The GPU-X Multi-Link XL enables an optimal connection of two or more graphics cards in an SLI or Crossfire setup. It is optimized for airflow and provides additional stability to the graphics card assembly. With just a few adjustments, the link can be switched from parallel to serial operation. A necessary serial closure is already included in the package. All common configurations for three and four graphics card setups are covered by the GPU-X Multi-Link XL. Additional configurations are possible, as two closure bridges for sealing the unused slots are also included. Additionally, the link features eight G1/4 inch threads, allowing for flexible integration into the water circuit. The unused threads can be sealed with the provided closure screws. The installation is very straightforward. The GPU-X Multi-Link replaces the connection blocks of the graphics card coolers, and no additional adapters are required. The product is compatible with all coolers from the HEATKILLER® GPU-X³ series.
