The GTX970 requires a minimum PSU wattage of 500 watts while your FX 9590 TDP is 220 Watts.
The maximum Operating Temperature of your Processor is 57C. So if the temperatures don't go above 57C you are within Operating temperatures.
The Power consumption of the FX 9590 at full load using OCCT is 350 Watts according to this Tech Site review: 2014 Test Setup and System Benchmarks - AMD’s 5 GHz Turbo CPU in Retail: The FX-9590 and ASRock 990F...
So it is possible under very heavy CPU Loads and GPU Loads it may come near or pass your PSU ability to give proper power. That is where OCCT PSU Test will prove by running it.
I would suggest you restore your FX9590 back to its default settings and then download OCCT.
OCCT is a free diagnostic that checks PSU by stressing it. This is the only Diagnostic software that checks and stresses the PSU.
Download the OCCT. Run the CPU Stress test first and see if it crashes or passes after about 45 - 1 hour of testing. During the Testing you can keep an eye on the PSU outputs 3.3/5.0/12 Vdc. and the CPU's load and temperatures and other pertinent info.
If it crashes try to find out what the PSU outputs were. They should be within 5% tolerance of each reference voltages. Also check to see if it crashed due to overheating which might indicate something is wrong with your AIO CPU Cooler.
IF the CPU Stress test passes now run the PSU Stress test. This test basically runs both the CPU and GPU Stress tests at the same time putting maximum stress on the PSU.
While running keep an eye on the PSU's Outputs again and on temperatures and loads. If it crashes immediately and shuts down you need to look at the test results to see why it crashed. Did it crash due to Overheating or PSU voltages being out of tolerances?
If you don't want to use OCCT you can download one of the free Hardware Monitoring software that shows PSU outputs. Run a game and check the Monitoring software for any unusual temperatures or voltages.
