Adds five USB 3.0 ports — three Type-A and two Type-C — through a PCIe x1 slot at up to 5 Gbps
This PCI Express x1 card adds three USB-A and two USB-C ports to a desktop, delivering up to 5.0 Gbps total bandwidth for external drives, cameras and peripherals. It suits builders who need more front-panel connectivity without using a drive bay. The board works with Windows 7 through 11 and Mac OS 10.8.2 or later.
The card draws power directly from the slot and provides up to 5 V at 12 A combined across all ports, so high-draw devices such as drive enclosures run without an external adapter. No fan or heatsink is fitted, so operation is silent and heat output stays low during typical file transfers.
Each port can supply 5 V at 3 A maximum, and the onboard controller maintains the 5.0 Gbps link during long copy sessions. The card does not support Power Delivery fast charging or video output, so it is not for users who need display or rapid-charge functions over USB-C.

Insert the card into any PCI Express x1, x4, x8 or x16 slot, then install the RENESAS/VLI USB 3.0 driver from the included CD before use; Windows 10 and Mac OS 10.8.2+ do not need the driver.
No scheduled maintenance is required; the card draws power from the slot with four onboard power modules delivering up to 5V/3A per port, and has no fan or battery to replace.
The PCI Express 2.0 x1 lane caps total bandwidth at 5 Gbps, so all five ports share that ceiling when multiple devices transfer simultaneously.
