Adds eight USB 3.2 ports — four Type-C and four Type-A — at up to 10 Gbps through a PCI Express slot
This PCI Express add-in card adds four USB-C and four USB-A ports to a desktop system. It fits x4, x8 or x16 slots and draws power directly from the slot without extra cables. The board suits users who need many high-speed ports for external drives, peripherals or media workflows. It is not for builders who require a low-profile bracket for 1U or 2U chassis.
Each port supports up to 10 Gbps, but real-world throughput depends on the attached device and total bus load. The single PCIe lane limits aggregate bandwidth when all eight ports are active simultaneously. Heavy multi-drive copies will share the available lane rather than run at peak speed on every port.
The card operates on PCI Express 2.0 or 3.0 x1 electrical width, so total throughput cannot exceed that lane's capacity. Its 4.76-inch length and .71-inch port height prevent installation in small-form-factor or rackmount cases. Driver installation is required for Windows versions before 10 and for Mac OS 10.8.2 or later.
