Derek,
I have a 10A 12V transformer (in fact I use two!) to feed all my cameras (Lodestar, DMK51, ATiK 314) and the USB powered Hub (through a step down converter 12V to 6V)
The other powers the mount etc - I have a 12v to 15V converter for the NEQ6.
A Turnigy power monitor is also in the loop to check voltage and power.
HTH
Better check on which plug to order for our system.
Or just buy one off evay, plenty of 12v 5a LED power supplies on ebay au. I use one for my 1600. Easy to pick up some plugs at Jaycar, in fact Jaycar has a power supply as well. Lots of choices.
