Flat Type Dual USB 3.0 Type A Female to Motherboard 20/19Pin Internal Header Adapter PCBA Board for Desktop PC

This flat-form dual USB 3.0 expansion PCBA board comes with two USB 3.0 Type-A female ports and a compatible internal header that works with both 20-pin and 19-pin motherboard USB3.0 slots. The ultra-flat thin profile avoids blocking cooling fans and airflow inside compact PC cases, making it ideal for small ITX builds and tight chassis layouts. Premium gold-plated conductive traces eliminate signal interference and loss, maintaining full USB 3.0 5Gbps transfer speed while delivering reliable power supply to USB drives, RGB fans and other small peripherals. Its universal pin layout resolves compatibility issues between different generations of motherboards with varying USB3.0 header pin counts. Installation is effortless without extra software or tools; just plug the header into your motherboard to instantly add two extra external USB ports. Every circuit board undergoes strict connectivity, signal aging and load testing before shipment to deliver long-lasting stable performance for daily desktop, gaming and industrial host usage.
