InLine 76660T Internal M.2 mSATA PCIe Adapter

The InLine 76660T Internal M.2 mSATA PCIe Adapter is a multifunctional PCIe 3.0 x16 expansion card that supports installation of M.2 NVMe (Key M), M.2 SATA or NVMe in SATA mode (Key B) and mSATA modules. It provides onboard LED indicators for status monitoring and requires a motherboard with PCIe and SATA support to connect M.2 SATA and mSATA drives via separate SATA connectors.

Advantages

The adapter combines three storage interfaces on a single PCIe card, enabling flexible use of different SSD types without additional drivers. NVMe drives in the Key M slot receive power directly from the PCIe bus, while M.2 SATA and mSATA modules connect to the motherboard through included SATA cabling. The card supports standard M.2 sizes and both half- and full-size mSATA modules, and features automatic lane detection at boot for compatibility.

Suitable for

• Upgrading desktop PCs and servers that have a free PCIe 3.0 x16 slot
• Systems requiring a mix of NVMe and SATA-based M.2 or mSATA storage
• Environments where compact multi-drive expansion is needed without additional controllers

Key specifications

• Bus type: PCIe 3.0 x16
• Slots: 1 x M.2 Key M (NVMe PCIe), 1 x M.2 Key B (M.2 SATA or NVMe in SATA mode), 1 x mSATA
• SATA connectors: 2 x 7-pin SATA 6 Gb/s for M.2 SATA and mSATA connection
• Supported M.2 sizes: 2230, 2242, 2260, 2280; mSATA: half and full size
• Data rates: NVMe (Key M/B+M) up to 4 Gb/s; M.2 SATA & mSATA up to 6 Gb/s (via SATA)
• Dimensions: 169 mm x 68 mm
• Operating temperature: -40 °C to +85 °C
• Power: NVMe via PCIe bus (3.3 V); M.2 SATA/mSATA via motherboard SATA connection

How to use

Install the card into an available PCIe 3.0 x16 slot on the motherboard. Mount compatible M.2 or mSATA modules into their respective slots and secure them with screws and heat pads if provided. Connect the included SATA cable from the card’s SATA connector(s) to the motherboard for M.2 SATA and mSATA modules. After assembly, boot the system; the card detects lane configuration automatically and onboard LEDs indicate interface status. No additional driver installation is required for supported operating systems.

Usage recommendations

Ensure the motherboard BIOS supports NVMe and SATA over PCIe and confirm there is physical space for the card and cabling. Use the supplied low-profile bracket if installing in small-form-factor cases. For optimal thermal behaviour, apply the provided heat conduction pads where necessary and maintain adequate airflow around installed SSDs.
