Vszerda Mini SAS SFF-8643 to U.2 SFF-8639 NVMe Adapter Cable with SATA Power .5m

SKU CH-1MSE-2HFNP

Connects a U.2 NVMe SSD to a Mini SAS SFF-8643 controller with integrated SATA power over a .5 m cable

Cable Length 0.5m

  • Connects U.2 NVMe SSDs via Mini SAS SFF-8643 interface
  • Supports Intel SSD 750 P3600 P3700 drives
  • 50cm length with integrated SATA power connector
  • 12G HD Mini SAS design for high-speed data transfer
  • Braided sleeve jacket with cloth tape strain relief

Connect U.2 NVMe SSDs via Mini SAS

This adapter cable bridges a Mini SAS HD SFF-8643 port to a U.2 SFF-8639 NVMe SSD, adding high-speed storage capability when the motherboard lacks a native U.2 connector. It supports drives such as the Intel SSD 750, P3600 and P3700 series. The .5 metre length suits compact builds and tidy cable routing.

Requires a compatible RAID

The SFF-8643 end plugs into a PCIe add-in card — for example an ASRock U.2 card or Gigabyte M.2-to-U.2 adapter — while an integrated SATA power lead draws 3.3 V and 12 V from the PSU to run the SSD. No M.2 drive can attach directly; a separate M.2-to-U.2 adapter would be needed for that form factor. The braided sleeve and cloth-tape strain relief protect the connectors during installation.

Delivers sustained PCIe 3.0 four-lane throughput

Under continuous load the cable maintains a 12 Gb/s SAS link, letting the NVMe SSD operate at full PCIe 3.0 x4 bandwidth rather than throttling to SATA speeds. The 2.5 inch drive form factor benefits from the cable's heat-dissipation design during prolonged write-heavy workloads. Builders needing more than one U.2 device must add extra cards and cables, as this adapter handles a single drive only.

Questions about this item

What bandwidth limit does the SFF-8643 connector impose under sustained use?

The SFF-8643 link runs at 12 Gb/s, so sustained throughput is capped by that 12 Gb/s Mini SAS HD interface.

How much heat or power does the adapter cable itself add during all-day operation?

The passive cable assembly adds no active heat; only the NVMe SSD draws 3.3 V and 12 V from the integrated SATA power connector.

Which host-side card must already be installed for this cable to function?

A PCIe 3.0 x4 card with an SFF-8643 port — such as an ASRock U.2 add-in card or Gigabyte M.2-to-U.2 Mini SAS adapter — is required.
