CableCreation SFF-8643 to SFF-8639 Cable 1M

SKU CH-AB3C-KXF9S

Connects a PCIe SFF-8643 port to a U.2 NVMe SSD with integrated 15-pin SATA power over 1 metre

  • Connect PCIe SFF-8643 slots to U.2 NVMe SSDs via SFF-8639 interface
  • Achieve 12 Gb/s throughput with PCIe 3.0 four-lane NVMe connectivity
  • Power NVMe drives directly through integrated 15-pin SATA power connector
  • Compatible with ASRock, Gigabyte and ASUS Mini SAS HD add-in cards
  • RoHS certified for environmental compliance in servers and workstations

Mini SAS HD to U.2 NVMe Cable

This CableCreation cable links a PCIe expansion card with an SFF-8643 Mini SAS HD port to a U.2 NVMe solid-state drive. It includes an integrated 15-pin SATA power connector that draws 3.3V and 12V from the power supply to run the SSD. The 1 metre assembly suits servers, workstations and external storage arrays that lack a native U.2 header.

Sustained 12 Gb/s Four-Lane Throughput

The cable carries a PCIe 3.0 four-lane signal rated at 12 Gb/s per lane, so bandwidth scales with the drive rather than capping at SATA speeds. Shielded construction keeps signal integrity stable during long sequential reads and writes typical of database or video workloads. No active circuitry means latency stays at the cable level without thermal throttling.

Replaces SATA Cabling for NVMe Upgrades

Builders moving from 2.5-inch SATA SSDs to U.2 NVMe drives use this cable to bridge the interface gap without replacing the host card. The jump is worthwhile when the workload demands sustained throughput above the SATA 6 Gb/s ceiling. It does not serve systems that only have M.2 slots or lack an SFF-8643 connection.

Questions about this item

Does the SFF-8643 to SFF-8639 cable generate noticeable heat or draw extra power when running continuously?

The cable itself is passive and does not generate heat or draw power; only the connected U.2 NVMe SSD consumes 3.3V and 12V from the 15-pin SATA power connector.

What must my system already have for this 1-metre cable to work?

You need a controller or add-in card with an SFF-8643 Mini SAS HD port, a U.2 NVMe SSD with an SFF-8639 connector, and a free 15-pin SATA power lead from the power supply.

Will this cable work with an older PCIe 3.0 controller card and a current U.2 NVMe drive?

Yes, the cable carries a PCIe 3.0 four-lane link at 12 Gb/s per lane, so a PCIe 3.0 card and a modern U.2 NVMe SSD will operate together at full PCIe 3.0 speeds.
