Installed a new PSU, getting crazy temps.

Hi guys, so I recently got an AX860 PSU. It upgraded my old hx1050. I was putting it into my system, when I noticed my GTX 770 had a fair amount of sag. So I supported it with some fishing line to the top of my case, and it did the trick. No more sag, and this PSU seems to be running fine.

The problems started when I lauched battlefield 3. I can get to the spawn screen, but 3-5 seconds later my system crashes. I had to restart.

Now, I figured this was my power supply, so I did some further testing. I launched HWMonitor, and launched a program to stress out my GPU (DogeCoin miner). The results surprised me. My temps were going from 30 degrees C (normal) to 90 degrees C in 2-3 seconds. My system was crashing because of these temperatures.

Please watch this video, it shows what is happening. Please set the quality to 720p. http://youtu.be/QIv3ir0SXRc

These temperatures ARE NOT normal. I have had the gtx 770 for months. Normally it takes 2-3 minutes to get that hot. I have never had temps above 70 degrees before.

So, either something I did with the fishing line to support my GPU did this, or it is something to do with my new PSU configuration.

Can a PSU cause this? Its a brand new AX860.

Thanks

sounds liek when you were supporting the circuit board, you allowed the heatsink to peel away from the board. now it should be tightly enough connected to avoid that... proving that you have the problem is the issue. So...

I just removed the fishing line, and it completely fixed the problem... wtf? Can simply fixing a little sag cause poor contact?

Should I RMA this card? The fishing line was barely supporting it... it moved the end of the card up just a few mm.

Edit: okay...wow. So with my GPU stresser running, and the card UNsupported, I am getting normal temps. When I gently push up on the card with my finger to support it, the temps shoot up to 90 degrees.

So i would accept the sag, or support from underneath, i.e. push on the heatsink.
