Professional-grade USB4 cable

This 6.6 ft USB-C to USB-C cable delivers 80 Gbps bandwidth and 240 W power delivery under USB4 2.0 and Thunderbolt 5 compatibility. It targets creators and engineers who move large datasets and drive high-refresh-rate displays from a single connection. Buyers who need longer runs or active optical links will need a different solution.

Bandwidth and display headroom

The link handles 8K at 120 Hz or 4K at 480 Hz when the host and monitor support those modes, leaving headroom for multi-stream workflows. Data throughput caps at 80 Gbps, so the very fastest external RAID arrays may saturate the pipe. Legacy 40 Gbps hosts fall back to their native limit without extra configuration.

Thermals and power behaviour

The braided jacket and premium conductors keep the cable cool during sustained 240 W charging sessions. No active cooling is present, so the assembly remains silent while delivering Extended Power Range current. Backward compatibility with 140 W adapters ensures safe negotiation on older power sources.

Questions about this item

Will the 80Gbps cable work with my existing Thunderbolt 4 dock?

Yes, the cable is compatible with Thunderbolt 4 and USB standards, so it will function with your current dock at its supported speeds.

How can I verify the cable is delivering 240W charging and 8K@120Hz video?

Check your laptop and monitor settings to confirm they negotiate 240W USB PD 3.1 Extended Power Range and an 8K 120Hz or 4K 480Hz signal over DisplayPort Alternate Mode.

Does the 6.6ft cable include a power adapter or do I need to buy one separately?

The cable itself is the only item included; a USB PD 3.1 charger capable of 240W must be purchased separately to reach the maximum power rating.
