12G SFF-8643 to U.2 NVMe Adapter

This 1.0 metre adapter cable connects a 36 pin SFF-8643 host port to a 68 pin SFF-8639 U.2 NVMe SSD. A 15 pin SATA power receptacle supplies 3.3V and 12V to the drive. The assembly uses a braided sleeve with cloth tape strain relief on both data connectors.

Builders adding U.2 storage to an SFF-8643

Suits DIY upgrades where the motherboard lacks a native U.2 port but an SFF-8643 RAID or HBA card is present. Not for systems that only offer M.2 slots unless a separate M.2 to U.2 adapter is sourced. Buyers needing direct SATA drive attachment should choose a different cable.

PCIe 3.0 x4 over SFF-8639 interface

The single specification that decides fit is the PCIe 3.0 four-lane electrical link carried through the SFF-8639 connector. It supports drives such as the Intel 750 series, P3600 and P3700. Confirm the host card delivers PCIe 3.0 x4 on its SFF-8643 port before purchase.

Questions about this item

Will the 36-pin SFF-8643 connector fit my existing 12G SAS RAID card?

The cable uses a 36-pin HD Mini-SAS SFF-8643 male connector with latch, designed for 12G internal ports on RAID or HBA cards.

How can I verify the U.2 NVMe SSD is detected at PCIe 3.0 x4 speed after installation?

Check the BIOS or OS device manager for a PCIe 3.0 x4 link width and NVMe protocol; the adapter carries four lanes from the SFF-8643 side to the 68-pin SFF-8639 connector.

Does the 1.0m cable include the 15-pin SATA power plug and an M.2-to-U.2 adapter?

The box contains the adapter cable with integrated 15-pin SATA power receptacle; an M.2 to U.2 adapter is not included and must be purchased separately.
