  • 5 m length keeps signals stable across the desk
  • Works with MacBook M2 M3 Windows docks and NVMe drives

Cable specification and intended use

This 1.5 metre USB-C to USB-C cable meets Thunderbolt 5 and USB4 Generation 4 specifications. It is built for professionals moving large media libraries between a laptop and an external NVMe SSD, and for power users charging high-performance workstations through a single connector.

Bandwidth and power limits

The 80Gbps data ceiling is set by the Thunderbolt 5 and USB4 Gen4 standards the cable implements; actual throughput depends on the host controller and the storage device attached. The 240W Power Delivery maximum requires a charger and a device that both negotiate that level; lower-rated hardware will fall back to their own limits.

Capacity and headroom

The link comfortably drives a 16K display at 60Hz or a 4K panel at 120Hz with HDR, leaving headroom for simultaneous data traffic to an external drive. It will not support resolutions or refresh rates beyond those two modes, and the 1.5m length is fixed; longer runs would need an active or optical alternative.

Questions about this item

Should I pick this 1.5m cable or a shorter length for my desk setup?

The 1.5m length is designed to balance tidy desktop wiring with operational flexibility, maintaining stable 80Gbps signal integrity without speed attenuation.

What does the 80Gbps rating actually deliver when I plug in an external NVMe SSD?

It enables ultra-fast transfer of large 4K or 8K video files and massive backups, drastically cutting wait times compared to slower cables.

Does the Thunderbolt 5 interface cap the 240W charging or 16K@60Hz video in any way?

The cable fully conforms to Thunderbolt 5 and USB4 Gen4 specs, simultaneously supporting 240W power delivery, 80Gbps data, and 16K@60Hz or 4K@120Hz HDR video output.
