40 Gbps USB-C cable for Thunderbolt 4 workflows

This 4 ft male-to-male cable delivers up to 40 Gbps data transfer, 240 W power delivery and 8K 60 Hz or dual 4K 60 Hz video. An integrated E-Marker chip ensures stable PD 3.1 charging and broad compatibility with Thunderbolt 4 and USB4 hosts.

Suits single-cable dock setups; not for longer runs

Professionals who need one cable for high-speed storage, dual-monitor chains and laptop charging will benefit. Builds that require lengths beyond 4 ft or ports other than USB-C must look elsewhere.

40 Gbps bandwidth is the deciding spec

If your host and peripheral both support 40 Gbps operation, this cable provides the full throughput for data, video and 240 W charging. Devices limited to lower speeds will not use the cable’s maximum capacity.

Questions about this item

How do I confirm the cable is delivering 40 Gbps after connecting it?

Check the host's Thunderbolt control panel or USB4 settings to see a 40 Gbps link speed and run a large file transfer to verify throughput.

What comes in the box and what must I buy separately?

The box contains the 4 ft USB-C to USB-C cable with E-Marker chip; you need a USB4 or Thunderbolt 4 host, a PD 3.1 charger up to 240 W, and an 8K-capable display to use every feature.

Which version or capacity should I choose for single 8K at 60 Hz versus dual 4K at 60 Hz?

This single 40 Gbps model supports one 8K 60 Hz or two 4K 60 Hz streams; pick the 80 Gbps version only if you need 16K or 8K 120 Hz.
