Thunderbolt 4 cable for high-speed workflows

This Cable Matters cable delivers 40Gbps throughput under the Thunderbolt 4 standard. It suits creators and professionals who move large project files between workstations, RAID arrays or high-resolution cameras. The 3.3ft length keeps a tidy desk while reaching docks or monitors placed close to the host.

Check host port and power needs

Verify that your computer or dock provides a Thunderbolt 4 or USB4 port with full 40Gbps capability; some USB-C ports only run at lower speeds. Confirm the connected device can accept up to 240W of USB PD 3.1 power if you plan to charge a laptop through the same cable. DisplayPort Alt Mode must be supported on both ends for 8K or dual 4K video output.

Ideal for single-cable docks.

Buyers who want one cable for 40Gbps data, 8K video and 240W charging on Thunderbolt 4 or USB4 hosts will benefit. Builders whose systems only offer USB 3.2 or Thunderbolt 3 without full feature parity should look at something else, as they cannot use the maximum bandwidth, power delivery or display modes this cable enables.

Questions about this item

What comes in the box and do I need to buy any adapters separately?

The package contains the Thunderbolt 4 cable only; no extra adapters are required because it works directly with Thunderbolt 3, USB4 and USB-C ports.

Which version should I choose for 8K video and 240W charging?

This single 3.3ft model already supports 40Gbps bandwidth, 8K display output and PD 3.1 240W charging, so no other version is needed.

What does the 40Gbps rating mean when I connect it to my laptop and monitor?

It delivers up to 40Gbps of data throughput, enough to drive one 8K display or two 4K displays while simultaneously providing up to 240W of power.
