Adds seven USB 3.0 ports — four Type-A and three Type-C — via a PCIe x1 slot with 5 Gbps transfer speed
This PCIe add-in card adds seven USB 3.0 ports to a desktop computer through a single PCI Express x1 lane. Four ports use the Type-A connector and three use Type-C, all sharing a 5 Gbps bandwidth ceiling. The board draws power directly from the slot so no extra cable is required.
The card suits owners of Windows 7 through 11, macOS 10.8.2 or later, and Linux systems who want more front-panel or rear I/O for peripherals such as drives, cameras or VR headsets. It will not help buyers who need Thunderbolt protocol support or monitor output, and it cannot add ports to a laptop or small-form-factor system without a free PCIe slot.
Because every port funnels through one PCIe 2.0 x1 connection, combined traffic from multiple high-speed drives will contend for the same 5 Gbps ceiling rather than each port delivering that rate independently. The onboard over-current and static protection on each port helps maintain reliable operation during long copy sessions, but aggregate bandwidth remains limited to the single-lane link.
