The rated 230W power supply has a limited+12V output capacity, and is usually * dummy marked, * so it is not suitable for any independent graphics card that needs independent power supply. Whether it is a GTX650, GTX650Ti or other independent graphics card that needs independent power supply, please consider replacing the rated 400W or above brand power supply.
PS: The computer is yours and has nothing to do with others. Now the living standard has improved, the computer configuration has become better and better, and the price has become lower and lower. But many people are still like beggars who refuse to spend more money on the chassis and power supply. I don't know whether it is smart or foolish. Welcome to your seat.
