3 m Thunderbolt 4 cable for 240 W charging

This three-metre USB-C cable carries Thunderbolt 4 signalling and USB4 data at 40 Gbps. It delivers up to 240 W of power under the PD 3.1 specification at 48 V and 5 A. The length suits desktop setups where the host and peripheral sit farther apart.

Plug-and-play with backward compatibility

The cable works immediately with any USB-C port that supports Thunderbolt 3 or Thunderbolt 4. It also falls back to USB 3.2, 3.1, 3.0 and 2.0 speeds when connected to older hosts. No driver installation is required, but the host must explicitly support Thunderbolt or USB4 to reach the rated throughput.

8K 60 Hz or dual 4K 60 Hz display headroom

A single 8K monitor at 60 Hz or two 4K monitors at 60 Hz can be driven over the link. Bandwidth is sufficient for high-speed SSD enclosures and eGPU docks that use Thunderbolt 4. The cable cannot exceed 40 Gbps, so devices needing higher aggregate display bandwidth will be limited.

Questions about this item

How do I confirm the cable is delivering 240 W charging after setup?

Connect a PD3.1-capable charger and device, then check the power readout on the charger or device software to verify it reaches 48 V/5 A.

What comes in the box and what must I buy separately?

The package contains the 3 m USB-C to USB-C cable only; you need a PD3.1 charger and compatible host or monitor for full 240 W, 40 Gbps or 8K@60 Hz operation.

Which version should I choose for 8K@60 Hz or dual 4K@60 Hz monitors?

This single 3 m cable supports both 8K@60 Hz and dual 4K@60 Hz over Thunderbolt 3/4 and USB4 hosts, so no alternative version is required for those modes.
