Converts one motherboard USB 2.0 header into two USB-A ports with 480 Mbps speed, includes three splitters in vertical and horizontal layouts for flexible chassis wiring

  • Expands one internal USB 2.0 header into two USB-A ports
  • 480 Mbps throughput keeps mouse and flash drives responsive
  • Gold-plated terminals resist oxidation for reliable long-term contact
  • Mixed vertical and horizontal splitters fit tight ITX and full-size chassis
  • Driver-free plug-and-play works with any standard 9Pin F_USB motherboard header

Three-Pack Header Splitter for Internal USB

This three-piece set provides two installation styles — vertical and horizontal — so a single standard 9-pin USB 2.0 motherboard header can be converted into two independent USB-A female ports. It is aimed at system builders and DIY enthusiasts who need extra front-panel or internal USB connections without occupying additional headers.

Practical Limits of the USB 2.0 Interface

The adapter complies with the USB 2.0 480 Mbps specification, so connected devices operate at that maximum signalling rate. Gold-plated terminals resist oxidation for reliable contact, but the splitter cannot deliver more bandwidth or power than the single source header provides, limiting it to mice, flash drives and similar low-power peripherals.

Check Your Motherboard Header Before Ordering

Verify that your board has a standard 9-pin F_USB internal header with the correct pinout; proprietary or keyed headers will not mate with this adapter. The compact PCB fits ITX, MATX and ATX chassis layouts, yet you must confirm enough physical clearance for the chosen vertical or horizontal orientation in your specific case.
