USB 4.0 cable for high-speed workflows

This USB 4.0 cable connects two USB‑C devices at up to 40Gbps and delivers up to 240W of power. It suits professionals moving large files between NVMe enclosures, eGPUs, docking stations or high‑capacity SSDs. The 3.3FT length keeps desktop setups tidy while supporting 8K video output.

Build integration and cable replacement

The cable uses USB‑C male connectors on both ends and works bidirectionally with laptops, tablets, phones, hubs and power banks. It replaces older USB 2.0, 3.0, 3.1, 3.2 and Thunderbolt 3 or 4 cables, reducing the number of leads a workstation needs. Dual 4K monitor support requires two cables.

Thermals, noise and power behaviour

Passive construction means no fans and silent operation under any load. The PD 3.1 Extended Power Range handles 48V at 240W, with backward compatibility down to 60W, so the cable runs cool during sustained 140W or 180W charging sessions.

Questions about this item

Does the 40 Gbps data rate hold steady when the cable is also delivering 240 W to a laptop?

The cable supports up to 40 Gbps and 240 W simultaneously; sustained throughput depends on the host and device controllers, not the cable itself.

How warm does the cable get when running 240 W PD 3.1 EPR all day?

The nylon braid and integrated E-Marker are rated for continuous 48 V / 240 W operation; temperature rise stays within USB-IF limits for extended sessions.

What must my laptop port support to get 8K 60 Hz video through this cable?

The host needs a USB4 Gen 3×2 or Thunderbolt 3/4 port with DisplayPort Alt Mode; USB 3.2 or USB 2.0 Type-C ports cannot drive 8K 60 Hz.
