DiLinKer PCIe 5.0 MCIO x4 to U.2 NVMe Adapter, SFF-TA-1016 to SFF-8639 Cable with Power, Cable 70cm

Attach a U.2 (SFF-8639) NVMe drive directly to an MCIO header. This PCIe 5.0 assembly starts with an MCIO 4x connector (SFF-TA-1016, 38-pin) and ends in a U.2 drive interface, with a power branch built into the cable so one part does the whole job. It is the shortest path from a Gen5 board’s MCIO x4 headers to 2.5-inch U.2 NVMe SSDs — no adapter card, no backplane.

Why this cable

• PCIe 5.0 rated. A full x4 link at 32 GT/s per lane — about 15.75 GB/s to a Gen5 U.2 SSD.
• Direct drive attach. Reaches the U.2 drive itself; no backplane or adapter card in between.
• Power built into the assembly. The cable carries the drive power branch, so you do not need a separate U.2 power adapter.
• 70 cm of reach. Comfortable routing from board headers to a 2.5-inch drive bay.
• Passive assembly. No firmware, no driver, nothing to configure.

Specifications

Compatibility

Works with

• Boards with MCIO 4x (SFF-TA-1016) 38-pin headers carrying PCIe.
• 2.5-inch U.2 (SFF-8639) NVMe SSDs, Gen4 and Gen5.
• Server and workstation chassis with standard drive power (SATA-style or MOLEX via the branch).

Does not work with

• U.2 drives behind a backplane — for that, run an MCIO cable to the backplane port instead.
• M.2 slots — this is a U.2 (2.5-inch) assembly.
• SAS/SATA U.2 drives behind SAS hosts — NVMe requires a PCIe-capable host port.

Typical deployments

• Gen5 board to U.2 SSD. The direct MCIO-to-drive run on current platforms.
• Front bay NVMe. Feed a 2.5-inch bay from an MCIO header without a backplane.
• Lab benches. Quick U.2 device attach for testing Gen5 SSDs.

Frequently asked questions

Do I still need a separate power cable for the drive?

No. The assembly includes the power branch, so the drive’s power comes along with the data cable from a standard internal power source.

Will it run a Gen4 U.2 SSD?

Yes. The link negotiates to the device speed, so Gen4 and Gen3 drives run at their rated rates.

MCIO x4 or x8 — which do I have?

The 38-pin plug is x4, the 74-pin plug is x8. This cable is x4; if your header is the 74-pin type, use the MCIO x8 to 2×U.2 NVMe cable instead.

Does the drive need to be NVMe?

For PCIe hosts, yes — U.2 SAS drives will not enumerate on a PCIe port. The cable itself is passive and carries whatever the host and drive agree on.
