USB-IF Certified USB4 Cable Delivering 40Gbps Data, 240W Power Delivery 3.1, and 8K 60Hz Video Over a Single USB-C Connection
The StarTech 1M-40G-USB4-CABLE is a 1-meter (3.3ft) USB4 cable that delivers full USB4 capabilities including 40Gbps data transfer, 240W Power Delivery 3.1 Extended Power Range, and 8K 60Hz video output through a single USB-C connection. USB-IF certification with an integrated E-Marker chip guarantees consistent power delivery and data rates across all compatible devices, while backward compatibility with Thunderbolt 3/4, USB 3.2, and USB 2.0 ensures universal connectivity.
DisplayPort 1.4 Alt Mode with DSC, HDR, and HBR3 support drives up to 8K 60Hz or 4K 120Hz displays directly from USB-C and Thunderbolt laptops. The 240W EPR charging supports high-performance laptops including the MacBook Pro M3 Pro and M3 Max, delivering full power and 40Gbps data over the same cable to docking stations, external storage, and portable monitors. Connector markings identify data, video, and power specifications at a glance for quick cable identification in mixed environments.
Where the StarTech USB4 Cable Fits
- High-performance laptop workstations connecting to Thunderbolt docking stations where the single USB4 cable delivers 40Gbps data, 8K video, and up to 240W charging simultaneously, eliminating multiple cable connections between the laptop and dock
- Creative and engineering workflows requiring maximum bandwidth to external NVMe storage where 40Gbps PCIe 3.0 tunneling provides fast file transfers to USB4-enabled enclosures and drives without saturating the connection during simultaneous display output
- Multi-device environments needing one certified cable for charging, data, and video where USB-IF certification guarantees reliable 240W EPR power delivery to high-wattage laptops like the MacBook Pro M3 Max while maintaining full USB4 data and display capabilities
What the StarTech USB4 Cable Delivers
- 40Gbps USB4 with PCIe 3.0: Full USB4 bandwidth for data transfer to external storage, docking stations, and PCIe devices. Backward compatible with Thunderbolt 3/4, USB 3.2, USB 3.0, and USB 2.0 for universal connectivity across device generations.
- 240W Power Delivery 3.1 EPR: Extended Power Range charging supports high-performance laptops requiring maximum wattage, including 16-inch MacBook Pro models. USB-IF certified E-Marker chip ensures safe, consistent power output to connected devices.
- 8K 60Hz DisplayPort 1.4 Alt Mode: Drives up to 8K 60Hz or 4K 120Hz displays with Display Stream Compression, HDR, and High Bit Rate 3 support. Single-cable video output from any USB-C or Thunderbolt laptop to compatible monitors.
- USB-IF Certified Construction: Rigorous compliance testing verifies electrical and mechanical standards for guaranteed USB4 performance. Nickel-plated connectors, coaxial wire with Mylar and aluminum shielding, and TPE jacket with strain reliefs deliver durability and EMI protection.
- Visual Cable Identification: Connector markings display data speed, video capability, and power rating for instant identification. Eliminates guesswork when selecting the correct cable from a collection of similar-looking USB-C cables.
