Silkland USB4 Cable 80Gbps for Thunderbolt 4/5 1.5m

This USB4 cable delivers up to 80Gbps bidirectional data transfer and is compatible with Thunderbolt 5, making it well suited for transferring large media files, running demanding multi‑screen setups, or docking a high‑performance workstation. Designed for professionals who need fast, reliable connectivity, it also supports up to 120Gbps bandwidth for video, enabling double 8K/6K at 60Hz or triple 4K at 144 Hz while handling simple 4K at 540 Hz when required.

The Silkland USB4 Cable provides robust power delivery and smart current adjustment to protect connected devices. It supports PD3.1 charging up to 240W and is compatible with a range of other power levels, which helps keep laptops, external GPUs, and docks charged during intensive workloads. The cable features USB‑IF certification for stable performance and long‑term reliability, and the built‑in E‑Marker chip ensures safe, efficient power management across devices.

This cable is built for versatility and durability. Its rounded, slim housing is designed to fit through protective cases and phone covers, while a 48‑strand braided weave reduces tangling and enhances resilience. The aluminium housing improves heat dissipation, and a multi‑layer EMI shield plus high‑conductivity OFC wires help maintain signal quality across demanding setups. It also supports DisplayPort 2.1, broadening compatibility with modern displays and multi‑screen configurations 🟣. For users who work with laptops, desktops, SSDs, docking stations, or external GPUs, the cable offers a reliable connection in busy environments.

Key Points

This high‑capacity USB4 cable is designed to work with complex workstations and high‑end devices. It supports dual 8K or 6K displays at 60 Hz, or three 4K displays at 144 Hz, with a simple 4K at 540 Hz option when needed. The combination of USB‑IF certification and advanced bandwidth management helps ensure stable data transfers and predictable performance during design, editing, and rendering tasks.
