Key benefits Adds speed USB functionality to a compatible desktop via a PCIe slot using the uPD720202 controller. Solves limited or aging USB ports by providing additional USB connectivity and improved data transfer for external drives and peripherals. Compact design with small powerconnector options minimizes space and power cabling changes while keeping performance stable. What this product does PCIe USB expansion card based on the uPD720202 controller, delivering USB connectivity for systems that accept a PCIe standard card. Requires insertion into a PCIe slot and an external power connection to operate. Important compatibility and requirements Only use with PCIE standard. The card must be installed in a PCIe slot on the motherboard. Must be plugged in to function when in use — the card requires a power connection to the system. Power supply options: Small PCIE 15PIN or Floppy Drive Small 4PIN Power Supply. Hardware whitelist: The brand has added a whitelist hardware mechanism. You can search for the white list of USB ports to confirm compatibility with your system's USB configuration. Driver and OS support: uPD720202 compatible with Windows XP / 2003 / 2008 / 7 / 8 / 10 / 11, 32bit and 64bit. Key attributes Function: Provides additional USB ports via PCIe using the Renesas uPD720202 controller. Compatibility: Works with PCIestandard slots and the listed Windows operating systems; verify whitelist for USB port compatibility. Size: Compact PCIe form factor suited for small or standard desktop cases; uses small power connector options as specified. Performance: USB controllergrade performance appropriate for external storage, peripherals, and other USB devices supported by the controller and OS drivers. Reliability: Requires proper power connection and PCIe installation for stable operation. Practical use scenarios Expand a desktop PC that lacks native USB 3.0 ports to support faster transfers for external SSDs and backup drives. Add USB connectivity to older systems running Windows XP/2003/2008 where native USB performance or port quantity is insufficient. Provide additional ports for docking multiple USB peripherals (keyboard, mouse, camera, external drives) in systems that have an available PCIe slot and the required power connector. Installation notes and recommendations Confirm your motherboard has an available PCIe slot and that your case allows a standard PCIe card installation. Connect the Small PCIE 15PIN or Floppy Drive Small 4PIN power cable as required; the card will not operate without this power connection. Before or installation, search the brand's whitelist for supported USB ports to ensure full compatibility with your system configuration. Install appropriate drivers for the uPD720202 controller for the listed Windows versions (XP through Windows 11, 32/64bit) to ensure performance. No modifications have been made to the original specifications: PCIeonly card, requires power connection, whitelist hardware mechanism present, Small PCIE 15PIN or Floppy Drive Small 4PIN power supply options, and uPD720202 support for Windows XP/2003/2008/7/8/10/11 32/64bit.
