U.2 SFF-8639 NVMe Cables & Adapter Cards

Connect PCIe 4.0/5.0 servers, storage platforms and validation systems to U.2 SFF-8639 NVMe SSDs. Match the host interface, lane count, power and cable length before requesting a quote.

Host Interfaces

MCIO, SlimSAS, M.2, PCIe slot and U.2 paths.

PCIe Generations

PCIe 4.0 and PCIe 5.0 models for NVMe projects.

Quote Matching

Share lane count, power, length, quantity and platform.

U.2 SFF-8639 Model Selection

U.2 projects require more than a connector match. Confirm the host interface, PCIe generation, lane count, SFF-8639 device side, 15-pin power path, cable length and chassis clearance.
