Adds three USB-C and two USB-A ports at 5 Gbps through a single PCIe slot
The ESTONE PCIE22A3C adds three USB-C and two USB-A ports through a single PCI Express x1 slot. It suits desktop owners who need more SuperSpeed connections for peripherals such as external drives, VR headsets or cameras without replacing the motherboard.
Windows 10 and Mac OS 10.8.2 or later work without extra drivers; Windows 7, XP and Vista require the supplied RENESAS/VLI driver from the included CD. The card draws all power from the PCIe slot, so no auxiliary power connector is needed.
A driver CD, mounting screws and a user manual are provided in the box. The disc contains the legacy driver required for older Windows versions, while the screws secure the bracket to the chassis and the manual illustrates the slot insertion steps.

Insert the card into any PCI Express x1, x4, x8 or x16 slot, secure it with the supplied screw, then install the RENESAS/VLI USB 3.0 driver from the included CD before connecting devices; the driver step is the one most often overlooked.
No scheduled maintenance is required; if a port becomes loose or the controller fails, the entire add-in card is replaced as a single unit.
The shared PCI Express x1 lane caps total bandwidth at 5.0 Gbps, so sustained transfers across multiple ports will hit that ceiling before individual device limits.
