Internal USB 3.0 hub for desktop builders

This EN-Labs hub converts a single motherboard USB 19-pin header into two 20-pin headers, adding four USB 3.0 ports inside the case. It is aimed at system integrators and enthusiasts who need more front-panel or internal connections for drives, peripherals or accessories.

Fits a spare 19-pin header

The 1.3ft cable links the motherboard header to the hub, while an included 4-pin power connector supplies stable current for connected devices. A self-adhesive pad secures the hub to the chassis, freeing expansion slots and keeping cable routing tidy.

Replaces makeshift header splitters

Builders who have exhausted the single USB 3.0 header on their board can gain four ports without occupying a PCIe slot. The upgrade is worthwhile when multiple internal USB 3.0 devices such as card readers, fan controllers or external drive bays must run simultaneously at 5Gbps.
