Adds five USB 3.2 ports — three Type-C and two Type-A — at up to 10 Gbps through a single PCI Express slot
The ESTONE PCIE22A3C3.2 adds three USB-C and two USB-A ports to a desktop through a single PCI Express x1 lane. It targets users who need more high-speed data connections for drives, peripherals or VR headsets without occupying rear motherboard headers. The card draws power directly from the slot and requires no external cable.
Installation uses a standard low-profile bracket and the supplied screws. Driver installation is needed for Windows 7, 8 and 10 32/64-bit; Windows 11 and Mac OS 10.8.2 or later typically work without extra software. Each port delivers up to 5 V at 1 A for bus-powered devices.
Under sustained multi-device transfers the onboard protection isolates faults without shutting down the whole card. Real-world throughput stays at the connected device's limit, while the 10 Gbps link remains stable during long copy sessions or continuous camera capture.

The card uses a single PCIe lane at 3.0 or 2.0 speed, so combined throughput is limited to that lane's bandwidth rather than 10 Gbps per port.
It draws power from the PCIe slot only, each port is capped at 5 W with per-port over-current protection, and no external power connector or fan is required.
The card fits any PCIe x1, x4, x8 or x16 slot running at 3.0 or 2.0 and works with Windows 7 through 11 and Mac OS 10.8.2 or later.
