This PH29A internal USB header converter is a small PCB splitter tailored for DIY desktop PC modification. It expands one motherboard USB2.0 9Pin female header into two independent USB Type-A female sockets, solving the problem of insufficient built-in USB interfaces for connecting multiple internal accessories.
Gold-plated pin contacts offer excellent anti-oxidation and anti-interference performance, maintaining stable data and RGB signal transmission without flickering or random disconnection under long-term chassis vibration. The streamlined PCB layout fits small ITX, MATX and full tower cases without occupying extra internal space.
You can install internal encryption keys, wireless Bluetooth adapters, RGB fan controller modules and LED light strip accessories directly on the dual USB-A ports, saving rear chassis external USB ports for daily external devices.
Simply plug the motherboard 9Pin male header into the splitters female socket, then connect your internal USB/RGB accessories to the dual USB-A ports. Widely used for gaming PC assembly, office workstation upgrades and custom RGB lighting modification for desktops.
