OK, this thread got way off topic from the original question which never got answered and I appologize for that.
For those that may want to know, i got my first 16 strings wired up to my controllers and ran a test.
My power supply is "certified at 80 plus bronze" but whatever the other stuff means that indicates that it should be 80% efficient.
My line voltage was 117.8
For 16 strands of 85 nodes, turned one on and held for 5 seconds while I took an amperage measurement after it stabilized then added another strand.
With nothing on power supply was drawing .6 Amps and this was only after I plugged in all the strands. Just the hub alone was drawing about 100 mA.
Strings On Amps
0 .6
1 .8
2 1.1
3 1.4
4 1.7
5 2.0
6 2.3
7 2.5
8 2.8
9 3.1
10 3.4
11 3.7
12 4.0
13 4.3
14 4.6
15 5.0
16 5.3
So according to the calculations and at 80% efficiency it should have drawn 499 watts at 12V DC which would mean that it should be 624 Watts on line voltage at 80% efficiency so @117.8 volts thats 5.29 Amps and low and behold thats what I actually got from the above measurements.
So for those that are interested you should be able to extrapolate based on the number of nodes you are running on each string on the hub and take your line voltage and the efficiency of your power supply to determine what each power supply will draw and how many you want to have on each circuit knowing your own wiring and breaker ratings.
