40Gbps USB4 Cable for Video and Power

This 6.6ft cable carries up to 40Gbps of data and supports 8K video at 60Hz or 4K at 240Hz through DP Alt Mode. It delivers up to 240W of power via USB PD 3.1 Extended Power Range. The cable works with USB4 devices and Thunderbolt 4 hosts.

Bandwidth and Protocol Limits

Maximum throughput is 40Gbps on USB4 gear and the cable falls back to 20Gbps on 20Gbps USB4 hardware. Older USB 3.2, 3.1, 3.0 and 2.0 devices connect at their native speeds. Video output requires a host and display that both implement DP Alt Mode.

Build and Daily Use

The black USB-C to USB-C construction handles 28V/140W, 36V/180W and 48V/240W profiles without a separate power brick. Length suits desk-to-monitor or laptop-to-dock runs while keeping the connector strain low. Buyers who need longer reach or angled plugs will need a different cable.
