Connects Oculink 4i SFF8611 to U.2 SFF8639 NVMe SSDs with integrated 15-pin SATA power

  • PCIe 4.0 speed with 38-pin Oculink to 68-pin U.2 conversion
  • 15-pin SATA power connector powers NVMe drives without extra cables
  • 50 cm length enables tidy internal routing in servers and NAS
  • Shielded wiring maintains stable high-bandwidth signal transmission
  • Works with enterprise U.2 and U.3 NVMe SSDs and RAID controllers

Oculink 4i to U.2 NVMe adapter

The SMUGDESK CAB861139 converts an Oculink 4i SFF8611 host port to a U.2/U.3 SFF8639 NVMe drive interface. A 15-pin SATA power connector supplies the drive directly from the system power supply. The 50-centimetre shielded cable supports PCIe 4.0 bandwidth for enterprise SSD installations. It targets administrators adding high-performance storage to servers, NAS units or workstations.

Compatibility checks before ordering

Verify that your host provides an Oculink 4i SFF8611 connector with 38 pins and that the target drive uses a U.2 or U.3 SFF8639 interface with 68 pins. Confirm the system can deliver adequate power through a standard SATA power cable to the 15-pin connector on the adapter. Ensure the 50-centimetre length suits your chassis routing without tension or sharp bends.

What the bundled power connector changes

The integrated 15-pin SATA power plug removes the need for a separate drive power cable, reducing cable count inside dense enclosures. Shielded wiring on the data path helps maintain signal integrity at PCIe 4.0 speeds over the full cable run. This single-assembly design simplifies installation in hot-swap backplanes or fixed-mount drive trays where space is limited.

Questions about this item

What connectors come on the CAB861139 cable and do I need any extra power leads?

The cable has a 38‑pin Oculink 4i SFF8611 plug on one end, a 68‑pin U.2/U.3 SFF8639 connector on the other, and a 15‑pin SATA power tail that feeds the NVMe SSD directly — no separate power cable is required.

How do I decide between the available lengths or versions of this adapter?

This model is offered only in a 50 centimetre length with PCIe 4.0 signalling, so there is no alternative length or version to choose from.

What does the PCIe 4.0 rating mean when the cable is installed in a server or NAS?

It indicates the link can run at PCIe 4.0 speeds between the Oculink 4i port and the U.2/U.3 NVMe drive, provided both the host controller and the SSD also support PCIe 4.0.
