  • Move 7 hours of HD video or 25,000 photos in one minute at 80Gbps
  • Works with Thunderbolt 3, 4 and 5 plus USB 2.0, 3.0, 3.2 Gen 1, Gen 2 and Gen 2x2

Thunderbolt 5 cable for high-bandwidth workflows

This 6.6 ft Thunderbolt 5 cable supports up to 80 Gbps data transfer and 240 W power delivery. It is built for professionals and creators who move large video files, drive multiple high-resolution displays, or charge power-hungry laptops through a single connection. Backward compatibility covers earlier Thunderbolt and USB standards.

80 Gbps bandwidth enables dual 8K

The cable’s 80 Gbps throughput allows a single 16K@60 Hz output, dual 8K@60 Hz monitors, or triple 4K@144 Hz displays. With Bandwidth Boost it can reach 120 Gbps for the most demanding display configurations. It also carries a 4K@540 Hz signal for high-refresh gaming or precision editing work.

Check your host port and charger before ordering

Full 80 Gbps speed and 240 W charging require a Thunderbolt 5 or USB4 Gen 4 port plus a 48 V/5 A charger. On Thunderbolt 3, Thunderbolt 4, or USB 3.2 ports the cable will fall back to 20 Gbps or 40 Gbps bandwidth. Without a high-wattage supply the maximum power delivered will be lower.

Questions about this item

Will the 240W charging capability degrade over time?

The cable is built to the USB4 V2 standard with 48V/5A power delivery, so the 240W rating is maintained for the life of the cable.

What limits the 80Gbps data rate during long transfers?

Sustained 80Gbps throughput requires a Gen4 port; on Gen3 ports the ceiling is 40Gbps and on Gen2 ports it is 20Gbps.

Does the cable get warm when delivering 240W continuously?

The cable is rated for 240W (48V/5A) operation and is designed to handle that load without overheating.
