Thanks for the heads up. I know you said in your original post that you were looking for comments, but I wonder if I could ask a question to help me on my quest ... you've calculated that the motors will pull 4.5A. Depending on where I look I get different advise on what the 'guesstimate' total current will be. Some indicate # motors x A x 2, which in our case with the C355-P6V's will be 3 x 1.5 x 2 = 9A or # motors x A +2A = 6.5A. Any which way I think your covered, but I was wondering what 'rule of thumb' to use, because my next acquisition will be a PSU.
