Delock SFF-8643 to U.2 Port Cable 75 cm

Delock SFF-8643 to U.2 Port Cable – 75 cm NVMe & SATA Power Link

The Delock SFF-8643 to U.2 cable connects SFF-8643 devices to U.2 (SFF-8639) ports, bridging the interface gap between PCIe add-in cards and U.2 storage drives. At 75 cm, it provides enough reach for typical internal PC layouts without excess cable clutter.

• SFF-8643 connector on one end and U.2 (SFF-8639) connector on the other — direct compatibility with NVMe and SATA drives in U.2 bays
• 75 cm cable length offers flexible routing inside desktop and server cases
• Single output (1×) ensures a dedicated, stable connection per drive
• Straight connector design (no angled plug) fits standard drive bays and PCIe brackets without clearance issues

What sets this cable apart

The Delock SFF-8643 to U.2 cable is a purpose-built link for internal NVMe and SATA storage in U.2 form-factor bays. Unlike generic adapters, it uses the correct SFF-8643 and SFF-8639 pinouts to ensure reliable data and power delivery without signal degradation.

Ideal for...

This cable suits users building or upgrading workstations and servers with U.2 NVMe or SATA drives. It is particularly useful when a PCIe card with an SFF-8643 output needs to connect to a U.2 drive bay — a common requirement in high-capacity storage setups.

Application of Delock SFF-8643 to U.2 Port Cable

1. Connect the SFF-8643 end to the PCIe card or HBA with an SFF-8643 output
2. Connect the U.2 (SFF-8639) end to the U.2 drive bay or U.2 NVMe/SATA drive
3. Route the 75 cm cable through the case to avoid strain on the connectors
4. Ensure the drive is powered and recognized by the system BIOS/UEFI
