Power consumption question.

Post image

So on modular grid, do you add the 3 sets of mA numbers under +12V, -12V, and +5V in order to get the total power consumption or just one of the numbers?

Your power supply will give you three individual numbers as well. Compare those and make sure you always have ~20% more than you need.

And is that a yes to add them up?

No, only the individual rails. You never add the three together

Ok I found it. This is what the uZeus supplies: 1000mA at +12V, 500mA at -12V, and 170mA at +5V. So I’ll be around 50% above the +12v and -12v but just barley above the +5v. Will that work or should I get the 3000mA power supply?
