Thunderbolt 5 cable for professional workflows

This 0.5m Thunderbolt 5 cable delivers 80Gbps bi-directional data transfer and 120Gbps video bandwidth for demanding creative tasks. It suits video editors, 3D artists and engineers who move large project files between certified host devices and high-resolution displays. The 240W power delivery charges high-performance laptops through the same connection.

Verify host port certification

Confirm your computer or dock provides a certified Thunderbolt 5 port to reach the stated 80Gbps data rate and 120Gbps video bandwidth. The cable also operates with Thunderbolt 4, Thunderbolt 3, USB4 and USB-C hosts at their native speeds. Match your monitor configuration to the supported modes: one 4K 540Hz, two 8K 60Hz or three 4K 144Hz displays.

Replaces slower active cables when bandwidth matters

This cable upgrades from older Thunderbolt or USB-C leads that limit file transfers to lower throughput or cannot drive multi-monitor arrays at high refresh rates. The jump is worth it when 80Gbps storage access, 240W charging and triple 4K 144Hz output are required simultaneously. It is not for users who only need basic USB-C charging or single 4K 60Hz video.

Questions about this item

Does the box include the ThunderLok-A locking clips or must they be purchased separately?

The cable ships with the ThunderLok-A compatible connectors already fitted; no additional clips are required for the lock to engage.

Why choose the 0.5 m length over a longer Thunderbolt 5 cable?

The half-metre length keeps the 80 Gbps bi-directional and 120 Gbps video bandwidth at full spec while minimising signal loss and desk clutter.

What does the 240 W rating mean when the cable is plugged into a laptop?

It can deliver up to 240 W of power over USB Power Delivery 3.1, enough to fast-charge high-performance laptops while simultaneously driving multiple 8K displays.
