USB4 40 Gbps cable for high-speed workflows

This 1.5 ft USB4 Gen 3x2 cable delivers up to 40 Gbps bi-directional data transfer and supports 240 W Extended Power Range charging. It connects laptops, docks, eGPU enclosures, phones and power banks with USB-C male-to-male reversible connectors. The cable handles single 8K at 60 Hz, 4K at 120 Hz or dual 4K at 60 Hz video when two cables are used.

Practical limits of USB4 Gen 3x2

Maximum throughput of 40 Gbps requires both host and device to implement USB4 Gen 3x2; older USB 3.2, USB 3.1 or USB 2.0 ports will fall back to their own lower speeds. Video output depends on the source supporting DisplayPort Alt Mode at the stated resolutions and refresh rates. Full 240 W power delivery needs a PD 3.1 EPR charger and a device capable of accepting 48 V at 5 A; otherwise the cable negotiates 180 W, 140 W, 100 W or lower profiles.

Installation notes and common issues

Plug the reversible USB-C ends into each port — no driver installation is required. Failures usually come from using a non-EPR charger when 240 W is expected, or from expecting 40 Gbps on a Thunderbolt 3 or USB 3.2 host. The short 1.5 ft length limits desk reach; verify device spacing before ordering. Damaged or dirty connectors can prevent high-speed negotiation or EPR handshake.
