HOOCCC OCuLink GPU Dock Docking Station with Non-Detachable 50cm OCuLink Cable, Metal Bracket, PCIe 4.0 x4 to x16 64Gbps, Open-Frame eGPU Dock for Mini PC, ATX/SFX PSU Compatible, Black

OCuLink PCIe 4.0 x4 Open-Frame GPU Dock External eGPU Expansion Station with Integrated Cable & Metal Bracket (Black / White)

Unlock true desktop-class PCIe expansion for your mini PC, handheld gaming console, or thin-and-light laptop. This open-frame GPU dock leverages a high-speed OCuLink (SFF-8611) PCIe 4.0 x4 interface to deliver a direct, low-latency connection to external graphics cards and other PCIe peripheralsno Thunderbolt bottlenecks, no unstable signal paths.

Permanent, Direct-Wired OCuLink Cable

The dock features a non-detachable, integrated OCuLink cable permanently soldered to the board. This design eliminates wobbly plugs, loose contacts, and intermittent dropouts, ensuring optimized data transfer performance and a reliable link to your host device every time you power on.

Spacious Open-Frame Layout

Housed on a rigid metal base with a matching support bracket (available in Black or White finishes), the open-air structure provides generous clearance for modern, bulky graphics cards up to 360 mm in length and 150 mm in height. Superior airflow keeps even high-TGP GPUs running cool under load.

Broad PCIe Device Support

While built primarily as an external GPU (eGPU) dock, the full-size PCIe slot also accommodates PCIe network cards, capture cards, sound cards, and other add-in cards. It is compatible with ATX, SFX, and Small 1U power supplies, giving you freedom in choosing the right PSU for your build.

Plug, Power, and Sync

Dedicated PCIe power connectors on the board supply your installed card directly. The dock also supports synchronized power on/off with your host system for hassle-free startup and shutdown. With the pre-mounted main board and included metal frame, assembly is quick and tool-friendly.

Whether youre building a compact eGPU setup, a portable AI/rendering workstation, or an open-air test bench, this OCuLink GPU dock delivers the bandwidth, stability, and physical space you need.

Note: Host device must feature an available OCuLink (SFF-8611/SFF-8612) port or compatible PCIe 4.0 x4 output to connect.
