Power supply for 2gig GC3 and SP1/2

My home has a central location that all my original panels were wired to. When I updated to the GC3, I disconnected the other panels and plugged in the 14V 1.7A adapter and connected it to the wiring running to the GC3.

I am thinking of adding back additional panels such as the SP1 or 2, but am wondering since I currently only have room for the single adapter to be plugged in, is there a higher power 14V adapter available or that would be compatible if I wanted to power everything from a single adapter.

Has anyone had any luck installing or finding a 14V 3.4A or higher adapter?

I could not recommend using anything other than the provided power supply for each panel being utilized.

I would recommend using a power strip or UPS for the multiple transformers. I would strongly discourage alternative power sources.
