Question Crashing with two different GPUs

I've been experiencing consistent crashes with two different RTX 2080 GPUs over the course of two months. I initially purchased an MSI RTX 2080 Super that consistently caused my entire desktop to lockup and the gpu would just power off at completely random points. It could be while sitting idle at the desktop with nothing running or while playing a game. Suspecting it was the card, I just had it refunded and later on purchased an Asus ROG Strix RTX 2080 Super. After 3 days of running this card, I've experienced frequent crashes in games, however nothing that would lock up the entire PC like my previous card did.
When I monitor the card during the crashes, the temps are fine on both the gpu and cpu. I've spent days trying to troubleshoot as much as I could. I've reinstalled drivers with DDU, reseated the card, tried playing games on different drives, updated bios, reinstalled windows, made sure power plans were on maximum performance etc. Nothing seems to work.
Prior to upgrading, I've had a GTX 1080 that has run absolutely fine with no crashes for years on this same build. I've even ran the GTX 1080 again after removing the RTX 2080 and everything runs fine without issue.
Specs:
  • i7 8700k, not overclocked
  • MSI z370 Gaming Pro Carbon AC
  • Trident Z 32GB ram DDR4 3200mhz
  • Asus ROG Strix RTX 2080 Super
  • EVGA Supernova 750 G2, 750w power supply
I'm not sure if its the power supply that's causing the issue. I've checked all the connections to make sure everything is tight and in the correct place. The RTX 2080 Super requires two power cables and I've made sure those connections were secure. Its just that I've been having issues with these two RTX cards and I'm wondering if my PSU is having problems supplying adequate power to them. I do notice that when I get stuttering that precedes the crashes, the gpu usage tends to fluctuate 90% of the time prior to the crash. All the while my GTX 1080 runs absolutely fine when I reinsert that. I don't know the probability of me getting two defective cards, so I'm just assuming its something to do with the hardware on my end.
In any event, I'd greatly appreciate any advice!
*Also wanted to add that the windows reliability monitor and event viewer point toward the crashes as nvlddmkm and hardware errors.

Did you happen to uninstall drivers and installing them back after removing the GTX 1080?
You should remove drivers, power off PC, install new GPU then re-install drivers.
Yeah, I've made sure to remove the drivers with DDU and reinstall everything manually every time I've tested. No changes unfortunately.
 
How old is that PSU?
I have installed a Supernova 650 G2, 650w with similar components and it worked without issues.I would try
I would point to PSU if it only crashed while the system was at full load but it happens also when idle.
I would try another PSU, since even very good components could fail or stop delivering withing specs.

I bought the PSU new about a year ago. Yeah, I'm gonna see if I can get my hands on another psu. I suspected either the psu or motherboard, but all the troubleshooting is driving me insane lol!
