BUCIER Internal 12G HD Mini SAS SFF-8643 to U.2 SFF-8639 NVMe PCIe SSD Adapter Cable with SATA Power 0.5m

SKU CH-RV2S-GHB5K

Connects a U.2 NVMe SSD to a Mini SAS SFF-8643 host with integrated SATA power over a 0.5m cable

Cable Length 0.5m

  • Connect NVMe U.2 SSDs via 12G Mini SAS SFF-8643
  • 5 m cable with integrated SATA power for 3.3 V and 12 V supply
  • Supports Intel SSD 750 P3600 P3700 U.2 drives
  • Braided sleeve with cloth-tape strain relief on both connectors
  • Compatible with 2-port Mini SAS HD add-in cards

Target Build Scenario

This adapter cable connects a U.2 NVMe SSD to a Mini SAS HD SFF-8643 port on a RAID or storage add-in card. It suits builders adding high-speed storage to a workstation or server that lacks a native U.2 connector on the motherboard. The 0.5 metre length fits compact chassis routing.

Decisive Connector Match

The cable carries a 12G HD Mini SAS SFF-8643 plug on one end and a U.2 SFF-8639 receptacle on the other. It supports a PCIe 3.0 four-lane link to compatible drives such as the Intel SSD 750, P3600 and P3700 series. An M.2 SSD cannot attach directly without a separate M.2 to U.2 adapter.

Sustained Operation Behaviour

Integrated SATA power delivers 3.3V and 12V rails from the power supply to the SSD, avoiding reliance on the card slot for current. A braided sleeve and cloth-tape strain relief protect the conductors during continuous data transfer. The assembly is built for 2.5 inch form-factor drives mounted in a fixed position.

Highlights

  • Connect NVMe U.2 SSDs via 12G Mini SAS SFF-8643
  • 5 m cable with integrated SATA power for 3.3 V and 12 V supply
  • Supports Intel SSD 750 P3600 P3700 U.2 drives
  • Braided sleeve with cloth-tape strain relief on both connectors

Questions about this item

What does the 12G rating mean for my NVMe SSD?

The 12G rating refers to the Mini SAS HD SFF-8643 link speed. Your NVMe SSD will run at PCIe 3.0 four-lane speeds through this adapter, not at 12 Gbps.

Does the SFF-8643 connector limit the drive to SAS speeds?

No. The SFF-8643 end plugs into a PCIe add-in card, so the U.2 SSD uses a PCIe 3.0 four-lane connection. The SAS connector is only the physical interface.

What clearance does the 0.5m cable and SATA power plug need?

The cable is 0.5m long with a braided sleeve. You need room for the SFF-8639 U.2 connector at the drive, the SFF-8643 plug at the card, and a standard SATA power lead from your PSU.
