So I wanted to provide an update on the power supply. My PC power supply worked fine until I tried to actually run a gcode. once I tried to do a dry run, it shut off. After doing that, I hooked up a left over 100kom resistor to the 5v rail of the power supply and a ground since I had this left over. This did not resolve the problem. I did a little research and found that if the resistor is too large then it will not draw enough amperage hit that constant draw requirement to keep the PS on. As a test, I hooked up a case fan up to the 5v rail and ground. Doing this took care of the problem. The power supply now runs like a champ.

Summary: if you run of a PC power supply and having issues, then make sure that you are pulling enough amps from the 5v rail. Smaller resistors are better here.
