M.2 NVMe Male Right Bend to PCIe 4.0 x4 Female Down R/A Extension Cable, 85-ohm Low Impedance

The M.2 NVMe Male Right Bend to PCIe 4.0 x4 Female Down R/A Extension Cable is a specialized interface conversion solution engineered to connect M.2 NVMe slots to standard PCIe 4.0 x4 interfaces with a right-angled cable orientation, downward right-angle connector design, and precision 85-ohm impedance control. This cable enables the use of M.2 NVMe storage and other M.2 PCIe devices with motherboard PCIe x4 slots, providing flexible expansion capabilities for systems where direct M.2 slot availability is limited or where specific right-bend downward cable routing is required for space-optimized configurations. Supporting PCIe 4.0 specifications, it delivers a data transfer rate of up to 16 GT/s per lane while maintaining backward compatibility with PCIe 3.0 and 2.0 devices. The unique combination of right-bend cable design and downward right-angle (Down R/A) female connector directs the cable both rightward and downward from the motherboard plane, optimizing space utilization and improving clearance in complex chassis layouts and custom mounting scenarios, particularly beneficial in low-profile environments like 1U server racks or compact embedded systems. Constructed with 85-ohm impedance-controlled wiring and multi-layer shielding, this cable ensures reliable signal integrity and minimizes electromagnetic interference at high frequencies. Its flexible flat cable design allows for easy routing in space-constrained environments, making it ideal for custom builds, embedded systems, and expansion projects where traditional adapter cards cannot be used and combined right-bend downward cable orientation is essential for optimal chassis layout and thermal management.
