ok i see you have the cx550 non modular and so cant try a new cable. download hwinfo and check the 12v supply from your gpu and see what the 12v reading drops to under load. check the minimum voltage recorded on hwinfo by looking at the minimum tab
Edit: yes to both cooler and case![]()
I'm having exactly the same issue on my PC so i'm interested to see if the new CPU cooler works.
I have intel i7 4790K (not OC), KFA2 2070S (not OC), 16Gb corsair vengeance LP ram @ 1600MHz, GA-H81M-S2H mobo, Kraken M22 CPU cooler and a Corsair SF750 small form PSU.
I've also got Steelseries Arctic Pro wired headset perma plugged in as well as a gaming mouse and keyboard. Outputting to a Samsung CF791 34" monitor.
I've tried reseating all the power cables and swapping the cables supplying the GPU. Using Afterburner to log temps doesn't seem to show any extremes of temperature in either the CPU or GPU when the crashes happen.
New PSU?
My case is a Coolermaster MasterCase MC500M
Also I sent the GPU back to be tested and no problems apparently although I didn't get the problem with my old GTX 960 or a second hand RX480.
I've also done the drivers thing twice.

didn't realise there was more than 1! I was checking the +12V in the section about the motherboardwhich 12v voltage did you check?
So I just did a GPU stress test. It got around 1/4 through, reaching 86ºc, then the screen went black. It is worth noting that I can hear my music playing and things working as normal, my screen just becomes unresponsive.
Did that and got a message that said:the volmgr is a concern as that maybe hdd/ssd having bad sectors. could be causing the issue. try running cmd as admin then copy and paste chkdsk /f. Then restart and copy and paste this into cmd admin SFC/ scannow and see if it finds any errors. i had an nvme drive go bad randomly that did the same is your system is.
