Cable Overview

The SMUGDESK USB 4 cable delivers up to 40 Gbps data transfer and 100W Power Delivery 3.1 charging over a 6.6FT length. It supports Thunderbolt 4 and 3 hosts, enabling fast links to NVMe SSD enclosures, eGPU docks, and high-resolution monitors for demanding creative or gaming setups.

Practical Limits

Maximum video bandwidth allows one 8K, 5K or 6K display at 60Hz, or dual 4K monitors at 60Hz, with a single 4K panel reaching 144Hz. Data throughput hits 40 Gbps only when both host and device support the full Thunderbolt 4 or USB4 specification; otherwise speeds fall back to the lowest common standard.

Installation Notes

Connect the USB-C plugs directly to host and peripheral; no driver installation is required for Thunderbolt 4 or USB4 hosts. The 6.6FT reach suits desktop routing but adds signal attenuation risk, so keep the path clear of tight bends. Charging at 100W demands a PD 3.1 EPR source and a device that accepts 20V/5A; lesser chargers or cables will negotiate lower power.

Questions about this item

Which length should I choose for my desk setup?

The 6.6 ft cable reaches across most workstations; the 1.6 ft version suits tight docking stations or travel bags.

What does the 40 Gbps rating deliver with an NVMe enclosure?

It lets an NVMe SSD run at its full PCIe 3.0 x4 potential, so large project files transfer in seconds instead of minutes.

How does the Thunderbolt 4 interface limit charging and video?

The cable carries 100 W PD 3.1 power and drives one 8K 60 Hz or dual 4K 60 Hz displays simultaneously.
