FQA Question 1: Why is power-free better than external power supply?
Answer: External power supply uses wires to connect external 5V to the interface. Voltage loss will occurthrough wires. The larger the load, the greater the loss, the more unstable there will be. The power-free board takes 12V. After voltage reduction, interference removal and voltage stabilization, the output is stable 5V, and loss compensation is added, so there will be no shortage of power supply.
Question 2: Will the main board interface power fetch affect the main board?
Answer: The industry standard of PCI-e interface of motherboard is to provide 75W power. The full load workof extended card is 40W, which occupies only half of the design standard. Normal use rarely exceeds 10W, sothere is no need to worry about the impact on motherboard.
Question 3: What are the advantages of this product?
Answer: 6A Independent PowerSupply2-phase power supply module2-way independent power supply2 Independent Insurance2 working independentlyMutual non-influenceSay goodbye to the shortage of power supply.
