Key Features
- Compact industrial design, breaking through the space limitations The ultra-thin 3cm height and 10cm precision structure design perfectly fits all kinds of compact chassis environments, such as 1U/2U servers, small workstations and customised water-cooling systems. The innovative height-enhancing architecture flexibly solves physical interference issues between high-end graphics cards (such as RTX 4090), CPU cooling modules and chassis frames, and supports precise spacing adjustment when multiple cards are deployed side-by-side.

- Selected 4-layer high-density PCB substrate with gold-plated surface treatment ensures zero loss of PCIe 5.0 UHF signal (32GT/s) transmission and maintains 128GB/s bi-directional bandwidth performance perfectly. The special black LCP material slot with reinforced protective cover design provides excellent high temperature and wear resistance, and can withstand more than 100,000 times of repeated plugging and unplugging.

- All-round safety protection, more peace of mind Strictly following the PCIe protocol specification and adopting the power-off operation design, it completely eliminates the risk of signal conflict caused by hot-plugging. Multiple precision fixing holes on the board can be combined with M3 screws to achieve rigid reinforcement of the graphics card, effectively preventing deformation and poor contact of heavy equipment (such as 4-slot computing cards).
- Intelligent thermal optimisation for full performance release The CFD-optimised hollow structure ensures that good airflow channels are maintained during intensive deployment. Supporting additional 40mm auxiliary fan or cooling fins, it is especially suitable for 24/7 high load scenarios such as mining/AI computing.
- Full coverage of professional scenarios, expansion without boundaries Widely compatible with all kinds of PCIe 5.0 devices, including new generation graphics cards, NVMe SSD expansion cards and AI acceleration cards. Optional professional-grade test reports (including eye chart analysis, vibration test, etc.) are available to provide data protection for data centres, research labs and other demanding environments.
