PCIe 3.0 x4 Male to x1 Female Up R/A Extension Cable

The PCIe 3.0 x4 Male to x1 Female Up R/A Extension Cable is a specialized passive adapter solution designed for space-constrained systems requiring both form-factor adaptation and optimized cable routing. This cable converts a PCIe x4 slot interface to a PCIe x1 interface while incorporating an Up Right-Angle (Up R/A) female connector to facilitate vertical clearance and efficient cable management. Engineered for PCIe 3.0 compliance, it supports data rates up to 8.0 GT/s per lane, enabling a bandwidth of ~985 MB/s for the x1 end while maintaining mechanical compatibility with x4 host slots. Constructed with low-loss cables and multi-layer EMI shielding, this adapter is ideal for high-density servers, test benches, and embedded systems where physical space limitations demand compact, right-angle connections.

Features

• Form Factor Adaptation with Right-Angle Design: Converts a PCIe x4 male edge connector to a PCIe x1 female Up R/A receptacle, allowing x1 devices to be installed in x4 slots while minimizing vertical profile for improved clearance in cramped enclosures.
• PCIe 3.0 Compliance: Supports PCIe 3.0 specifications at 8.0 GT/s per lane, with backward compatibility to PCIe 2.0/1.0, ensuring reliable signal integrity for x1 devices operating in x4 slots.
• Up Right-Angle Connector Optimization: The Up R/A female connector directs the cable upward relative to the motherboard plane, simplifying routing around adjacent components and reducing mechanical stress in densely packed systems.
• Enhanced Shielding: Utilizes foil and braid shielding layers to minimize crosstalk and EMI, critical for maintaining signal stability at high speeds in electrically noisy environments.
• Passive Operation: Requires no external power or active components, leveraging precision impedance-controlled wiring (85-ohm differential) for passive signal extension.
• Durable Construction: Features gold-plated contacts (?0.76µm) and reinforced housing to withstand repeated mating cycles in development or industrial environments.
