What this cable delivers

The StarTech CC6FT20GUSB4TP is a USB4 cable with USB-C connectors on both ends, rated for 20 Gbps data and 240 W Extended Power Range delivery. It suits users who need a single cable for high-speed data, video and charging between USB-C devices.

Practical limits of USB4 20Gbps

The 20 Gbps ceiling means the link tops out at 4K 120 Hz or dual 4K 60 Hz over DisplayPort 2.1 Alt Mode with DSC and HBR3. Bandwidth above that requires a 40 Gbps cable, so this model will not drive higher resolutions or refresh rates.

Build quality and daily use

Nickel-plated connectors are rated for 10000 insertion cycles, and the TPE inner jacket with braided exterior resists wear. Shielded construction provides EMI protection, while the laser-etched USB4 markings and certified E-marker firmware ensure correct negotiation at 20 Gbps and 240 W.

Questions about this item

Should I choose the 6 ft length or look for a shorter USB4 cable?

The 6 ft (1.8 m) length suits desk-to-monitor or dock-to-laptop runs; shorter cables exist but this one keeps full 20 Gbps speed and 240 W EPR at its rated length.

What does the 20 Gbps USB4 rating deliver when I plug this cable into my laptop and monitor?

It carries 20 Gbps data plus DisplayPort 2.1 Alt Mode with DSC, HBR3 and HDR10, enabling 4K 120 Hz or dual 4K 60 Hz video simultaneously.

How does the USB-C connector and E-marker chip affect power delivery and data limits?

USB-C male ends with a certified E-marker negotiate 240 W Extended Power Range PD 3.1 and lock the link at USB4 20 Gbps, preventing fallback to lower speeds.
