Thunderbolt 5 cable for high-speed workflows

This Thunderbolt 5 cable delivers up to 80 Gbps bandwidth and 240 W power delivery over a 4.9 ft length. It suits professionals who move large media libraries, drive 16K displays or charge high-wattage laptops through a single Type-C connection.

Check your host port generation before ordering

The cable reaches 80 Gbps only with Gen4 ports; Gen3 ports cap at 40 Gbps and Gen2 ports at 20 Gbps. Video output up to 16K at 60 Hz or dual 8K also requires a host controller that supports those modes. Power delivery of 240 W needs a compatible charger and device negotiation at 48 V and 5 A.

Sustained throughput stays at the negotiated

During long transfers the link remains at the speed class of the connected port — 20, 40 or 80 Gbps — without thermal throttling noted in the data. The 240 W charging hold is maintained continuously when both ends support the full power profile.

Questions about this item

Does the 4.9 ft Thunderbolt 5 cable include a power adapter, or must I buy one separately to reach 240 W charging?

The cable alone supports up to 240 W at 48 V/5 A. A compatible 240 W charger is required and is not included in the box.

The specs list 80 Gbps, 40 Gbps and 20 Gbps — how do I know which speed my Thunderbolt 5 port will deliver?

The cable reaches 80 Gbps with Gen4 ports, 40 Gbps with Gen3 and 20 Gbps with Gen2. Check your device’s port generation to match the expected bandwidth.

What does the 80 Gbps figure mean when I connect an external SSD and a 16K display at the same time?

The 80 Gbps total bandwidth is shared. A single 16K@60 Hz stream or dual 8K output uses most of it, so SSD transfers will run at the remaining throughput.
