1. Stability: When designing the product, taking into account the stability of the rack, add braces at both ends of the bracket to form a triangular support. The sturdy bracket can better avoid the poor contact of the PCI card caused by the distortion of the rack due to the insufficient strength of the rack.2. Strong compatibility: The product supports multiple graphics card installation, and the length and height of the graphics card are not limited by the bracket.3. Heat dissipation: a 12cm fan fixed position is reserved at the rear (a fan is installed depending on the length of the graphics card), and the product has a good heat dissipation effect.4. Fastening: Although this product has only two screws to fix the power supply, the thickness of the material and the reinforced design of the structure are sufficient to fasten the power supply.5.
