USB4 cable for 8K displays and high-power charging

This USB4 cable connects USB-C devices such as laptops, tablets and monitors. It carries video up to 8K at 60 Hz, data at 40 Gbps and power up to 240 W. The four-foot length suits desktop and portable setups.

Bandwidth and power limits of the USB4 interface

The cable supports 40 Gbps data throughput, yet actual speed depends on the host controller and storage device. Video output reaches 8K at 60 Hz or dual 4K displays when two cables are used. Power delivery tops out at 48 V and 5 A, so the charger and device must both support 240 W for maximum charging rate.

Plug-in installation with common compatibility

Both ends are male USB-C connectors, so installation is a simple plug-in. The cable works with Thunderbolt 3 and 4 hosts and is backward compatible with USB 3.2, 3.1 and 3.0 ports. Performance drops if either the source or the display does not support the required USB4 or Thunderbolt specification, and 240 W charging only occurs when the power supply and device negotiate that level.

Questions about this item

Which length should I pick for a desk setup?

The cable is offered in a single 4FT length, suitable for typical desk-to-monitor distances.

What does the 40Gbps figure mean when I copy large files?

Theoretical peak is 40Gbps; real-world reads reach about 2.8GB/s and writes about 2.1GB/s if both host and storage support that speed.

How does the Thunderbolt interface affect charging limits?

Thunderbolt 3 and 4 compatibility lets the cable deliver up to 240W (48V/5A) when the charger and device both support USB Power Delivery at that level.
