The PCIe expansion card adds 8 USB 3.2 ports (6x USB-A, 2x USB-C) to your desktop computer via a PCIe x1 slot, providing enhanced connectivity for multiple USB devices. It supports data transfer speeds of up to 5Gbps, significantly faster than USB 2.0, delivering improved performance for file transfers. Actual transfer speeds may vary depending on the connected device. Each port delivers up to 5W (5V/1A) of power, and the card draws power directly from the PCIe slot—no external power supply is required. The design includes built-in over-current and short-circuit protection to help safeguard connected devices and the host system. Compatible with Windows 7/8/10/11 and macOS 10.8.2 and later, the card fits PCIe x1 to x16 slots (PCIe 3.0 and 2.0 compliant). It features backward compatibility with USB 3.0, USB 2.0, and USB 1.1 devices. Driver installation from the included CD is required for Windows XP and Vista. Equipped with a high-performance Fresco Logic FL1100 chipset, the card ensures stable data transmission and supports UASP protocol, which can improve transfer speeds by up to 70% compared to standard USB 3.0. Note: This card is not compatible with legacy PCI slots. It does not support display output functions such as DP or VGA. The low-profile bracket is not included, making it suitable only for standard or larger chassis. Installation requires a minimum clearance of 4.72 inches in width and 0.51 inches in height.
