Linear power supply 12V/ 3A Too Low?

I’ll be getting an ethernet switch the runs on 12V. The Linear power supply has two power outlets.

My question is simply can the Roon Nucleus run on the 12V/3A PSU? 12V time 3A equals 36W.

I think I remember reading somewhere that the Nucleus needs 5A???

TIA

I don’t own a Nucleus, but it looks like the stock power supply is 19v 60 watts.

You might try posting in the Nucleus Support thread and open a ticket. (pictured)
