Vszerda NGFF M-Key NVME to SFF-8654 Adapter and U.2 SFF-8639 Cable 50cm

SKU CH-HCWZ-5NB43

Connects an M-Key NVMe drive to a U.2 SFF-8639 port via a SFF-8654 adapter and 50 cm cable, supporting PCIe 3.0 and 4.0

  • Connects M-Key NVMe to U.2 via SFF-8654 adapter
  • Supports PCIe 3.0 and 4.0 for high-speed transfers
  • Includes adapter card and 50cm SFF-8639 cable
  • Designed for NGFF M-Key NVMe and U.2 SSD 750
  • Not compatible with SAS or SATA disks

Adapter and cable kit

This kit converts a mainboard NGFF M-Key NVME slot to an SFF-8654 interface and includes a 50cm U.2 SFF-8639 cable. It supports 4x PCIe 3.0 and PCIe 4.0 connectivity for compatible NVME SSDs. The package contains one adapter card and one cable. It is intended for storage upgrades using this specific interface.

Check your drive and slot

Verify your motherboard has an NGFF M-Key slot wired for NVME PCIe signals before ordering. The adapter does not work with SAS or SATA disks, so the connected drive must be a U.2 NVME SSD. Confirm your operating system is Windows 10 or later for driver support. No other interface standards are supported by this hardware.

Bundled cable enables U.2 connection

The included 50cm cable bridges the adapter card's SFF-8654 port to a U.2 SFF-8639 SSD, allowing the drive to sit away from the motherboard. This cable length suits typical internal routing in standard chassis layouts. The bundle provides the physical link required to use U.2 NVME storage through an M-Key slot. No additional cables or software are included.

Questions about this item

What comes inside the box with this Vszerda NGFF M-Key NVME to SFF-8654 adapter kit?

The package contains one NGFF M-Key NVME to SFF-8654 Slimline SAS card adapter and one 50cm U.2 SFF-8639 NVME PCIe SSD cable.

Which version should I choose to connect a mainboard M-Key NVME drive to a U.2 SSD using PCIe 3.0 or 4.0?

This single version supports both PCIe 3.0 and PCIe 4.0 at 4x lanes for Mainboard NGFF M-Key NVME and U.2 SSD 750 with SFF-8654 interface.

What does the 4x PCIe 3.0 and 4.0 support mean when the adapter is installed in a real system?

It means the adapter passes four lanes of PCIe Gen 3.0 or Gen 4.0 bandwidth between the M-Key slot and the U.2 SFF-8639 connector for NVME SSDs only.
