First I'll let my specs here to people who will kindly try help me with my situation, or at least enlighten me.
Mobo: ASRock GS4-N68 FX
CPU: AMD FX 8350 4.0GHz stock cooler
GPU: Sapphire R9 280x vapor X tri 3GB
Memory: G.Skill Ripjaws 4GBx2 1600Mhz
PSU: EVGA 650 GQ
Old Mobo: Asus M5A97 LE R2.0
Old PSU: Corsair CX750
Ok, so here I go again try to explain my situation.
Around six months ago I believe a power surge fried my mobo(yeah, I found a burnt hole near the VRM some days later), it was a Asus M5a97 LE R2.0, but it was still kinda working when using the pc normally, and it was shutting down the pc while gaming, black screen, no BSOD, error 41 on windows event viewer.
Assuming it was the mobo, I bought a crappy ASrock GS4-N68 FX just to continue my job and play normally for a little while. The pc turned back to normal for around one month, I was even able to finish Dark Souls 3 at the time, but then it started all over again.
I did every single kind of test trying to debug this, I was afraid it was the VGA of course, it was the most expensive part of the rig, but it turned out that it wasn't it.
I noticed some stability when I tried another PSU, it was a XFX 850W Black edtion(pretty neat PSU from a friend of mine), still there was no shut down, but the performance was bad af while gaming, I discovered that was thermal throttle messing with it, but I'll talk about that later.
So, my new thoughts were: I need to buy a decent PSU that handles my rig. I did the math and it consumed about 530W, my old PSU was a 750W, naturally it would handle, but it wasn't.
After some researches, I decided to bought a EVGA 650 GQ, which you can see it is a pretty fine PSU that can handle this. But this week when I bought it, the same thing kept happening.
After a existencial crisis, I decided to eliminate every possibilty it was the PSU, so I started reviewing some things. First thing was the processor temperatures, and it turned out it was really bad, around 75c idle, and it was funny because it wasn't showing that before, don't know why. Still, reapplied the thermal paste, idle temperature dropped to around 45, 50c, and 70c on load.
Here in Brazil this temperatures are kinda normal, even with a modest overclock of 4,5Ghz, and a corsair watercooler, people get aroung 65c with full load on hot days, not my case of course, but it's still a kind of example.
When I activate thermal throttle, the pc can run some games like Overwatch and CSGO, but that hard fps drop happens almost every time, turning it very annoying. But when I deactivate it, games run like a charm, yeah, but it shuts down after a minute or two.
It's kind of frustrating believing it is just a thermal problem, because since I bought this pc my temps were running like that with the old MoBo.
So, I really can't think of nothing but to believe there's something with my CPU, It's strange that with the XFX PSU, everything was at place, I mean, I know it was a 850W PSU, but still, my other two PSUs are more than capable of handling this configuration, and I believe things don't normally change their load, also known as impedance, from nowhere.
Does anyone have experiences with something like this, or have any thoughts? I'd be very appreciated if someone give me a hand. If you need something like Core Voltages, graphs and stuff like that, just ask and I'll post it right away. Thanks in advance guys!
