LUOM TJ-A323 USB4 cable for creative professionals

The LUOM TJ-A323 is a USB4 cable built for creators who need 8K@60Hz video output and 40Gbps data transfers between USB-C devices. It supports Thunderbolt 3 and 4 hosts, making it suitable for eGPU enclosures and dual 4K display workflows. Buyers who need longer runs for fixed installations should check length limits before ordering.

Sustained 40Gbps throughput and 100W delivery

The cable maintains 40Gbps bandwidth under continuous load, moving up to 2.8GB/s read and 2.1GB/s write when paired with Gen3 ports. Power Delivery 3.1 at 20V/5A supplies up to 100W for gaming laptops without throttling. Bandwidth drops to 20Gbps on Gen2 ports, so verify your host controller generation.

Plug-and-play USB-C male-to-male

Reversible USB-C male connectors seat firmly in Thunderbolt 4, Thunderbolt 3 and standard USB-C ports. No drivers are required for video, data or charging functions. The 6.6ft length adds cable management bulk in tight desktop setups. Users needing angled connectors or shorter tails for portable docks will find the straight design less convenient.
