Because the current high-power power supply is relatively expensive, using this can switch the two power supplies with low power at the same time, thereby increasing the power of the power supply.When connecting 5 graphics cards to swipe coins at the same time, the power of the power supply is not enough, and the high-power power supply is out of and the is quite expensive. The adapter card here comes in . Through this card, the two power supplies can be switched at the same time. The graphics card power is allocated to the two power supplies to substitute high-power power supplies.Precautions:Be to recognize the direction when plugging in, and t plug it in reverse or off-position to prevent the device from being burned.
