I’ve Recently upgraded to the 12900k and have been having full system locks, no blue screen just full freezes. I’ve uninstalled iCue, reseated ram and tried without XMP as well as constant temperature monitoring and logging. I was looking for any suggestions on what may cause this. I’ve narrowed it down to the psu not being sufficient. It’s a 750w platinum. 12900 paired with a 3080.(ddr4 on a z690 edge)

These locks only occur during heavy load/while gaming. Halo Infinite would just crash the game but games like War Thunder and Siege would fully lock the system. Temperatures are all nominal. The GPU worked fine with my 9900k. Windows is a fresh install. I’ve ensured bios settings are set properly. At this point I’m highly siding with the fact that I’m pushing my 750w psu too much with the 12900/3080 +4m.2’s,4ssd/hdd’s, 9 fans, 3 rgb/fan hubs.

I work building systems 9-5 but I’m still stumped and too exhausted from work after the day to want to troubleshoot more pc stuff. Though I still want to ask, is there any other potential reason I may be encountering these. Maybe something I can try in the meantime whilst a wait for a new psu?

Edit: Turns out it was the ram. Swapped for some basic ram and system freezes have halted.

Don't be unhappy! That's one of the least expensive components and certainly the least annoying to swap out. Thank the occasionally cruel computing gods that they saw fit to unleash the plague on your RAM and not your GPU.
I’ve already got the rma generated for Corsair, and I’m just using some random dell sticks for now haha! It’s so relieving knowing it’s just the ram.

How did u know?
I initially reseated the cpu and continued having problems. Next I decided to test one stick at a time and continued having freezes. Finally, I swapped out my Corsair ram with some random ram I had in another system and have not encountered any problems since. I’ve got the Corsair ram RMA’d and hopefully won’t have any issues with the next kit
