PCIe adapter card with SlimSAS connector and shielded cable to U.2 NVMe port

SMUGDESK

SMUGDESK PCIe 3.0 4.0 SFF-8654 Slimline SAS to SFF-8639 U.2 NVMe Adapter Cable

SKU CH-YF2Z-RWMPR

Connects SFF-8654 SlimSAS host ports to SFF-8639 U.2 NVMe SSDs over PCIe 3.0 and 4.0 x4 lanes with a shielded cable and full-height bracket for secure server installation

  • Supports PCIe 4.0 and 3.0 x4 lanes for full NVMe bandwidth
  • Converts SFF-8654 SlimSAS to SFF-8639 U.2 NVMe without protocol conversion
  • Multi-layer shielding and gold-plated contacts ensure stable signal integrity
  • Standard full-height PCIe bracket secures installation against vibration
  • Designed exclusively for NVMe U.2 SSDs in servers and NAS arrays

PCIe 3.0 & 4.0 SlimSAS U.2 NVMe Adapter

This adapter kit connects a motherboard or HBA controller to an enterprise U.2 NVMe solid-state drive. It combines a PCIe expansion card with a shielded breakout cable for direct signal pass-through. The assembly fits standard full-height brackets for secure mounting inside server chassis. It is built for administrators and DIY builders adding high-speed NVMe storage to rack servers, NAS arrays or workstations.

Suits NVMe-only U.2 drives; not for SATA or SAS

The cable exclusively supports NVMe protocol U.2 SSDs and will not recognise SATA or SAS mechanical hard disks. Buyers needing to attach SATA or SAS drives must choose a different adapter. It serves low-latency database, virtual-machine cluster and high-capacity NAS deployments where pure NVMe performance is required.

PCIe 3.0 & 4.0 x4 lane support

The adapter complies with the PCIe 4.0 specification and remains backward compatible with PCIe 3.0, delivering full x4 lane bandwidth to the connected drive. Multi-layer shielding and gold-plated contacts preserve signal integrity in dense server environments. No protocol conversion occurs, so the drive operates at its native NVMe speed.

Questions about this item

Do I need a motherboard slot that can accept a PCIe card to use this SFF-8654 Slimline SAS to SFF-8639 U.2 NVMe adapter cable?

Yes, the kit includes a PCIe expansion card that must be installed in an available PCIe slot on the motherboard or HBA RAID controller to provide the host connection for the U.2 NVMe SSD.

Can I connect a SATA or SAS mechanical hard drive to the SFF-8639 U.2 port on this cable?

No, the adapter is exclusively for NVMe protocol U.2 solid state drives and cannot identify or operate with SATA or SAS hard disks.

How can I verify the cable is delivering full PCIe 4.0 bandwidth to my U.2 NVMe SSD after installation?

Confirm the drive is detected at PCIe 4.0 x4 link speed in the system BIOS or operating system device manager, indicating the full bandwidth path is active without bottleneck.
