Connector Conversion for U.2 and U.3 Drives
This adapter adds an OCuLink SFF-8612 female port to an existing SFF-8639 U.2 or U.3 interface. It includes a SATA power connector supplying 5V and 12V for drive operation. The card is designed for motherboards or backplanes with a compatible U.2/U.3 slot.
Suits Builders Adapting Existing U.2/U.3 Slots
It fits systems where a U.2 or U.3 port is present but an OCuLink SFF-8612 connection is required. Builders needing to connect a drive directly to an M.2 slot, a standard SATA port, or a PCIe slot without a U.2/U.3 interface should look elsewhere.
Passive PCIe 4.0 and 5.0 Signal Path
The adapter transmits PCI Express 4.0 and 5.0 signals using the NVMe protocol at up to 64Gbps. It supports NVM Express 1.2 and operates transparently without drivers. The vertical connector orientation eases installation where space around the port is limited.

Questions about this item
How do I install the SFF-8612 to SFF-8639 adapter and connect the SATA power cable?
Plug the OCuLink SFF-8612 female connector into the host port, attach the SFF-8639 U.2/U.3 female side to the drive, then connect the SATA power cable to a 5V+12V supply from the mainboard. The vertical SFF-8612 connector fits tight spaces. No drivers are required.
What maintenance or replacement will the adapter need over time?
The adapter has no moving parts and requires no scheduled maintenance. If the copper conductors or SATA power cable show physical damage or intermittent contact, replace the unit.
What is the first limit I will hit under sustained PCIe 5.0 NVMe loads?
The link tops out at 64Gbps using the NVMe 1.2 protocol, so sustained throughput cannot exceed that ceiling regardless of drive capability.
