Adds four USB 3.0 ports (two Type-A, two Type-C) to a desktop via a PCIe x1 slot, delivering up to 5 Gbps total bandwidth without an external power cable
This PCIe expansion card adds four USB 3.0 ports to a desktop computer using a single PCIe x1 slot. It provides two USB Type-A and two USB Type-C ports for connecting peripherals such as external drives, audio interfaces, or VR sensors. The card is compatible with PCIe x1, x4, x8, and x16 slots. It supports 32-bit and 64-bit versions of Windows 11, 10, 8, 7, and XP as well as Linux.
The card fits any standard PCIe slot from x1 to x16 without requiring an external power cable from the PSU. It draws power directly from the slot and supplies up to 5V/1.5A per port. A Fresco FL1100 host controller manages the four ports, and each port has its own circuit protector. No driver is needed for Windows 10 or 11; a driver CD is included for older operating systems.
Each port can reach a theoretical 5 Gbps when used alone, with total bandwidth shared across all four ports. The card handles data transfer only and does not support PD fast charging, video output, or Thunderbolt protocol. It is backward compatible with USB 2.0 and 1.1 devices. Mac OS is not supported.

The card shares a single 5 Gbps PCIe 2.0 x1 lane across all four ports, so simultaneous transfers divide that throughput.
Solid capacitors and the 4‑ampere protection circuits keep the controller at low temperature during sustained loads.
Yes, the card fits any PCIe x1, x4, x8 or x16 slot and operates at x1 electrical width.
