USB4 cable for Thunderbolt 4/3 and USB 3.2

This 3 ft USB4 cable connects USB Type-C devices including Thunderbolt 4, Thunderbolt 3 and USB 3.2 hosts. It is built for users who need certified 40 Gbps bandwidth, 100 W power delivery and 8K 60 Hz video in a single cable. The USB-IF certification guarantees electrical and mechanical compliance with the USB4 specification.

Upgrading from slower USB-C cables

Replacing a standard USB 3.2 Gen 1 or Gen 2 cable with this link removes the 5 Gbps or 10 Gbps ceiling and adds full 40 Gbps throughput plus 100 W charging. The jump is worth it when an external SSD, dock or display demands the higher data rate and power budget that lesser cables cannot sustain.

40 Gbps bandwidth and 100 W headroom

The cable comfortably handles 8K 60 Hz video over DisplayPort 1.4 Alt Mode with DSC and HBR3, dual 4K 60 Hz setups and 40 Gbps transfers to high-speed storage. It runs out when the host or device lacks USB4 or Thunderbolt 3/4 controllers, falling back to the lower speeds those ports provide.

Questions about this item

Does the 3 ft USB-C connector clear a laptop port that sits close to the chassis?

The cable is 3 ft long with standard USB-C plugs on both ends; it needs only the port depth itself and no extra mounting hardware.

What is the correct way to plug the cable in so that 40 Gbps and 100 W are active?

Insert each USB-C connector fully until it clicks; the cable is USB-IF certified and supports Thunderbolt 4/3, so no driver or firmware step is required.

Will the 8K 60 Hz video capability degrade over time and require a new cable?

The cable uses passive copper construction with DisplayPort 1.4 Alt Mode; it has no active components that wear out, so replacement is only needed if the connectors or jacket are physically damaged.
