@Fimbulwinter04 hey man, your GPU need an PSU from minimal 550 watt !
If ya run 600 watt PSU then i think you got a little low Wattage for the whole system !!!
Also youre CPU is eating easy 60 til 100 watt power, and more !
Dont forget the drives, Leds , AIO and fans ya got installed need also WATTAGE to run properly to.
Youre pushing youre PSU to the max and even beyound the max.
Its possible a security get triggered in youre PSU to shut down for protection.
This protect only youre PSU, but as soon system powers down, CPU and GPU stops with cooling ,
and could get damaged as soon there is no airflow , running AIO pump !!!!!!!!!!!! <-- start up system ASAP !!!!!!
Or its even possible youre total system (motherboard) gets not enough Wattage, gets unstable , why some errors occure (hardware errors) and shutdown system.
Ya need at least 850 watt PSU , or even higher ,
(higher is better -->> it will also use less power then and grants better stability, it also generate less heat).
It all depends on the hardware ya got installed and/or
connected (headphone, keyboard , mouse , dongles , external drives ect ect ect)
Also make sure ya cooling is ok, use HARDWAREINFO64 to check temps, and also keep and eye at the Wattage thats is been used by youre system when ya run software, bf2042 for example.
Remember, sometimes there are peaks of Wattage needed that go beyound youre 600Watt psu 😉
Cheers
PS pushing youre PSU all the time to the max and/or beyound it could damage/break youre PSU - if it isnt already damaged 😉
When ya push youre PSU all the time to the max it will also generate more HEAT
Make sure PSU take in air from outside the case, and not use the air thats already in youre case (thats already wam)
keep us uptodate please !
