USB4 Cable 240W 40Gbps 8K 4ft Grey

This USB4 cable connects Thunderbolt 3 and Thunderbolt 4 hosts with USB-C peripherals. It supports up to 40Gbps data transfer and 240W power delivery for charging laptops, phones and accessories. The cable also drives a single 8K or 5K display at 60Hz or dual 4K displays at 60Hz. It is suited for professionals who need high-speed storage, docking stations and multi-monitor setups.

Installation and common issues

The cable uses male-to-male USB-C connectors and works plug-and-play with compatible hosts. For video output the host USB-C port must support DisplayPort Alternate Mode; otherwise no signal will appear. Data speed depends on the host controller and attached device, so actual throughput may be lower than the 40Gbps maximum. Charging at 240W requires a charger and device that both support 48V/5A USB Power Delivery.

What to check before ordering

Verify that your computer or dock has a USB-C port with DisplayPort Alternate Mode if you plan to drive a monitor. Confirm that your charger and device support 240W USB Power Delivery to reach the maximum charging rate. Ensure the connected storage or peripheral can operate at the desired speed, as the cable is backward compatible with USB 3.2, 3.1 and 2.0 but will run at the lowest common rate.

Questions about this item

How can I verify the cable is delivering 40 Gbps after connecting it?

Check the host device's transfer-rate indicator or run a large-file copy; the cable supports up to 40 Gbps and real-world reads of 2.8 GB/s and writes of 2.1 GB/s when both ends and the drive support that speed.

What comes with the cable and what must I provide separately?

The package contains the 4 ft USB-C to USB-C cable only; you must supply a 240 W-capable charger and devices with USB-C ports that support DisplayPort Alternate Mode for video.

Which version of this cable should I choose for 8K 60 Hz or dual 4K 60 Hz?

This single model handles one 8K 60 Hz or 5K 60 Hz display, or two 4K 60 Hz displays using two cables, provided the host supports DisplayPort Alternate Mode.
