USB4 40 Gbps Cable for Thunderbolt 3/4

This 3.3 ft USB4 cable carries 40 Gbps data and 240 W power over USB‑C to USB‑C male connectors. It supports single 8K at 60 Hz or dual 4K at 60 Hz video when the host and display allow. Aluminium alloy and braided nylon construction is designed for daily desk or travel use.

Who This Suits and Who Should Look Elsewhere

Buyers needing full Thunderbolt 3 or 4 bandwidth for docks, eGPUs or high‑speed storage will match the 40 Gbps rating. Builders who require longer runs, active optical lengths or legacy USB‑A connectors cannot use this cable.

40 Gbps Decides Fit

The 40 Gbps USB4 specification determines whether the link saturates Thunderbolt 3/4 devices or falls back to slower USB 3.2, 3.1 or 2.0 speeds. Confirm the host port and peripheral both advertise 40 Gbps before purchasing.

Questions about this item

What USB-C power source is needed to reach the 240W charging rate?

A USB-C charger or host that delivers 48V at 5A using the PD3.1 fast-charging protocol will provide the full 240W.

Will this cable work with a Thunderbolt 3 dock I already own?

Yes, the cable is backwards compatible with Thunderbolt 3 and will carry 40Gbps data and video through a Thunderbolt 3 dock.

How can I confirm the cable is running at 40Gbps after connecting it?

Check the host system's connection details; it should report a 40Gbps link when both the source and destination devices support USB4 or Thunderbolt 4 speeds.
