PCIe x1 to 19Pin/20Pin USB Internal Expansion Card, NEC720200 Chip with IDE 4Pin Power Connector Adapter

This PCI Express x1 expansion adapter card built with mature NEC720200 chip converts spare PCIe x1 slot into internal 19Pin/20Pin USB header, helping users expand front panel USB ports for cases without native headers. It comes with an IDE 4Pin power connector to provide extra power output, effectively solving insufficient power issues that cause USB peripherals to fail recognition or unstable operation. Optimized PCB layout minimizes signal attenuation and electromagnetic interference for long-term steady use. The card supports all mainstream desktop motherboards with PCIe slots and fits standard PC cases with full-height metal bracket.

No complicated driver installation required, plug-and-play under Windows and Linux systems. It is a practical internal USB expansion solution for DIY assembly, industrial hosts and old desktop upgrades.
