Purpose and audience

The StarTech CC3FT40GUSB4TPW is a USB4 cable rated for 40 Gbps data and 240 W power delivery. It suits professionals who connect high-resolution displays, fast storage or docking stations to a USB4 or Thunderbolt host.

Connectors and daily handling

Both ends carry USB-C USB4 male plugs, so the cable fits any USB-C port without orientation worries. At 3 ft (91 cm) it reaches across a desk while keeping the signal path short enough for full-speed operation. The white jacket resists visible wear in studio or office lighting.

Interface limits

The link tops out at 40 Gbps, so it cannot carry uncompressed video beyond 8K 60 Hz or 4K 240 Hz with DSC. Power delivery stops at 240 W EPR PD 3.1, ruling out higher-wattage charging scenarios. Thunderbolt 4 compatibility is supported, but longer runs would need active or optical alternatives.

Questions about this item

Does the USB4 interface on this cable cap at 40 Gbps in practice?

Yes, the USB4 cable delivers up to 40 Gbps data speed and supports DisplayPort 2.1 Alt Mode for 8K 60Hz or 4K 240Hz video with DSC.

What physical length and connectors does the CC3FT40GUSB4TPW need to fit my setup?

The cable is 3 ft (91 cm) long with USB-C male connectors on both ends for direct device-to-device or device-to-dock connections.

How is this Thunderbolt 4 compatible cable installed, and what step do people often get wrong?

Plug each USB-C end firmly until it clicks; the common mistake is not seating the connector fully, which can limit power delivery to 240W EPR or drop video to a lower mode.
