ST684 USB3.0 19Pin to USB3.1 Type-E 20Pin Header Adapter, Motherboard Internal Connector Converter for Chassis Front USB Type-C Expansion

The ST684 motherboard internal header adapter perfectly resolves the compatibility conflict between old motherboards with standard USB3.0 19Pin internal headers and new PC cases equipped with USB3.1 Type-E 20Pin front-panel Type-C cables, enabling you to use the chassis front USB-C port without replacing your motherboard.

Built with precision multi-layer PCB and standard pin mapping, this adapter maintains full USB3.2 Gen1 5Gbps bandwidth for fast file copying, external SSD connection and peripheral data transmission. The optimized differential signal traces effectively reduce electromagnetic interference from power supplies and cooling fans, ensuring steady and error-free signal output.

Ultra-small slim structure occupies minimal space on the motherboard, and will not interfere with RAM sticks, GPU PCIe slots or other adjacent internal connectors, ideal for compact mini ITX and MATX small chassis builds. Plug-and-play design requires no extra drivers or software, compatible with all mainstream desktop motherboard brands including ASUS, MSI, Gigabyte, ASRock, ZOTAC and Biostar.

Suitable for DIY PC builders, hardware modders and office desktop assembly. It is a cost-effective upgrade accessory to activate front panel USB-C connectivity and enrich your desktop expansion options.

Note: This adapter only supports USB3.2 Gen1 5Gbps speed, does not support USB PD fast charging and USB3.2 Gen2 10Gbps bandwidth.
