So all through November I've had an issue with the amount of power the GPU can get. This started suddenly during a game of overwatch when the card suddenly clocked down to 700MHz rather than it's 1380MHz that is should of been a. This as you could imagine caused very poor frame rate. :( My first thoughts were Drivers or PSU. I rolled back the Driver. No change. I changed to another 500W PSU. No change. Tried another card (GTX 650 Ti Boost) Little bit of power issues. At this point I thought. I should RMA the GPU as that was under warranty and now it's back. The issue is still here.

The card can only Draw 165W or 72% of it's TDP. (GTX 970 FTW) Temps never go above 72 degrees. I think it could be the Motherboard not supplying the full 75W that it should but I'm not sure. I am just a tiny bit lost at this point and I'm probs going to get a 600W PSU and a new Mobo just to see if that works but does anyone have any idea what the hell is going on here? Full specs Below...

CPU: Intel I5 4460
GPU: EVGA GTX 970 FTW
Mobo: Asus H81M-Plus
RAM: Adata Gaming series 8GB 1600MHz (X2 4GB)
PSU: Corsair CX500M
HDD's: Seagate Barracuda 2TB and a Hitachi Diskstar 160GB

Nothing stands out as a cause for the GPU getting stuck at 700MHz.
Quick question - does the card lock at 700MHz and stays there when idle? This has been a common problem in more recent nVidia drivers, where the 10 series GPUs had their memory speed locked to 800MHz I believe. Seeing as you have rolled back the drivers, this seems really unlikely.
One thing you could try is going to the nVidia control panel and setting the Overwatch profile power setting to 'maximum performance', which should put the GPU to max speed.
I have had a friend with a faulty motherboard that crashed his computer while playing games, so yes, it could be the motherboard.
If it is not too much trouble, I would suggest you do return it and get a new one, which should fix the problem.

I did try this. Nothing happened. The card after a while managed to sit at 1071MHz and still power throttled. As another side note. EVGA replaced my GTX 970 SC with a GTX 970 FTW. I've just ordered a New PSU but not a new mobo yet. Just trying to eliminate the issue. The New PSU is the Corsair CX550M. The current PSU supplies 38A on the 12V rail. This new one supplies 45A.
