Connects a desktop graphics card to a laptop or Mini PC via OCuLink SFF-8612 at PCIe 4.0 x4 64Gbps using a 50cm cable, with a detachable dock supporting standard ATX power supplies

  • PCIe 4.0 x4 delivers 64Gbps bandwidth for high-performance graphics
  • Supports full-size cards such as RTX 4090 and AMD RX 7900 XTX without length limits
  • Ultra-thin 0.5mm flat cable with full shielding reduces EMI and protects ports from damage
  • Detachable dock design with 10 gold-plated contacts improves conductivity and resists oxidation for stable operation
  • Standard ATX power supply compatibility with dual screw mounting ensures secure GPU power delivery

PCIe 4.0 x4 eGPU Dock

The LORDWORLD dock connects a laptop or Mini PC to a full-size graphics card through an OCuLink SFF-8612 interface running at PCIe 4.0 x4. It targets users who need desktop-class GPU performance without a desktop chassis.

Detachable dock with 0.5 mm flat cable

The enclosure separates for portability and uses a 10 gold-plated contact PCB to reduce oxidation-related crashes. A 50 cm ultra-thin SFF-8611 Male-to-Male cable with full-coverage shielding replaces rigid OCuLink leads, while dual screw mounts secure a standard ATX power supply top and bottom.

OCuLink requires powered-down connection

The interface does not support hot plugging, so the host must be shut down before attaching or removing the cable. This constraint suits stationary setups but rules out frequent connect-and-disconnect workflows.
