I’d recommend getting a higher amperage adapter, preferably closer to 10A if you want to run everything off of one single adapter. I use the one linked below and a few splitters in order to power parts of my setup.

this is what I bought. The barrel looks small to me but i used a digital caliper and the female receiver measures 5.8mm so im sure it will fit.

You need a 12v, 10A power supply, these are very common to come across.
