Worker contantly going offline

Hi everyone,

I have a problem where worker keeps getting offline to often. At first I had 5x3060 ti and worker went offline once in about two days or so. Recently I added a 3080 card and now it keeps going offline 3-4 times a day. Temperatures are normal, Mhs/s is stable. PSU is LC Power 1650w. Whole rig usese 1000w. Does anyone know what could cause this? Any experience whatsoever similar to this? Drivers are up to date, Hive OS on the latest available version. Can anyone tell me which logs to look at and try to catch any errors prior worker going offline that may be causing this behavior?
