Bad Power Supply?

[Thomasthegreat]

Hello,
So lately when I have been playing Arma 3 I will be getting fantastic frames (80-90 single player) for about 30-45 minutes only to experience a drop to about 5 out of nowhere with no recovery forcing me to quit the game. At first I suspected thermal throttling, but my CPU only reaches a max temperature of 53C during stress tests, and my GPU sits at roughly 60C with fans at only 50%. I then launched the game without mods only to have the same issue. Could my power supply be causing the problem? It is pretty low quality (please don't scold me).

Components:
I5-4590
MSI GTX 970
16 GB Ram
1TB 7500 HD
MSI Z97 MB
PSU: EVGA 500 W1 80+, 500W

I've been meaning to replace my power supply for a long while now due to the fact that I first purchased it for a barebones build, but I would first like to know for sure if it is what is causing the issue.

Many Thanks,

Thomas

I would replace the very poor unstable power supply , your nice build deserves a high quality 550W.

PSU needs replaced, but highly doubtful it's causing your problems. Sounds more like software related issue to me. The fact that you have the capability to quit the game tells me it's not a PSU-related freeze but sounds software/driver related.
