Hello Ralston and thank you for stopping by on my post
What make and model PSUs'?
EVGA SuperNOVA
850 & 1000 T2, 80+ TITANIUM 1000W, Fully Modular, EVGA ECO Mode
If modular, be sure that you did not mix the cables between the two PSUs. Only use the cables that came with the installed PSU. Do not mix cables. I been using the cables from 850 and 1000 since they look the same
Make and model monitors - how connected (DVI, HDMI, DP)? 2 DP and 1 HDMI 2 Monitors are Dell S2417DG and a Elecrow 10.1 Inch Raspberry Pi Screen 1920x1080p HDMI VGA Portable Monitor
What game(s) cause the random black screens? every game
And you are or have done some crypto mining - correct? no
Are all power and screen savers disabled? Yes
Have you tried reinstalling the GPU drivers and (if applicable) any monitor drivers as well. Yes
