USB4 80Gbps cable for high-speed workflows

This three-foot USB-C to USB-C cable delivers USB4 80Gbps data transfer and 240W Power Delivery 3.1 charging for laptops, docks and high-resolution displays. It suits creators and engineers who move large media files or drive multiple 4K and 8K monitors from a single port.

Simple plug-in with certified E-marker

The connectors carry laser-etched USB4 markings and certified E-marker firmware so the host negotiates 80Gbps and 240W automatically. No driver install is required, but the 30/34 AWG coaxial construction makes the cable stiffer than thinner leads, so tight bends behind desks need a little extra clearance.

Sustained throughput for long renders

Shielded coaxial wires maintain full 80Gbps bandwidth during extended file copies or multi-hour 8K 120Hz video streams without thermal throttling. Thunderbolt 4 compatible hosts keep the link stable under continuous load, while the 240W PD EPR contract holds steady voltage for power-hungry workstations.

Questions about this item

How can I confirm the cable is delivering 80Gbps after connecting it?

Check the host operating system or dock firmware for an active USB4 Gen 4 link and verify DisplayPort 2.1 Alt Mode is negotiating 8K at 120Hz or dual 4K at 120Hz, which only occurs at the rated speed.

What is included and what must be purchased separately?

The box contains the 3 ft USB-C male-to-male cable with laser-etched USB4 markings and a certified E-marker chip; any USB-C power adapter, dock, or display is sold separately.

Should I choose this 3 ft length or a longer version for a desktop monitor setup?

At 91 cm this cable suits close-range desktop connections; longer runs may need active cables to maintain 80Gbps and 240W PD 3.1 performance.
