pc with gtx 970 shutting down when playing game

[Gatis X]

Hello! I'm having a problem with my new budget build. Actually several problems. First, it shuts down, when I'm a few minutes in game. My GPU is Palit geforce gtx 970 jetstream, This is actually the 2nd GPU I try, the first was Gigabyte radeon r9 290, but it made my pc to restart constantly. I was thinking that it might be PSU (I have 600W Corsair CX600), but gtx 970 requires only 500W. Could the PSU be faulty? Another symptom I experience is that the monitor receives signal only every other time I tur the pc on. The rest of the 50 % it just shows "no signal". In those "no signal" situations motherboard does not make the normal single beep, but several beeps, maybe this info is of some use?

Pc also gets a bit too loud when working for a longer time. I measured GPU temperatures, it starts off with 39 degrees Celsium, when I started the game (Far Cry 4) it was 72, then it dropped to 64. After that it shuts down. Fans are running fine when it goes above 60.

Another wird thing is that my 24 pin cable does not sit very well in the motherboard, I pushed it really hard (there is almost no gap now), but I did not hear any click or something. Maybe there are some power exchange problems?
Thanks in advance!

Rest of my specs:
ASRock 980DE3/U3S3
AMD FX-6300
8 GB RAM

What are your CPU temps reading right before it shuts down? It might be a PSU issue, but then it could also be a overheating shut down (but that does not really explain the 50% good starts)?

I think it could be your Power source. Not that it is broken, but that it is not supplying enough power to your system when you put it under full load. Your card may be requiring less power when it idles, but will require more power when under load. That being said, you will never use more than the 500W it needs. On the other hand, your other hardware (CPU,RAM,MOBO) all require power too. So you could be exceeding the 600 limit.

If this isn't the issue. Run program to check the temps of your major hardware. If it gets too high, make sure your fans are unblocked and that your card isn't covered in frivolous wires.

Yeah also don't trust those CX series power supplies...

Try reseting the BIOS and then flashing with the latest version if that doesnt work .

Its a very budget board with an older chipset and a confusing name
