Features: Due to the vertical designs of the power port, the space is compact, and the vest on the back of the graphics card exceeds 5mm. Please contact customer service to purchase a horizontal power interfaces version Due to design issue, the metal bracket limits the thickness of the graphics card to 44mm Power supply is mandatory, and it will still supply power to external devices in case of shutdown. DCsupports amaximum power supply of 120W, please pay attention to the power consumption of external devices. External graphics cards external screens, while internal screens may be limited by the CPU's processing methods, resulting in significant losses. Currently, the 10th generation CPUs more friendly to PCIE channels and light interfaces, and the performances of internal screens is considerable. For laptops or consoles with NVME solid drive interfaces, the laptop can be disassembled to connect the adapter cable, and external devices can be disassembled without the need to disassemble main device for easy operation. Regarding compatibility, mutual learning is possible, and theoretically, the compatibility probability of NVME interfaces is relatively high Specifications: Item：Notebook External Graphics Dock Types：XM25cm/9.84in XM50cm/19.7in Size:As Pictures Package Includes: 1PC External Graphics Dock note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
