Features: brand new and high quality Stability: When designing the product, taking into account the stability of the rack, add brace 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. Strong compatibility: The product supports multiple graphicscard installation, and the length and height of the graphicscard are not limited by the bracket. Heat dissipation: a 12cm fan fixed position is reserved at the rear (a fan is installed depending on the length of the graphicscard), and the product has a good heat dissipation effect. 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. Cold-rolled steel plate material: This product is made of high-quality cold-rolled steel plate material, with fine workmanship, very good quality and long service life.
