So I am upgrading my computer and I am getting a graphics card from my friend and the only thing i didnt feel i really need to upgrade is my power supply, however i dont think that my power supply has the correct pins to support a 770. I have a GTX 650 right now. My PSU has two four pin connectors and then whatever the graphics card comes with. Any help is appreciated thanks!
