This Thunderbolt 5 cable connects USB-C devices at up to 80 Gbps and delivers up to 240 W of power. It suits creators, gamers and professionals who need fast data transfer and high-resolution video from a single 4.9 ft link.

Bandwidth headroom and display limits

The cable provides 80 Gbps bi-directional bandwidth and up to 120 Gbps with Bandwidth Boost for display traffic. It drives a single 16K at 60 Hz or 8K at 120 Hz screen, dual 8K or 6K at 60 Hz, or triple 4K at 144 Hz. Bandwidth runs out beyond those configurations.

Questions about this item

Will the 4.9 ft Thunderbolt 5 cable work with my existing USB 3.2 Gen 2x2 dock?

Yes, the cable is fully backward compatible with USB 3.2 Gen 2x2 and earlier USB standards, so your current dock will function normally.

How can I verify the cable is delivering the 80 Gbps bandwidth after connecting it?

Check your operating system's connection details or run a certified USB4 V2 bandwidth test; the link should report 80 Gbps bi-directional speed when both host and device support Thunderbolt 5.

Does the box include a 240 W charger or do I need to buy one separately?

The package contains only the USB-C to USB-C cable; a compatible 240 W charger must be purchased separately to reach the maximum power delivery rating.
