InLine 76660P Internal U.2 Adapter PCIe Male 4 Gbit/s 3.3 V

The InLine 76660P is a PCI Express expansion card that provides two internal U.2 (SFF-8639) NVMe SSD slots, enabling parallel operation of two 2.5-inch NVMe drives with full PCIe bandwidth. The card uses a PCIe 3.0 x8 connection (up to 64 Gb/s) and supports automatic lane detection (bifurcation) for optimal system integration. LED indicators show read/write activity and operating status. No additional driver is required for native Windows and Linux support. The PCIe board measures 143 mm × 122 mm; verify available space and ventilation in your chassis before installation.

Advantages

The adapter supports two 2.5-inch NVMe SSDs and allows both drives to operate in parallel with full PCIe bandwidth. Automatic lane detection simplifies configuration with motherboards that support PCIe bifurcation. Onboard LEDs provide clear status and activity information. The card is plug-and-play with native support for common Windows and Linux distributions and does not require additional drivers. Power for the U.2 SSDs is supplied via the PCIe bus (3.3 V).

Suitable for

• Systems that need to add two internal U.2 NVMe SSDs
• Workstations or servers requiring high-speed NVMe storage with full PCIe x8 bandwidth
• Setups where motherboard BIOS/UEFI supports PCIe bifurcation (lane splitting)
• Users who want native driverless operation under Windows and Linux

How to use

Install the InLine PCIe card into a free PCIe 3.0 x8 or x16 slot on a compatible motherboard. Secure the card and connect two 2.5" U.2 NVMe SSDs to the SFF-8639 connectors. Ensure the system has adequate chassis space (143 mm × 122 mm) and ventilation. Power for the drives is provided through the PCIe slot; no additional power cables are required. Boot the system and check BIOS/UEFI to confirm device recognition.

Usage recommendations

To operate both U.2 NVMe SSDs simultaneously, enable PCIe bifurcation (lane splitting) in the motherboard BIOS/UEFI if required. The BIOS setting may be named “PCIe Bifurcation”, “Lane Splitting”, or “PCIe Slot Configuration”; consult your mainboard manual for exact instructions. After configuring bifurcation, verify both NVMe drives are detected by the OS.
