One Cable for Data Video Power

This USB4 cable carries up to 40 Gbps of bandwidth, supports 8K video output, and delivers up to 240 W of charging power. It works with Thunderbolt 3 and Thunderbolt 4 hosts and devices, and remains backward compatible with USB 3.2, USB 3.1 and USB 2.0 equipment. The five-foot length suits desktop and docking setups.

Fits USB-C Ports with Alt Mode

Plug the cable into any USB-C port that supports DisplayPort Alternate Mode to drive one 8K@60 Hz or 5K@60 Hz display, or two 4K@60 Hz monitors simultaneously. It also connects high-speed storage, docking stations and peripherals without needing separate power bricks. No legacy video connectors are supported.

Sustained 40 Gbps and 240 W Delivery

The cable maintains full 40 Gbps throughput and 240 W power delivery under continuous load thanks to USB PD 3.1 Extended Power Range at 28 V, 36 V and 48 V steps. It handles prolonged 8K video streaming and large-file transfers without throttling. Ports limited to 20 Gbps or lower wattage will operate at their own maximums.

Questions about this item

Will the 40 Gbps bandwidth hold steady during long file transfers?

The cable is rated for up to 40 Gbps on USB4 devices and remains backward compatible with 20 Gbps USB4 gear, so sustained throughput depends on the connected host and storage speeds.

Does the cable get hot or draw extra power when running 240 W charging all day?

It supports USB PD 3.1 Extended Power Range at 28 V/140 W, 36 V/180 W and 48 V/240 W with no active cooling required; heat will follow the charger and device limits rather than the cable itself.

What must my laptop or monitor already have for 8K video to work over this cable?

The host USB-C port must support DisplayPort Alternate Mode; without Alt Mode the cable cannot carry an 8K@60 Hz or dual 4K@60 Hz signal.
