Sorry for replying to my own thread but I did some more research and I guess I have another question. On the box on one of the power cords (a regulator?) It says Output: +5v 3.0A, 12v 2.0A.
Does this mean I need to take into account both the 12v and 5v into my total amp calculation?
So according to the Telek's Calculator
I require 4.75A on the 5v, 2.7A on the 12v. I then need to add these 3 devices I mentioned above. My total watts is about 142. But my 12v is like 6A. Not sure what to do or if I am even in the right ball park.
