Gtx 980ti crashing (requires reboot)

[BIG GREASE]

Pc:
FX 6300
Win 8.1/win 10
32 gb / 8gb ram
3 ssd hd
2 hdd
Cx750m

So problem. PC crashed when gpu load is put onto it. Like benching or gaming. Crashes after 10~ so minutes.

What I've attempted.
Testing gpu in intel machine with windows 10 = pass flying colors.
Bought another mobo
Reinstalled win 8
Installed win 10
Tried two sets of ram
The psu was out of the Intel machine w/2 980s and oc 6600k= fine
DDU drivers and installed 3 sets of drivers. Some back from Jan 2017

And the weird thing is in the Intel machine furmark 8xmsaa =130 fps
On bad machine = 30~ and choppy on both os's.

It's not hdd/ssd issues
GPU issue with cpu??
Bad cpu maybe??

Q: could the psu be on its way out?
Even though it worked fine with sli 980s and oc 6600k.

The problem is with the amd FX 6300 machine

Believe it or not HDD use little more power. Your PSU meets the required amount but not the efficiency being a bronze unit. Is the FX overclocked ? Being a bronze unit over time ware and tear got to it
