1、 Because the current high-power power supply is relatively expensive, the line can be used to switch the power of two power sources at the same time, thereby increasing the power of the power supply. 2、 Through this card, two power sources can be turned on and off at the same time, and the power of the graphics card is distributed to two power sources to replace the high-power power source. 3、 Easy to use, just plug the 24PIN of the main power supply into the 24PIN female head, the other end is plugged into the motherboard, and the secondary power supply detection 4P power cord is plugged into the riser card, so that the secondary power supply and the main power supply can be simultaneously switched. Machine, protect power and graphics card life. 4、 Made of high quality materials, the product is sturdy and durable. 5、 The product is small in size, light in weight, easy to install and easy to use.
