1. Efficient Heat Dissipation: The aluminum alloy heat sink backplate, CNC cutting process, gold-plated extended terminals, and built-in heat pad maximize heat dissipation, ensuring optimal performance. The design effectively eliminates heat, enhancing overall cooling efficiency. 2. High-performance Design: With support for up to 600W output, this adapter is compatible with RTX4090 graphics cards. It a double-thickness copper plating of 2oz and a multi-layer PCB design, ensuring efficient heat dissipation and stable current transmission. Please note that using power outputs exceeding 600W for extended periods may damage the equipment. 3. Stress-free Connection: The 90-degree angled design allows effortless connection between the power cable and GPU interface without exerting pressure on the graphics card interface. This design reduces stress on connectors and cables, providing enhanced safety during assembly and long-term usage. 4. Customized Compatibility: This adapter is specifically designed for 4090, 4080, 4070 Ti, 3090 Ti, and other compatible graphics cards. The 90-degree angle adapter is particularly useful for building in larger spaces and offers greater flexibility when it comes to cable routing. 5. Improved Cable Flexibility: By utilizing this adapter, you gain more flexibility in cable management, making it easier to route cables in various directions.
