1、[Advantages] Through this card, the two power supplies can be turn on and off at the same time, and the power of the graphics card can be allocated to the two power supplies to substitute high power power supplies to solve the problem of insufficient power supply. 2、[Working Principle] When the power is turned on, the main power supply has a large SATA power output, and the relay on the adapter board is started to work, and the auxiliary power switch is turned on to turn on the power supply. 3、[Working Principle] Since the adapter card does not participate in the power supply, there is no situation of burning the motherboard to burn the power supply. If it burns, it is usually because the power supply is overloaded, and the interface is reversed when the device is plugged in. 4、[Wiring Mode] Plug the 24PIN of the secondary power supply into the 24PIN female connector, and plug the SATA power cord of the main power supply into the adapter card, so that the secondary power supply and the main power supply can be turned on and off at the same time. 5、[Wide Application] This power supply adapter can switch two low power power supplies at the same time, thereby increasing the power of the power supply and protecting the life of the power supply and the graphics card.
