Effectively solve the lack of PCI-E interfaces on the motherboard, 1 interface can be expanded to 4, with 4 sets of VER 12X graphics card extension cable sets, a temperature sensor and digital temperature display are added, which can intuitively display the ambient temperature around the graphics card in real time. 4 solid capacitors per card, voltage regulation, over-current protection, and more stable power supply. The plug-in design is adopted, which can be directly connected to the motherboard interface without an extension cable, and can be fixed on the chassis, which greatly improves the stability and reliability. The main control board adopts the PCI-E interface direct power supply mode, no external power cord is required, so that the main control board power supply is not by the outside world, and the stability is higher. Reduce the number of adapters and cables. One line goes directly to the interface, effectively reducing interface interference and line loss, ensuring data reliability and improving work efficiency. New BIOS, more compatible with motherboards and graphics cards, with lower power consumption. Reduce interference between USB interfaces and enhance data integrity.
