I have been using a 2011 Dell XPS 8300 for the past 8 years, with periodic upgrades such as the addition of an SSD, a couple GPU upgrades, etc. Recently, though, I was really feeling the slowness of that i5-2400 and I decided it was time for a platform upgrade. I bought a Ryzen 3600, ASRock X570M Pro4, Inland Performance 1TB PCIe 4.0 NVMe, and 16GB (2x8GB) Corsair Vengeance LPX DDR4-3600 CL18. My plan was to use a few components from my existing build for the time being, such as the Dell case (I did a bunch of research to make sure the front panel/USB pinouts were compatible), the Gigabyte GTX 1070 I had put in the Dell a few years back, the Cooler Master Elite V2 550 (a ~485W PSU according to JonnyGuru) I had installed for the first GPU upgrade several years ago, and the SATA SSD and HDD from the Dell as secondary drives.
The last of the parts got here today and I installed everything without any issues. It was running well for about 7 hours while I installed Windows and all my programs, ran a few benchmarks, etc. About an hour ago it started suddenly powering off and restarting. My first instinct was to check the CPU temps, and while idle does seem a bit high (45-55C) it doesn't get too far above 75C during intensive use. I doubt it's a PSU issue, as the Ryzen 3600 actually has a lower TDP than the old i5-2400 and that was the only major change in terms of power draw. I already installed the proper drivers, newest BIOS, etc. which was all working fine for several hours. Event Viewer lists what is happening as "Event ID 41 Kernel-Power" which from what I can tell may point more towards a power issue. Any ideas?
EDIT: After one more occurrence of this during which I was watching HWMonitor closely, I noticed that the CPU temp is spiking like crazy very briefly (from 75-77C under full load to like 89 in a split second and then back down to 77 immediately) which is alarming, but still, shouldn't I be seeing thermal throttling at TjMax as opposed to shutdown (and isnt TjMax 100C)?
