The problem started few months ago but its getting worse and worse. Sometimes when I play some games my PC just turns off. I've tried to fix it myself, done some testing. It turned out that when I decreased GPUs overclocking it worked fine for a while. However, problem returned after some time. I've restored GPUs overclocking values to defaults and it worked fine for a while again. Now I got the problem again.
I've done some testing. Running Prime95 - everythings fine. Running furmark - PC turns off instantly! My friend told me that it might be RAMs and I should switch their positions. Tried it, same problem. Don't think its GPU overheating as PC just turns off instantly when trying furmark, there is no time for it to overheat.
When I set core voltage and power limit to minimum in MSI afterburner I can run furmark but I don't think its the way of fixing this problem, it might return again.
What could cause such problems? My guess is its faulty PSU but i'm not sure. Do you think 550W PSU is enough for my setup or I should buy more powerful one?
My setup is as below:
