What this cable delivers

A USB4 Gen 3x2 cable rated for 40Gbps data transfer, 240W Power Delivery 3.1 and 8K@60Hz video output. Grey, male-to-male USB-C connectors, 4 ft long. Works with any USB-C device, dock or eGPU enclosure.

When the upgrade makes sense

Replaces older USB-C cables limited to 100W or 10Gbps when you need the full 240W Extended Power Range or 40Gbps throughput. Worth the jump only if your charger, host and device all support PD 3.1 EPR and USB4 Gen 3x2; otherwise the extra headroom goes unused.

Installing and common pitfalls

Plug both ends in — fully reversible, no driver required. Most issues come from mismatched ports: a 5Gbps or 10Gbps host will cap speed, a non-EPR charger will cap power, and a display without DSC or sufficient bandwidth will fall back to 4K. Use the shortest practical length for reliable 40Gbps operation.

Questions about this item

Does the 4 ft length reach a monitor on a typical desk?

The cable measures 4 ft, which spans most desk setups between a laptop and a single 8K display or dual 4K monitors without strain.

Is any driver or firmware step required before the first 40 Gbps transfer?

No driver is needed; the USB4 Gen 3x2 connection is plug-and-play, but both host and device must support USB4 to reach the 40 Gbps ceiling.

Will the 240 W rating degrade if I coil the cable during daily use?

The PD 3.1 EPR design handles 48 V at 5 A continuously; normal coiling does not reduce the 240 W capability as long as connectors stay clean.
