One Cable for Data Video Power

This USB4 cable handles 40 Gbps transfer 100 W charging and 8K 60 Hz video in a single 3.3 ft run. It suits creators moving large SSD archives gamers driving high refresh monitors and professionals docking a laptop to dual 4K screens. Buyers who need longer reach or legacy USB A connectors should look elsewhere.

40 Gbps Decides Fit

The 40 Gbps ceiling is the spec that determines whether the cable matches your workflow. NVMe enclosures eGPU docks and Thunderbolt 3 or 4 hosts can saturate this link while slower 10 Gbps or 20 Gbps cables would bottleneck them. If your gear tops out at 10 Gbps the extra headroom goes unused.

Plug In and Go

Both ends are USB C so installation is a simple insert no drivers required. The most common issue is expecting 8K or dual 4K from a host port that only supports DisplayPort 1.4 or lower. Charging hits 100 W only when the charger and device both negotiate PD 3.1 EPR at 20 V 5 A.

Questions about this item

How fast will a 2.5 GB file actually move across this 40 Gbps cable?

Real-world throughput reaches up to 2.8 GB/s read and 2.1 GB/s write, so a 2.5 GB file transfers in roughly one second.

What does the USB4 40 Gbps rating limit when I plug this into a Thunderbolt 3 or 4 port?

The cable caps at 40 Gbps data, 100 W power delivery and 8K at 60 Hz video; Thunderbolt 3 or 4 hosts will not exceed those limits.

Will the 3.3 ft length reach from a laptop on a stand to a monitor on the desk behind it?

At 3.3 ft the cable spans a typical laptop-to-monitor gap on the same desk; allow slack for routing around stands or docks.
