The Gembird UPC-30-2P is a PCI-Express host adapter designed to add two USB 3.0 ports to your computer, allowing you to connect modern high-speed peripherals to older systems. Built around the NEC D720200F1 chipset, it supports data transfer rates up to 5Gbps, which means you can move large files much faster than with older standards, while remaining fully backward compatible with USB 2.0 and 1.1 devices. This compact card fits into a standard PCI-Express x1 lane or any wider slot, measuring 93 x 121 x 19 mm and weighing only 50 g. To ensure stable power delivery to your connected devices, it utilizes a 4-pin MOLEX power connector. It is a practical choice for users running Windows, MAC OS (Intel-based), or Unix/Linux who need more bandwidth for external hard drives or high-resolution webcams.
