Cable Overview

This SMUGDESK USB4 cable measures 1.5FT and delivers up to 240W of power at 48V/5A. It supports data transfer speeds of 40Gbps and video output up to 8K at 60Hz. The cable is compatible with Thunderbolt 4 and backwards compatible with Thunderbolt 3, USB 3.2, USB 3.1, and USB 3.0 devices.

Suitability

This cable suits users who need maximum charging power and high bandwidth for external SSDs, eGPUs, or docking stations. It is not for buyers who require a longer cable run for distant peripherals. It is also not for setups where the host or device does not support USB4 or Thunderbolt 4 to utilise the full 40Gbps speed.

Deciding Spec

The single specification that decides fit is the 40Gbps data rate combined with 240W power delivery. If your hardware supports this bandwidth and wattage, the cable will perform at its rated ceiling. If your devices only support lower USB standards, the extra headroom will not be used.

Questions about this item

What USB-C power source do I need to get the 240W charging rate?

A USB-C charger or host port rated for 48V/5A (240W) is required; the cable itself supports up to that level.

Will this cable run at 40Gbps with my Thunderbolt 3 dock?

It is backward compatible with Thunderbolt 3, but the link will negotiate to Thunderbolt 3 speeds rather than the full 40Gbps.

How can I confirm the cable is delivering 8K at 60Hz after I plug it in?

Check the display settings on your host — they should show 8K resolution at 60Hz if the source and monitor both support that mode.
