ESTONE TJ-A323 USB4 cable 6.6ft 40Gbps 8K 100W

USB4 cable for 8K displays and 100 W charging

This 6.6 ft USB4 cable connects USB-C devices to monitors, docks and eGPU enclosures. It supports single 8K@60 Hz or dual 4K@60 Hz video output when the host and display both support DP Alternate Mode. Data transfers reach 40 Gbps with USB4 Gen 3×2 hosts and fall back to 20 Gbps on Gen 2 ports. The cable is backward compatible with Thunderbolt 3 hosts and peripherals.

Passive thermals with no active cooling

The cable has no fan or active components, so it produces zero acoustic noise and adds no measurable heat to the system. Power delivery follows PD 3.1, PD 3.0 PPS, PD 2.0, QC 4.0/3.0, AFC, SCP and FCP profiles, supplying up to 100 W (20 V/5 A) to the connected device. Voltage drop over the 6.6 ft length remains within USB-IF limits for full-speed operation.

Male-to-male reversible connectors simplify setup

Both ends use USB-C male plugs that insert either way up, removing orientation frustration when plugging into laptops, phones, hubs or docking stations. The black jacket resists tangling and suits professional environments. No driver, firmware or software bundle is included; the cable relies entirely on host operating-system support for USB4, Thunderbolt 3 and DisplayPort Alternate Mode.
