75 cm PCIe 4.0 SlimSAS to U.3 Adapter
This 75 cm cable connects a SlimSAS SFF8654 38-pin port to a U.3 SFF8639 68-pin NVMe drive. It serves server, NAS and storage expansion builds that need a long internal link between a RAID controller or backplane and an enterprise U.3 SSD. The integrated SATA 15-pin connector supplies drive power without a separate cable. Builders using shorter chassis or different connector types should choose another adapter.
Shielded construction for signal stability
Premium shielding reduces electromagnetic interference across the full 75 cm run. The design maintains PCIe 4.0 signal integrity for reliable high-speed data transfer under sustained heavy loads. No active cooling or external power regulation is required on the cable itself. Installers routing near noisy components benefit from the shielded layout.
Integrated SATA power simplifies wiring
The built-in SATA 15-pin feed delivers power directly to the U.3 NVMe SSD, removing the need for a separate power lead from the PSU. This reduces cable clutter inside dense servers and high-density NAS units. The single-cable approach speeds up drive swaps and keeps airflow paths clearer. Users whose power distribution relies on different connectors must plan accordingly.

Questions about this item
How do I connect the SFF8654 38Pin end and the SATA power plug during installation?
Plug the SlimSAS SFF8654 38Pin connector into the host controller port, attach the SFF8639 68Pin end to the U.3 NVMe SSD, then connect the integrated SATA 15pin power lead to a standard SATA power cable from the PSU.
Will the SATA 15pin power connector or the SlimSAS cable need periodic replacement?
The cable uses premium shielded construction for longterm heavyload operation; no scheduled replacement is required unless physical damage or connector wear appears during inspection.
At what point does signal integrity become the limiting factor during sustained PCIe 4.0 transfers?
The 75cm length with antiinterference shielding maintains stable PCIe 4.0 signal quality; the practical limit is the host controller or SSD thermal throttle, not the cable itself.
