USB4 Cable 40Gbps 240W 8K

This USB4 cable delivers 40Gbps data transfer and up to 240W power delivery over a five-foot length. It supports 8K at 60Hz or dual 4K displays and is backward compatible with Thunderbolt 3 and USB 3.2, 3.1, 2.0 devices. The cable suits creators and professionals who need maximum bandwidth and charging from a single connection.

Who This Suits and Who Should Look Elsewhere

Ideal for users with Thunderbolt 4 or USB4 hosts who want full 40Gbps speed, 240W charging and 8K video. Not for buyers whose devices only support lower USB-C speeds or lack DisplayPort Alt Mode for video output. Also not for setups requiring longer cable runs beyond the supplied length.

The Deciding Specification

The single specification that decides fit is the 40Gbps data rate combined with 240W power delivery. If your host and peripheral both support USB4 or Thunderbolt 4 at that speed and power level, this cable will deliver the rated performance.
