Hi everyone, this is my rig:

Asus M5A97 R 2.0
EVGA GTX 960 2gb (The problem started when I changed my old HD 7790)
AMD FX 6100 3.1 ghz
16 gb of RAM 1600 mhz ddr3
Bluray optical drive
1 tb hardisk
[strike]cooler master[/strike] THERMAL MASTER cheap case
500 w PSU (came with the case)

The thing is that some years go I had a similar issue that turned out to be cause overheating (I solved it by buying fans), but this time when I log the temps (mobo, cpu, gpu, hd) they all are running within spec (less than 70 for mobo (though very close at 68 one time), less than 60 for proc, less than 80 for GPU.

I'm suspecting that this time is because I'm using more power (gtx 960 TDP is higher than my old card)

What's your opinion folks? should I upgrade my PSU, my cooling solution or both? Can anything else be te problem? How do I trouble shoot the issue?

Thanks in advance.

Those are fine temperatures, they're not overheating. Do you have an extra system to try to GPU in? Also, I'd replace that PSU soon (as fast as you can), as it's.... it's not very good. That may be the problem, have you tried another power supply?

You should just need an upgrade on your PSU, since your GPU is the hottest component in the system. That means the FX-6100 is 69°C and less. Have you checked the CPU/GPU temps when the PC shuts down? Have you set the shutdown to something like 60°C for your CPU?

Upgrade the PSU, that cooler works. But, if you want to bring out the full potential of the 960, upgrade that CPU.

The temperatures posted at AT SHUTDOWN (quoted temp is highest logged temp at shutdown time in 5 different experiments), but the weird thing is that those are normal range temps according to my research for my components. The PSU is branded thermal master and rated 500w

I have a PC parts shop across the street from my job, So I can change the PSU tonight. What kind of PSU should I get? should I worry about not fitting my case (is a standard ATX case) thank you all, you have been very helpful.

Seasonic, Corsair (not CX), or Thermaltake are common and should do the job nicely. I would measure the dimensions of the slot for the PSU (or take in the PSU you have in the case and compare it/ask)

IT WAS THE PSU, I bought a EVGA 430W and it worked like a charm (according to this http://www.tomshardware.com/reviews/power-supply-psu-brands,3762.html it has all I need: Active power factor correctiom and all pasive protections).

Apparently my old PSU was only capable of outputing 20 A in the 12 volt rail, but according to this (http://outervision.com/power-supply-calculator) my setup uses upt to 24 amperes in the 12 volt rail. The new PSU is capable of outputing 34 A. Thanks to you all.
