So far so good. I have tried 3 different computer power supplies and only 1 has worked so far. I am not sure what the difference between them was but they all had plenty of power but if you get random brown outs on your machine it’s the power supply. The one that does work is nice because I use it’s fan to cool the ramps as well. I want to do something alone the lines of the table in the “coffee with the MPCNC” video for my power supply and board an all that, nice tool mount holder space and everything.
