SMUGDESK 1.6FT USB4 Thunderbolt 5 Cable 240W 80Gbps

SKU CH-1RWB-K785T

A 1.6 ft USB-C cable delivering 240 W charging, 80 Gbps data and 16K@60 Hz display support for Thunderbolt devices

Cable Length 1.6 Feet

  • Charges devices at 240W for rapid power delivery
  • Transfers data at 80Gbps with bandwidth boost to 120Gbps
  • Drives one 16K display at 60Hz or dual 8K displays
  • Works with Thunderbolt 3 and 4 devices and older USB standards
  • Supports 4K resolution at 540Hz for high-refresh visuals

What this cable is

A USB-C to USB-C cable built to the USB4 V2 and DisplayPort 2.1 standards, delivering 80 Gbps bi-directional bandwidth and up to 240 W power delivery. It is made for professionals connecting high-resolution displays, fast storage or eGPU docks to Thunderbolt 3, 4 or 5 hosts. The 1.6 ft length suits desktop setups.

Bandwidth and power that decide fit

The single figure that determines whether this cable matches your workflow is the 80 Gbps data rate combined with 240 W charging. If your host and peripheral both support USB4 V2 or Thunderbolt 5 you gain the full 80 Gbps and 120 Gbps boost mode; older USB 3.2 or Thunderbolt 3 devices will fall back to their native speeds and lower wattage.

Build integration

The cable carries DisplayPort Alt Mode video so it can drive one 16K@60 Hz panel or dual 8K@60 Hz panels without a separate video lead. It replaces a dedicated charge cable by supplying up to 240 W to a laptop or dock. Backward compatibility with USB 2.0, 3.0, 3.1 and 3.2 means existing peripherals still work, but they will not reach the 80 Gbps or 240 W ceiling.
