SMUGDESK USB4 cable USB‑C to USB‑C 240W 40Gbps 8K 3.3ft black

SKU CH-P5Z7-07Y06

USB4 cable delivers 240W charging, 40Gbps data transfer and 8K@60Hz video over a 3.3ft USB‑C to USB‑C link

Cable Length 3.3 Feet

  • Charge at up to 240W with PD 3.1 Extended Power Range
  • Transfer data at 40Gbps with USB4 Gen3x2
  • Drive a single 8K display at 60Hz or dual 4K at 60Hz
  • Backwards compatible with 20Gbps, 100W and lower USB-C gear
  • 3ft reversible USB-C to USB-C cable for docks, eGPU and chargers

Ready for 240W charging

This USB4 cable carries up to 240W at 48V with PD 3.1 extended power range, so it can fast-charge phones, tablets, laptops and even power-hungry gaming notebooks from a single compatible charger. The bi-directional USB-C connectors are reversible and rated for Gen 3x2 speeds up to 40Gbps. It also supports 8K@60Hz video or dual 4K@60Hz displays when used with capable hosts.

Check your host and charger

Verify that your device and power supply both support USB PD 3.1 EPR and the USB4 Gen 3x2 data rate; otherwise the cable will fall back to 20Gbps (Gen 2) or lower power levels such as 100W, 180W or below. Video modes like single 8K@60Hz or 4K@120Hz require a host controller that can drive those resolutions over USB-C. Two cables are needed for dual 4K@60Hz monitors.

Replaces older USB-C cables

This single cable supersedes separate USB 2.0, USB 3.0, USB 3.1 and USB 3.2 cords as well as Thunderbolt 3 and Thunderbolt 4 cables for charging, data and video. The upgrade is worth it when you need 240W charging headroom, 40Gbps throughput for external SSDs or eGPUs, or 8K display output that legacy cables cannot deliver.

Questions about this item

Does the cable include a charger or do I need to supply my own 240W PD 3.1 power adapter?

The box contains only the USB-C to USB-C cable. A compatible PD 3.1 charger capable of 48V/5A must be purchased separately to reach 240W.

Should I choose this 40Gbps USB4 Gen 3x2 cable or a slower 20Gbps version for an eGPU enclosure?

Pick this 40Gbps Gen 3x2 cable; the 20Gbps Gen 2 alternative cannot saturate an eGPU link or drive dual 4K@60Hz displays.

Will the advertised 40Gbps throughput actually appear when I connect my laptop and SSD?

You will see up to 40Gbps only if both host and device support USB4 Gen 3x2; otherwise the link falls back to 20Gbps.
