InLine 2 Port USB 3.0 Host Controller Card with SATA Auxiliary Power Port PCIe

The InLine 2 Port USB 3.0 Host Controller Card (model 76666L) is a low-profile PCIe expansion card that adds two external USB 3.2 Gen 1 ports to a desktop system. It supports a maximum data transfer rate of 5 Gbit/s and includes a SATA auxiliary power port for stable power delivery to connected devices. The card is compatible with Windows 7 and Windows Server 2008 and is intended for users who need additional high-speed USB connectivity.

Advantages

This USB 3.0 host controller card provides two high-speed USB 3.2 Gen 1 ports via a PCIe interface, enabling transfer rates up to 5 Gbit/s. The integrated SATA auxiliary power port helps supply consistent power to devices that require additional current. The low-profile form factor allows installation in compact cases, and compatibility with legacy Windows systems (Windows 7 and Windows Server 2008) makes it suitable for older setups.

Suitable for

• Adding two external USB 3.0 / USB 3.2 Gen 1 ports to a desktop PC
• Systems requiring stable power for USB devices using the SATA auxiliary power connection

Recommendations

Do not use the website 'Drivers-Download' referenced in some included operating instructions; that site is not affiliated with the manufacturer and has been misused for phishing. Obtain drivers only from official InLine resources or verified vendor sites. Ensure the SATA auxiliary power connector is used when connecting power-hungry USB devices to avoid unstable operation.
