SKU CH-A36Y-RMK5V

USB4 cable delivers 40Gbps data, 240W charging and 8K@60Hz video over 5 ft

Cable Length 5 Feet

  • Charge laptops at up to 240W via PD 3.1
  • Move large files at 40Gbps with USB4 Gen 3x2
  • Drive an 8K display at 60Hz over a single cable
  • Works with Thunderbolt 4, 3 and earlier USB-C gear
  • 5 ft length gives desk flexibility without signal loss

What this cable does

The SMUGDESK USB4 cable carries 40Gbps data, 240W charging and 8K video at 60Hz over a single USB C to USB C link. It is built for creators and professionals who need maximum throughput between laptops, docks, monitors and high-speed SSDs.

Thermals noise and power

Passive construction means no fan noise and no active cooling to fail. The cable handles the full 48V 5A Extended Power Range without overheating in normal desktop use, staying within USB4 Gen 3x2 thermal limits during sustained 240W charging or 40Gbps transfers.

The deciding specification

If your workflow demands 40Gbps bi-directional bandwidth and 240W Power Delivery 3.1 over USB4 Gen 3x2, this cable meets that bar. Buyers who only need 10Gbps or 100W charging will not use the extra headroom this cable provides.

Questions about this item

How do I plug the USB-C male connectors in the right orientation for 40Gbps and 240W?

The connectors are reversible; insert either side up. The step people miss is confirming both host and device support USB4 Gen 3x2 and PD 3.1 EPR — otherwise the link falls back to a lower speed or wattage.

When will the cable’s 240W charging or 40Gbps throughput start to degrade?

The cable is passive copper rated for the full USB4 Gen 3x2 spec. No maintenance is needed, but repeated sharp bends near the plugs can fatigue the internal wires and reduce both power and data margins over time.

What is the first limit I hit when running 8K@60Hz and 240W charging together for hours?

The 5 ft length stays within the USB4 passive-cable budget, so the first limit is usually the host’s thermal throttle on its USB-C controller — not the cable itself — which may drop the link to 20Gbps or lower the PD voltage to protect silicon.
