Answered Printer seems to power cycle 10 mins into print?

My stock power supply got fried somehow and I couldn't figure out how to fix it, so I recently purchased a Mean Well 12V 350W switching power supply.
I just wired it up and installed it. It starts up and seems to run fine. When I start a print, it prints great for ~8-12 mins, then it seems to do some sort of power cycle, where the whole machine loses power for a second or two (including my LCD screen). It starts itself back up after about a second and then just sits there. When it comes back on, my LCD screen displays that the printer is cooling down to 0 degrees C. I also replaced the RAMPS board fan with a Noctua of the same size. The thing is so darn quiet that I'm not sure if its actually running. Is the fan plug and play? Or do I have to change something in the printer's code to recognize the new fan? Thanks all for the help.

 

Thanks for the response. I am using Cura and I can't find much on how to access the gcode monitor there; do you know how? Otherwise I'll just try a print with MatterControl and observe from there.
