SMUGDESK 80Gbps Thunderbolt 5 Cable 4.9ft 240W

SKU CH-2QP0-PYZS1

A USB-C cable delivering 80Gbps bandwidth, 240W charging and 16K@60Hz video over 4.9ft

Cable Length 4.92 Feet

  • Charges up to 240W with 48V 5A power delivery
  • Transfers data at 80Gbps with USB4 Gen4 bandwidth
  • Drives dual 8K displays at 60Hz via Thunderbolt 5
  • Supports 4K at 540Hz for high-refresh gaming
  • Backward compatible with USB 2.0 3.0 3.2 and Thunderbolt 3

What this cable delivers

The SMUGDESK Thunderbolt 5 cable provides 80Gbps bandwidth and 240W charging over a 4.9ft length. It supports single 16K@60Hz or dual 8K@60Hz video output, plus triple 4K@144Hz configurations. Data transfer reaches up to 80Gbps with Bandwidth Boost up to 120Gbps for display traffic. The cable is backward compatible with USB 2.0, USB 3.2 Gen 1, Gen 2, Gen 2x2, Thunderbolt 3, Thunderbolt 4 and USB4 devices.

Installation notes

Connect the USB-C ends to the host and peripheral; the cable handles power, video and data simultaneously. Actual data speed depends on the port generation used: up to 20Gbps on Gen2, 40Gbps on Gen3 and 80Gbps on Gen4. To reach 240W charging, both the charger and the device must support 48V/5A power delivery. Video bandwidth scales with the host controller, so dual 8K or triple 4K setups require a Thunderbolt 5 or USB4 V2 source.

Check before ordering

Verify that your laptop, dock or monitor has a USB-C port rated for Thunderbolt 5, USB4 V2 or at least Thunderbolt 4 to use the full 80Gbps bandwidth. Confirm the power adapter can deliver 48V/5A if you need 240W charging. Ensure the 4.9ft length suits your desk layout. This cable will not add Thunderbolt capability to a USB-only port, and it cannot exceed the display or data limits of the host controller.

Questions about this item

How can I verify the cable is delivering the full 80Gbps bandwidth after connecting it?

The cable supports up to 80Gbps with USB4 Gen4 ports; actual speed depends on the host and device ports used, with Gen3 ports reaching 40Gbps and Gen2 ports reaching 20Gbps.

What comes in the box and do I need to buy a charger separately for 240W charging?

The package contains the 4.9ft Thunderbolt 5 USB-C to USB-C cable; a compatible 240W (48V/5A) charger must be purchased separately to achieve maximum power delivery.

Which version should I choose for dual 8K@60Hz monitors versus a single 4K@540Hz display?

This single cable handles both scenarios: it supports dual 8K/6K@60Hz or triple 4K@144Hz setups, and also drives a single 4K@540Hz display via Bandwidth Boost up to 120Gbps.
