One cable for data, video and power
This USB4 cable carries up to 40 Gbps bandwidth, 8K video via DisplayPort Alt Mode and USB Power Delivery 3.1 Extended Power Range up to 240 W. It suits anyone who wants a single connection between a laptop, dock, monitor or high-speed NVMe enclosure without swapping leads.
Plug it in and it works
Both ends are USB-C so orientation never matters; the cable is backward compatible with USB 3.2, USB 2.0 and Thunderbolt 3 or 4 hosts. The only common issue is using a port or charger that does not support the required USB4 or PD 3.1 EPR profile, which caps speed or power to the lower standard.
Limits of the USB4 interface
Bandwidth tops out at 40 Gbps, so the very fastest PCIe storage or dual 8K streams cannot be saturated. PD 3.1 EPR negotiates 28 V, 36 V or 48 V up to 240 W, but the host and charger must both implement the same voltage step; otherwise charging falls back to 140 W or less. DisplayPort Alt Mode allows one 8K 60 Hz or two 4K 60 Hz displays, not higher refresh rates at those resolutions.

Questions about this item
How do I confirm the cable is delivering 40Gbps after connecting my NVMe enclosure?
Check the operating system device information or enclosure utility for a 40Gbps link speed and run a large file transfer to verify throughput matches the rated bandwidth.
What is included in the box and what must be purchased separately?
The box contains the USB4 USB-C to USB-C cable at 3.3FT length; a compatible 240W power adapter and NVMe enclosure or monitor must be purchased separately.
Which version should I choose for dual 4K@60Hz monitors versus a single 8K@60Hz display?
This single cable supports both configurations — one 8K@60Hz display or dual 4K@60Hz displays — so no alternate version is required.
