PCIe X1 USB 3.0 Expansion Card, 4-Port 5Gbps PCI Express Hub Controller Adapter with SATA Power & 9.5cm Low Profile Bracket for Desktop Motherboard

This PCI Express X1 expansion card adds four USB 3.0 high-speed ports to your desktop mainboard, solving the problem of insufficient native USB ports. All ports support up to 5Gbps transmission speed, which greatly improves transmission efficiency of U disks, portable hard drives, card readers and other storage devices.

Built with a dedicated SATA power interface, it can directly draw sufficient power from PC power supply, effectively avoiding device disconnection or identification failure caused by insufficient power supply when multiple external hard drives are connected at the same time.

Two brackets are equipped for flexible installation. The matched 9.5cm low-profile half-height bracket perfectly adapts slim ITX, HTPC and small mini chassis, while the full-height bracket fits standard ATX/MATX cases.

The universal PCIe X1 physical interface can be inserted into any idle PCIe expansion slot of Intel and AMD motherboards. With mature onboard controller chip, it keeps stable signal output without speed loss under full load. No complicated configuration required after installing supporting drivers, an economical hardware upgrade for office computers and mini hosts.
