Random Reboots/ PSU Issue

[ProdByGioseph]

Hi, I’ve installed Macos Catalina a couple of days ago and since then my pc started to reboot randomaly. Although it does it quite often I don’t think that it is really rebooting, more or less the pc is turning off and on, as if the power was cut off. I thought about that because i have a 550W power supply with an I7 8700, 16GB of ram, a z370 mobo, 1ssd, 1tb hdd and a GTX750ti that i use only on windows. I also tried to reset my bios and my hackintosh twice, but the issue is still there, I tried to change my power cable but nothing. Please help me, what do you think is the issue? (I left the error that my pc runs into when shutting of and on so you can have a better idea of what’s going on)

I have exactly the same issue, even though my hardware is very different. Catalina worked perfectly fine for a couple of months, then few days ago this issue arose and the system is unusable. I have other disks with Win10 and with Mojave, and both of them show no problem at all, thus I exclude it is due to faulty hardware.
Did you solve the problem?

Well yes, I installed MacOs Mojave and my pc worked like a charm.. unfortunately since I had an incompatible graphics card I went back to Windows after two weeks but other than that my pc works perfectly with macos mojave, no problems at all.

I have exactly the same problem, any solution without going back to Mojave?

Yesterday I managed to solve the issue and my system has been stable since (more than 24 hours at the moment).
For me it was to substitute AptioMemory with OCQuirks. Hopefully that is a viable solution for you too.
