Micro Connectors 12G U.2 Cable SFF-8643 to SFF-8639 with SATA Power 50cm

SKU CH-69F3-E6REX

Connects a 36-pin SFF-8643 controller to a 68-pin SFF-8639 NVMe SSD with integrated 15-pin SATA power over 50cm

  • ColorBlack & Light Blue
  • Enables NVMe SSD performance via 12G U.2 PCIe 3.0 four-lane connection
  • Connects HD Mini-SAS SFF-8643 to U.2 SFF-8639 with integrated 15-pin SATA power
  • Supports 2.5-inch NVMe U.2 drives such as Intel 750 series SSDs
  • Flexible braided 50cm cable with 36-pin and 68-pin male connectors for internal routing
  • RoHS compliant construction ensures restricted-substance compliance for system builds

U.2 NVMe Cable for RAID Cards

This internal cable connects a PCIe add-in card with an SFF-8643 port to a 2.5-inch U.2 NVMe SSD using the SFF-8639 interface. It supplies drive power through an integrated 15-pin SATA receptacle drawing 3.3V and 12V from the PSU. The 50cm length suits typical chassis routing. It targets builders adding high-speed NVMe storage to systems lacking native U.2 headers.

Straightforward Install With Latch

The 36-pin SFF-8643 male connector features a latch that secures it to the RAID or HBA card. The 68-pin SFF-8639 male end plugs directly into the SSD U.2 port. A separate SATA power lead must reach the PSU; forgetting this connection leaves the drive unpowered. The braided sleeve adds stiffness, so allow slack when routing behind motherboards or drive cages.

Sustained 12G Four-Lane Throughput

The cable carries a PCIe 3.0 four-lane link rated at 12G per lane, maintaining full bandwidth during extended heavy I/O such as RAID rebuilds or video ingest. No active components mean no thermal throttling. Signal integrity depends on secure latching and avoiding sharp bends. It does not support drives requiring a second power rail beyond the SATA connector.

Questions about this item

How can I confirm the 12G U.2 cable is working after connecting the SFF-8643 and SFF-8639 ends?

The system should detect the NVMe SSD in BIOS or the OS device manager once the 36-pin SFF-8643 male and 68-pin SFF-8639 male connectors are seated and the 15-pin SATA power receptacle is plugged in.

What connectors and cables are included with the Micro Connectors 12G U.2 Cable?

The box contains the 50cm braided cable with a 36-pin HD Mini-SAS SFF-8643 male latch connector on one end, a 68-pin U.2 SFF-8639 male connector on the other, and an integrated 15-pin SATA power receptacle.

Which version of this cable suits an Intel 750 series 2.5-inch SSD?

This SFF-8643 to SFF-8639 cable with SATA power is built for that Intel 750 series 2.5" SSD and other NVMe U.2 drives using a 68-pin U.2 port.
