It seems to at least not be crashing however still in testing phase..
Also problem has not dissapeared entirely...
I got following today:

However like i said this didn't take down server....
Also my CPU temperature has dropped with new PSU! Suppose it has fan bottom actually extracts heat....
CPU temp now 42 degrees celcuis...
