So, could I actually just use an ATX PSU to power the whole printer? Cause I have an even better 750watt from an old gaming pc that broke down on me. I think it has multiple rails, I know the 1600w in my current pc has a bunch of them, but I think I remember that one has at least 2. Just plug those 2 rails into the 2 pairs of pos and neg terminals then? Sorry if that's a newbish question, but I have literally 0 electronics and engineering experience prior to what I've taught myself here.
