Major usage? Already built? If so, enjoy. Don't like the psu but should be fine.

Just for gaming and maybe some streaming
I have already the Mobo psu cpu
And I’m waiting fractal Design Meshify c case
Also Aio fractal Design Celsius 24

Rams aren’t on QVL of mother board
There are only an other model of the aegis
Not this specifically
Should I will have problems with over lock or something??

One of my friends has the same Mobo+cpu+ram combo and had randomly colored screen and reboot without sigh of booting anything like loading something or what
He has rx570 8gb
What you think might cause that
