LORDWORLD U.2 SFF-8639 NVME PCIe 3.0 x4 Cable 50cm

SKU CH-W2C4-9RBJ2

Connects U.2 NVMe SSDs to SFF-8643 Mini SAS HD controllers at PCIe 3.0 x4 speeds over a 50 cm cable

  • Connect Intel SSD 750 at PCIe 3.0 x4 speed
  • 50 cm cable fits compact chassis without signal loss
  • SFF-8639 U.2 connector links M.2 SFF-8643 Mini SAS HD drives
  • 4 GBps throughput supports high-performance storage controllers
  • Cable-only design lets you choose your own adapter card

U.2 NVMe PCIe 3.0 x4 Cable 50cm

This 50 cm cable connects a U.2 NVMe SSD to a motherboard or controller using an SFF-8639 connector. It carries a PCIe 3.0 x4 link rated at 4 GBps. The cable is sold alone without an adapter or card. It is intended for system builders adding U.2 storage.

Suits builders with U.2 bays and SFF-8643 headers

This cable fits installations where the board provides an SFF-8643 Mini SAS HD port for U.2 drives. It does not suit systems lacking that specific header or builds needing a longer reach than 50 cm. Buyers who need an included adapter card or a different connector type should look elsewhere.

PCIe 3.0 x4 at 4 GBps over SFF-8639

The cable delivers a PCIe 3.0 x4 connection rated at 4 GBps through the SFF-8639 interface. This bandwidth figure determines whether the link can saturate the attached NVMe drive. Verify that the host controller and drive both support this generation and width.

Questions about this item

How can I confirm the 50cm cable is delivering PCIe 3.0 x4 speeds after connecting my Intel SSD 750?

The system should detect the drive at full PCIe 3.0 x4 width in BIOS or Device Manager, and benchmark tools will show sequential throughput approaching 4 GBps when the native NVM Express driver is active.

The listing says cable only — what else do I need to buy to use this with an SFF-8643 Mini SAS HD controller?

You must supply the SFF-8643 to SFF-8639 adapter or a compatible Ultra M.2 add-in card; the 50cm cable connects the U.2 drive to that adapter or card.

Should I choose this 50cm length for a standard ATX build or is a different length better?

At 50cm it reaches from a typical motherboard U.2 port or rear-mounted adapter to a 2.5" drive bay in most ATX cases; measure your specific routing before deciding.
