1, x4, x8 or x16 slots; bandwidth is limited by the slot generation and lane count.
It fits any PCI Express x1, x4, x8 or x16 socket and includes installation screws for securing the bracket.
