Also im sorry if this partially hijacked the thread but i couldn't think of a better community to come to for an issue like this. Especially if it was the Board its self.
Once i get a chance to RMA the RM850x ill shoot for another OC and post it here, this time with a few screen caps of the temps and results.
You know what, i had a Corsair RM650i, i put in an ASUS graphics card which needed 8-pin PCIe power, and even though it all drew nowhere near the capabilities of the PSU, i suddenly had the PC turn off a few times. I now have a Seasonic Ultra PRIME Platinum and i will avoid Corsair PSUs. I'm not 100% sure it was the PSU, cause i initially ended up throwing out the graphics card instead, but it was a bit too suspicious.

Install the new BIOS 7B12v14. https://www.msi.com/Motherboard/support/MEG-Z390-ACE
Make sure to install the current Killer drivers from here (2.0.1170 at this time), they're newer than those on the MSI site: http://support.killernetworking.com/
Then first of all, run the Win10 memory diagnostic. Should take maybe 20 minutes or so and weeds out basic RAM errors.
Then get Linpack Xtreme: https://www.techpowerup.com/download/linpack-xtreme/
It's by far the best tool to detect instability, reacts even quicker than Prime95 and MUCH quicker than OCCT.
Get CoreTemp: https://www.alcpu.com/CoreTemp/
Open CoreTemp and note the idle temps.
Run Linpack, select 2 (Stress test), 5 (10 GB), set 30 times, press Y to use all threads, and let it do its thing.
Check Core Temp, note the leftmost "Power" number and note the max temps. The Power number should stay well above 100 W, since in the 1.4 BIOS, the Long Duration Power Limit is set to 4096 Watts. If you want your CPU to stay within Intel spec and you don't want to OC, go to CPU Features in the BIOS (way at the bottom of OC) and enter 95, like so:
You will then see the power draw go down to the 95W TDP after about half a minute, like so:
Also clearly visible from the fan RPMs, which are depending on the CPU temperature, which depends on power draw.
You can also try around with "CPU Lite Load". Default is 11, to be able to run the worst silicone (highest VCore required in testing) without stability issues. But most CPUs have better silicone quality and you can go lower, decreasing power draw. Instability can easily be tested in Linpack Xtreme. For me it was unstable at CPU Lite Load 3, so i went two higher for headroom, using 5 now, rock stable and over 10W less power draw. You can also set the rest of the settings like on that image.
Under OC, disable Enhanced Turbo for now, see here,
I took the photos with BIOS 1.2 a while back, but it's all true for 1.4 too.
If all that is stable in Linpack, we'll see what we do next.
