Unexpected shutdowns and bad performance

[MbV93]

Hey forum, I come to you with a problem.

 

I've known that something is wrong with my computer for a while now. I started to notice that none of the games I play are smooth and I don't get the performance I should be getting, I get horrible drops in framerate like being in the 60s and suddenly bam! 40, even in League of Legends, also my gpu load is stupidly low playing BF4. Mantle refuses to work at all, it's a stutter fest, I even upgraded to Windows 8.1 to see if that would fix the problem, nope it did not.

Now my computer has been shutting down when in load, at first I thought it was temps obviously but yesterday I made a little experiment, opened up a bunch of programs and games like BF4, Unigine Valley, a ton of tabs in firefox, spotify, steam, origin etc... and monitored temps with hardware monitor. none of them high enough for shutting down:

CPU 50°C

GPU 72°C

HDD 42°C

Temperature #1 57°C

Temperature #2 75°C

Temperature #3 54°C

 

But it did shutdown after a little while. I should also mention that my FX 6300 doesn't overclock past 4GHz, It needs a stupidly high voltage, with Turbo enabled and all cores at 3.8 it's fluctuating between 1.41v and 1.43v so I'm thinking it could be my power supply dying, or something is really wrong with the motherboard.

My system:

CPU: FX 6300

Motherboard: MSI 970A-G46

RAM: 2 sticks of Kingston blu 4GB 1600MHz

HDD: WD Caviar Blue 500GB

GPU: R9 270X Toxic

PSU: KingWin ABT-650MM

 

What could it be?

That is kind of a cheapo PSU. Wouldn't be surprised if that.

Can't be software because you already upgraded windows.

Like it has already been said, I too have a gut feeling that it is your PSU. There's a possibility that it isn't, but I would still recommend you get a better PSU as soon as you are able. Johnnyguru seems to have the best, most thorough reviews around. EVGA has been knocking it out of the park with their G2 line lately...
