USB4 cable for high-bandwidth workflows

This 6.6ft USB4 cable delivers up to 40Gbps bandwidth, 8K@60Hz or 4K@240Hz video, and 240W PD 3.1 charging. It suits creators and professionals who move large files between USB4 hosts, docks, and monitors while powering demanding laptops from a single connection.

Sustained 40Gbps throughput with PD 3.1 EPR

The cable maintains 40Gbps data rates during extended transfers and supports PD 3.1 Extended Power Range profiles at 28V/140W, 36V/180W, and 48V/240W. Backward compatibility covers 20Gbps USB4, USB 3.2, USB 3.1, USB 3.0, and USB 2.0 devices without speed negotiation issues.

Check host port capabilities before ordering

Verify that your USB-C port implements USB4 or Thunderbolt 4 with DP Alt Mode for 8K video and PD 3.1 for 240W charging. Ports limited to USB 3.2, USB 3.1, or USB 2.0 will restrict bandwidth, video resolution, and maximum power delivery to their native specifications.

Questions about this item

Does the 240W charging capability generate noticeable heat during extended use?

The cable supports USB PD 3.1 Extended Power Range at 48V/240W, 36V/180W and 28V/140W for high-power delivery without specifying thermal behaviour.

Which ports must my devices already have to use the 40Gbps data rate and 8K video?

Both ends need USB-C ports that implement USB4 or Thunderbolt 4 with DisplayPort Alt Mode to reach 40Gbps bandwidth and 8K@60Hz video.

Will the cable still deliver 4K@240Hz video when connected to a USB 3.2 Gen 2 port?

The cable is backward compatible with USB 3.2, 3.1, 3.0 and 2.0, but 4K@240Hz and 8K@60Hz require DP Alt Mode on a USB4 or Thunderbolt 4 host.
