SMUGDESK

SMUGDESK Thunderbolt 5 Cable 3.3ft 80Gbps 240W

SKU CH-20V1-H6BEE

Transfers data at up to 80 Gbps, delivers 240 W charging, and drives dual 8K or triple 4K 144 Hz displays over 3.3 ft

Cable Length 3.3 Feet

  • 80Gbps bi-directional bandwidth for rapid file transfers with USB4 Gen 3x2
  • 240W Power Delivery 3.1 fast-charges laptops and devices at 48V
  • Drives dual 8K or 6K displays at 60Hz for expansive workspaces
  • Backward compatible with Thunderbolt 4, 3 and USB 2.0 through USB 3.2
  • 3ft reversible USB-C male connectors enable plug-and-play convenience

Thunderbolt 5 Cable for 240W Power Delivery

This Thunderbolt 5 cable delivers up to 240W of power through USB Power Delivery 3.1 Extended Power Range. It supports bi-directional charging for laptops, phones and SSDs that accept PD 3.1, PD 3.0 PPS, QC 4.0 or AFC protocols. The cable is backward compatible with 180W, 140W, 100W and lower power profiles. A 240W EPR charger and a device that negotiates 240W are required to reach the maximum rating.

80Gbps Bandwidth and DisplayPort 2.1 Video Limits

The cable provides up to 80Gbps of bi-directional data bandwidth with USB4 Gen 3x2 devices and up to 120Gbps with Bandwidth Boost for display traffic. It carries DisplayPort 2.1 signals for dual 8K or 6K at 60Hz, triple 4K at 144Hz, or a single 4K panel at 540Hz. Video performance depends on the host controller and monitor supporting the same DisplayPort UHBR rates and DSC compression.

3.3ft Length and Compatibility Headroom

At 3.3ft the cable suits desktop and bench setups where the host and peripheral sit close together. It handles Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4 and all legacy USB 3.2 and USB 2.0 devices without adapters. Builders who need longer reach for rack-mounted gear or users who require optical cable lengths will find the fixed 3.3ft length a constraint.

Questions about this item

Should I choose the 3.3 ft length or a longer Thunderbolt 5 cable?

The 3.3 ft length keeps signal integrity for the full 80 Gbps data rate and 240 W power delivery; longer cables can reduce both speed and charging capability.

What does the 80 Gbps figure mean when I connect my SSD or dock?

You get up to 80 Gbps bi-directional throughput with USB4 Gen3x2 devices, and Bandwidth Boost can push video traffic to 120 Gbps for high-refresh displays.

Which USB standard does this cable use and what does it cap in practice?

It uses the latest USB4 Gen 3x2 standard, capping data at 80 Gbps, video at dual 8K 60 Hz or 4K 540 Hz, and power at 240 W with PD 3.1 EPR.
