I did mention what power supply I had in my first post. Its a brand new Happ 15amp switching power supply from ArcadeShop. And I'm pretty sure I do need all the voltages it supplies cause I'm not just running a MisterCade I also have a BitKit and original Pac-man and Ms Pacman boards all running in a RiddleTV switcher. The MisterCade is the only board that has a problem with the power supply.
