Vszerda NGFF M-Key NVMe to SFF-8654 & U.2 SFF-8639 SAS Cable

SKU CH-QK7S-6D1A2

Connects an M-Key NVMe drive to SFF-8654 and U.2 SFF-8639 ports using a 50 cm cable, supporting PCIe 3.0 and 4.0 on Windows 10 or later

  • Connects M-Key NVMe drives to SFF-8654 Slimline SAS
  • Includes adapter card plus 50 cm U.2 SFF-8639 cable
  • Supports PCIe 3.0 and PCIe 4.0 at 4x lanes
  • Designed for mainboard NGFF M-Key NVMe and U.2 SSD 750
  • Incompatible with SAS or SATA disks

Adapter Purpose & Audience

This adapter connects an NGFF M-Key NVMe SSD to a mainboard SFF-8654 Slimline SAS port or a U.2 SFF-8639 bay. It targets builders adding high-speed NVMe storage to server or workstation boards that expose those enterprise connectors.

Upgrade Path & Value

It replaces direct M.2 mounting when the board lacks an M-Key slot but provides SFF-8654 or U.2 interfaces. The jump is worth it when you need to reuse an existing NVMe drive in a system wired for enterprise backplanes.

Fit & Limits

Suits technicians integrating consumer NVMe SSDs into Hyper Kit Storage controllers or similar PCIe 3.0 and 4.0 backplane environments. Not for users needing SAS or SATA drive support, nor for boards without the specified SFF-8654 or SFF-8639 connectors.

Highlights

  • Connects M-Key NVMe drives to SFF-8654 Slimline SAS

  • Supports PCIe 3.0 and PCIe 4.0 at 4x lanes
  • Designed for mainboard NGFF M-Key NVMe and U.2 SSD 750
  • Incompatible with SAS or SATA disks

Questions about this item

What M-Key slot length and connector does the adapter card require on the motherboard?

The adapter fits a standard NGFF M-Key NVMe slot on the mainboard.

Which side of the 50 cm cable plugs into the adapter card and which side connects to the U.2 drive?

Insert the SFF-8654 end into the adapter card and the SFF-8639 end into the U.2 NVMe SSD; the cable only fits one way.

Does the cable or adapter need any firmware updates or driver maintenance after installation?

No firmware or driver maintenance is required; the adapter operates with the native PCIe 3.0 and 4.0 support in Windows 10 or later.
