Issue after installing GTX970

So, before I explain my problem, here are my specs:

Intel i5 2500k currently running stock
Cooler Master Hyper 212+
Gigabyte GA-Z68x-UD3H-B3
4x4GB Corsair Vengeance DDR3
OCZ OCZ600SXS2 600w psu
120GB Kingston SSD, 640GB WD Black HDD, Sata DVD drive

Previous Video card: Gigabyte Windforce GTX760 2GB
New Video card: Asus Strix GTX970 4GB

So the issue is that after I installed my brand new video card this past friday, whenever I play anything graphically intensive (For example, I loaded up Far Cry 3 to update the in game graphics settings then played for a bit, and I also did the same with Shadow of Mordor and tried the Bright Lord DLC) I can play the game fine for a bit, so far its been anywhere from 10 minutes, to almost an hour. But then the system with just shut off and start back up.

However, when it starts back up, nothing will display, monitor never comes on. I have to turn it off and let it sit for upwards of an hour before it will boot again. Now I thought that it may have been overheating since the fans on the Asus Strix dont turn on until a certain temp. SO I loaded up the Asus software that came with it, manually set the fan to somethign like 70% (which is really loud), and ran Furmark stress test. It will run that for maybe 5 minutes, then it shuts off and restarts, then Im stuck waiting again. So Im lookin for some ideas as to what the problem is. Is my PSU no good? Is it possibly because I dont have an 8 pin power cable running into my motherboard (The 8 pin cable is long enough so I had to run a 4pin extender to it)?

Here is a pic of the internals as they are right now, please excuse the mess ;)

You don't have the 8-pin PCI-E power cable connected to the video card in the picture you posted. The extra power is required for it to operate at spec.

When you say "I dont have an 8 pin power cable running into my motherboard," do you mean the +12V EPS for the CPU? That shouldn't be an issue with the CPU running at stock speeds. Don't mix up the EPS and PCI-E power cables.

The inside of you computer looks like the first time I modified my first eMachines PC 16 years ago :p.
 
With the EPS cable running underneath the video card, are you sure that it's making good consistent contact in the PCI-E slot? Only other thing I can thing of is that the STRIX droops a bit in my case, so maybe if you try to rig up some way to give it extra support from the top. It's hard to tell if this is happening in your case with the angle of the picture.
 
At work right now, I will confirm its making a good connection when I get home. Ill see if I can prop it up. I did notice it drooping a bit when I was taking the picture.
 
That psu is probably a pos, could be that its overheating and has to cool before it can work correctly again and supply power to the video card. Do you have another psu you can try? Do you know the temps of the graphics card before it shuts down?

^^ This. PSU is the issue.
 
When I ran the Furmark stress test with the fan at 70% the temp never hit 50 celcius before it shut off. So I figured the card wasnt overheating at 48 or 49 celcius. My guess was the PSU as well even though I had no issues with it while running the gtx760.

^^^ agreed. probably the PSU or related cabeling. you got another PCI-E power to try? try it. Ether way probably better to just swap the power supply to be safe once you confirm that is the issue.
 
Your PSU wasn't even good when it was new. Considering the recent HardOCP article showing that even high quality PSUs can degrade badly over 5+ years, that PSU more than likely can't provide the full 450W (FYI, that PSU was only capable of about 450W to 500W of safe power). So I would not be surprised that it's your problem. Go for the Seasonic SSR-550RM or Seasonic SSR-650RM if it's only $10 more.
