Adds eight USB 3.2 Gen 2 ports — four Type-C and four Type-A — at up to 10 Gbps through a PCIe x1 slot
This ESTONE expansion card adds four USB-C and four USB-A ports to a desktop computer through a single PCI Express x1 lane. It targets builders who need more high-speed external connections for drives, peripherals or streaming gear without occupying additional slots. The card draws power directly from the PCIe slot so no extra power cable is required.
Ports are oriented vertically on a board measuring 4.76 inches long with USB-A ports standing 0.71 inches tall, which prevents installation in 1U or 2U chassis and other compact enclosures. Windows 11, 10, 8, macOS 10.8.2 and newer, Linux and unRAID operate without extra drivers; Windows 7 and XP need the supplied RENESAS/VLI driver from the included CD.
All eight ports share the single PCIe x1 Gen 3.0 or 2.0 link, so aggregate throughput cannot exceed the lane's 10 Gbps ceiling and actual speeds depend on each attached device. The card fits x4, x8 or x16 slots but Dell motherboards running Windows 10 or 11 may exhibit recognition issues. No low-profile bracket is supplied.

It runs in a PCI Express x1 lane and supports PCIe 3.0, 2.0 and 4.0 motherboards; the 10 Gbps USB 3.2 limit is set by the controller, not the slot.
Overall length is 4.76 in with USB-A ports at .71 in height; no low-profile bracket is included, so it does not fit 1U or 2U cases.
Insert into any x1, x4, x8 or x16 slot, secure with the supplied screw, then install the RENESAS/VLI USB 3.2 driver from the included CD before connecting devices.
