[fedora-arm] Fedora Server need more Power than OSMC

I have two raspberry 3+.
I installed on one of them OSMC and use it as Media Center in my home. Power PSU is 5V 2A. and it works like charm.
I installed on another one Fedora Server 30 and I want to use as a server in my home. Power PSU is 5V 3A. but it has some problem and I am sure will be fixed.
when I change PSU and use 5V 2A for Fedora Server, it boots and after I see some booting messages. Fedora Server reboot and I can not log in to Fedora Server.
Can I find options for normalization of power in Fedora server for work better on Pi 3. by use PSU 5V 2A.
I want to find way my Fedora Server can work by PSU 5V 2A.
