USB4 Gen 3x2 cable for high-speed workflows

This USB-C to USB-C cable delivers up to 40 Gbps data transfer and 240 W power delivery using the USB4 Gen 3x2 standard. It serves professionals who move large media files between workstations and need reliable charging for power-hungry laptops. The 5 ft length suits desk and bench setups.

Replaces slower USB 3.x or Thunderbolt 3 cables

When a current cable caps at 10 or 20 Gbps and 100 W, this link removes both bottlenecks in a single run. The upgrade is worth it if the host, dock and device all support USB4 Gen 3x2 and PD 3.1 EPR; otherwise the extra headroom stays unused.

Sustained 40 Gbps and 240 W without throttling

An integrated E-Marker chip negotiates voltage up to 48 V and 5 A, keeping the link stable during long transfers or continuous 140 W laptop charging. Nylon braiding resists heat build-up, so the cable maintains rated throughput and power during extended sessions.

Questions about this item

What USB-C port version does the cable need on each device to reach 40 Gbps?

Both devices must support USB4 Gen 3x2 or Thunderbolt 3/4 to achieve the 40 Gbps rate.

How do I connect the cable so the E-Marker chip negotiates 240 W charging?

Use a 240 W EPR PD 3.1 charger and a device that accepts 48 V 5 A; plug either end into the charger and the other into the device — connectors are bi-directional.

When should I replace the cable if the E-Marker chip stops regulating power correctly?

Replace it if devices no longer charge at the expected wattage, if charging stalls at lower levels like 100 W or 60 W, or if the cable shows physical wear on the nylon braid.
