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.

The official Raspberry Pi documentation states that all models of the RPi 3 series need at least 2.5Amps, it use to work OK when we didn't have any form of cpu frequency scaling as the device was locked to 600mhz.
RPi official docs for their devices: https://www.raspberrypi.org/documentation/faqs/#pi-power

¯_(ツ)_/¯
I have no idea what OSMC is let alone what it does, what kernel they have or any number of tens of thousands of options that might make a difference between Fedora and what ever OSMC is. Unfortunately if it's not to the guidance of the Raspberry Pi foundation we just don't have the resources to be able to test and verify it.
The requirements of the RPi3 around power supplies and the problems it causes if you don't have the right one are well documented, it's the number one issue I see, and also for example see even the comment here [1] under the Powering the Board section of a completely different device.

From what I can see on the Raspberry Pi web pages they require a 2.5A power supply.
That would seem to indicate that while you may have been lucky getting one working on a 2A PSU it isn't supported and thus unlikely anything that can be solved by changing anything in Fedora.
