USB4 cable with 40Gbps bandwidth

This USB4 cable delivers up to 40Gbps data bandwidth and supports 240W power delivery at 48V5A. It handles 8K video at 60Hz or dual 4K at 60Hz for display connections. The 3.3ft length suits desk setups linking laptops, monitors, SSDs and phones. Compatible with Thunderbolt 3 and 4 hosts.

Sustained 40Gbps throughput for long transfers

At the full 40Gbps Gen3 rate the cable can move roughly 14 hours of HD video or 25000 HD photos in about one minute. Performance scales to the port generation used; Gen2 ports limit bandwidth to 20Gbps. The 240W PD 3.1 charging holds steady during extended sessions when both charger and device support the standard. Thermal design keeps the connection stable under continuous load.

USB4 and Thunderbolt 3/4 interface limits

The cable reaches its 40Gbps ceiling only on USB4 Gen3 or Thunderbolt 3 and 4 ports; older USB 3.2 Gen2 ports cap at 20Gbps. Video output requires host support for DisplayPort Alt Mode at 8K60 or dual 4K60. Maximum 240W charging needs a PD 3.1 source and sink; QC 4.0 devices negotiate lower power. Cable length is fixed at 3.3ft, so longer runs need an active solution.

The cable supports up to 240W at 48V/5A with a compatible charger; heat depends on the charger and device, not the cable itself.

What charger and port do I need to reach the 40Gbps data rate?

You need a USB4 Gen3 port and a PD 3.1 charger capable of 240W; Gen2 ports limit bandwidth to 20Gbps.

Will this cable drive an 8K@60Hz monitor from a Thunderbolt 3 laptop?

Yes, it supports single 8K@60Hz or dual 4K@60Hz video over Thunderbolt 3 or 4 connections.
