InLine 76660O Internal U.2 Adapter PCIe Male 4 Gbit/s

The InLine PCI Express card adds two internal U.2 NVMe SSD slots to a PC and enables parallel operation of two 2.5-inch NVMe drives with full PCIe bandwidth. The card uses a PCIe 3.0 x8 interface with automatic lane detection (bifurcation) for optimum system integration and provides LED indicators for read/write activity. No additional driver is required; native Windows and Linux support is provided.

Advantages

The adapter supports two 2.5-inch NVMe SSDs in SFF-8639 (U.2) format and delivers up to 64 Gb/s total bandwidth via a PCIe 3.0 x8 connection, with each port supporting up to 4 GB/s. Automatic lane detection configures the slot for correct bifurcation, and onboard LEDs make fault diagnosis and status monitoring easier. The U.2 drives are powered directly from the PCIe bus, eliminating the need for separate power cables.

Suitable for

• Adding two internal U.2 NVMe SSDs to a desktop PC
• High-speed storage expansion where full PCIe bandwidth is required
• Systems that support PCIe bifurcation for parallel NVMe operation

Key specifications

• Interface: PCIe 3.0 x8 (8 GT/s), up to 64 Gb/s total bandwidth
• Connectors: 2 x SFF-8639 (U.2) for 2.5-inch NVMe SSDs
• Per-port data rate: up to 4 GB/s
• Chipset: PI6C20400BLE
• Board dimensions: 236 mm x 87 mm
• Operating temperature: -40 °C to +85 °C
• Power: U.2 SSDs powered via PCIe bus (3.3 V)

How to use

Install the card into a free PCIe 3.0 x8 or x16 slot on a compatible motherboard. Mount 2.5-inch U.2 NVMe SSDs into the SFF-8639 connectors and secure them with the supplied screws. If your motherboard requires it, enable PCIe bifurcation (lane splitting) in the BIOS/UEFI so the x8 slot is divided (for example into two x4 channels) and both NVMe devices can operate simultaneously. After hardware installation, boot the system and verify that both NVMe drives are detected by the operating system. No additional driver installation is necessary for supported Windows or Linux distributions.

Usage recommendations

Consult your motherboard manual for the exact BIOS/UEFI options and terminology (e.g., "PCIe Bifurcation", "Lane Splitting", or "PCIe Slot Configuration"). Ensure the PCIe slot supports bifurcation and that your operating system version is listed among supported releases before deploying the adapter in production environments.
