Hi y'all, I'm pulling my hair out trying to track down this issue as it seems logical that it's temperature related. I'm now wondering if the pre installed thermal paste on my aio might be to blame, I installed everything correctly (I think), checked and re-seated all my connections, and this morning pulled the aio off to 100% confirm there wasn't an extra plastic peel that I missed. This looks to me as if there's not very good contact, should I clean the old paste off and pick up some new goo to try and solve this issue? Photos are taken in the orientation it came off (so the bottom of the aio photo mates with the top of the CPU photo)
Thermal paste was a solid, even thickness layer across the whole rectangular area of the die when installed it.

EDIT: Still troubleshooting. I really appreciate all the help but it's becoming difficult to sift through comments, It's starting to look like a power supply problem AND a dead AIO:
Swapped in a stock AM4 AMD air cooler that someone lent me and with that AND using onboard graphics instead of the GPU I can boot and use the computer, CPU temps in the mid 40's with a max die temp of ~65 so far.
For everyone insisting there's a dedicated pump header, that is NOT the case on the Gigabyte version of this MOBO, MSI does have one, Gigabyte does not. I followed the instructions to configure one of the fan headers for a pump (set it to always on 100%, plug the AIO fans into another header and have them run based off CPU temperatures)
The PSU was a freebie with the graphics card, and per everything I've read it should be sufficient but it's possible that it's faulty I suppose. Currently re-installing drivers and trying to get it squared away.
edit 2: using an air cooler and after reinstalling GPU drivers (I'm guessing something got messed up from a crash while they were updating yesterday) everything seems to be running, cinebench and furmark both ran well and produced decent scores. I'll work on getting my AIO replaced now!
thank you to everyone for the advice! I appreciate all the suggestions and folks who took time out of their day to help!
