Question Possible Overheating or Failure With Power Supply

[CrispyCreme90]

I've been having complete PC crashes with no reboot while gaming after 5-10 minutes of gaming on my rig. Surfing the web and streaming video is fine and there aren't any hiccups there.

It first happened shortly after I smelled a burning smell which I thought was coming from the oven (I was cooking at the time) but later found out it was coming from my PC. I did some research and it seems most likely the PSU is failing or failed and is overheating.

I've run a few tests while underclocking the gpu and cpu in MSI Afterburner and BIOS respectively.
With FurMark it crashed in less than 5 minutes at around 80-85 degrees Celsius.

Most of my rig is pretty old except the gpu.
i5 3570k 3.4 GHz
Hyper 212 EVO Cooler
Gigabyte GA Z77X UD3H
8 GB 1333 MHz Corsair DDR3
EVGA SC 1060 6GB
Corsair CX 600 Watt Power Supply

Before I shell out some money for a new part I'd like to confirm whether it is actually the PSU or maybe the graphics card.

Ok so I opened up the Power Supply and there was a loose piece. Idk what it was but it was like 3 pronged and black and it looked like part of it had melted...

Yeah a new power supply is definitely what I need.

Thanks again for the help guys!

Yea i wouldnt use that psu untill you get a new one.

The 2 i linked above would be good replacements.
