Interface Card Lanberg PCE-US3-004

The Lanberg PCE-US3-004 is an internal PCIe x1 interface card that adds four USB 3.1 Gen 1 (USB 3.2 Gen 1) downstream ports to a desktop computer. It uses a Renesas NEC uPD720201 chipset, provides data transfer rates up to 5 Gbps, and requires a SATA 15‑pin power connection for stable external power. The card comes with a low-profile bracket and supports plug-and-play operation on modern Windows systems.

Advantages

The card delivers USB 3.1 Gen 1 speeds (up to 5 Gbps) while remaining backward compatible with USB 3.0, 2.0 and 1.1, enabling fast file transfers and compatibility with a wide range of USB devices. Its Renesas NEC chipset ensures stable USB host controller performance, and the external SATA power connector supplies reliable power for multiple connected devices. The included low-profile bracket allows installation in small form-factor cases.

Suitable for

• Upgrading a desktop PC to add multiple high-speed USB ports
• Connecting external storage devices such as SSDs and HDDs for faster transfers
• Providing additional USB ports for peripherals (keyboards, mice, webcams not limited by power)
• Installation in small form-factor cases thanks to the low-profile bracket

How to use

Install the card into an available PCIe x1 slot on the motherboard, attach the low-profile or standard bracket as needed, and connect a SATA 15‑pin power cable from the system power supply to the card. After securing the card in the chassis, power on the computer and allow the operating system to detect and install drivers automatically on Windows 8 or later; on older supported Windows versions install drivers if prompted. Connect USB devices to the rear USB ports for immediate use.

Recommendations

Use the SATA power connection when connecting multiple or power-hungry USB devices to ensure stable operation. For optimal transfer speeds, connect USB 3.1 Gen 1 devices using short, high-quality USB 3.x cables and install the card in a PCIe x1 or larger slot to guarantee full bandwidth.
