SKU CH-MNX6-H542R

A 1.5 ft USB-C cable delivering 40 Gbps data, 240 W charging and 8K or dual 4K video

Cable Length 1.5 Feet

  • 40 Gbps transfer speed for rapid SSD and eGPU workflows
  • 240 W Power Delivery 3.1 charging for laptops and phones
  • Dual 4K 60 Hz or single 8K 60 Hz video output

Thunderbolt 4 cable for 40 Gbps workflows

This 1.5 ft USB-C cable delivers up to 40 Gbps bandwidth for external SSDs, eGPU enclosures and docking stations. It suits creators and professionals who move large project files between high-speed storage and a host system. The connection also carries 8K video at 60 Hz or dual 4K at 60 Hz for multi-monitor setups.

Passive 1.5 ft length limits heat and voltage drop

At 1.5 ft the cable stays cool during sustained 240 W PD 3.1 charging sessions and 40 Gbps data transfers. No active electronics are required, so there is no fan noise or extra power draw from the cable itself. The short run keeps resistance low for reliable 48 V, 36 V and 28 V power profiles.

USB4 compliance replaces legacy USB

The USB 4.0 implementation covers USB 2.0, 3.0, 3.1, 3.2, Thunderbolt 3 and Thunderbolt 4 signalling in one cord. It handles charging, data and video simultaneously, reducing the number of different cables a workstation needs. The soft, durable jacket resists repeated bending without stiffening.

Questions about this item

How do I connect the cable for 40Gbps data and 240W charging?

Plug the USB-C connectors into Thunderbolt 4 or USB4 ports on both devices; using a USB 3.2 or USB 2.0 port will drop speed and power.

Will the PD 3.1 EPR negotiation at 48V/240W degrade over time?

The cable is rated for 240W at 48V, 180W at 36V and 140W at 28V; normal wear does not change the negotiated voltage or wattage.

What limits sustained 40Gbps transfers on a 1.5ft run?

The 1.5ft length meets Thunderbolt 4 and USB4 signal-integrity specs, so the host or device controller thermal throttle is the first limit.
