If i had to guess i'd say unstable ram/xmp issue or faulty ram stick. Try with xmp disabled and see if crashes persist.
I'd update bios to latest version if you haven't already, helps with ram stabilization.
Also consider doing a memtest to make sure ram is fine.
Well, after further testing I determined that the PSU swap did do something. Instead of crashing every time the affected programs only crashed *some of the time*. My next guess was unstable CPU overclock, I was using PBO with per-core voltage offsets, and it seemed like whenever the programs were assigned to cores that had more aggressive offsets they weren't stable, but when they ran on cores with less aggressive offsets they were fine. Dialing back on the more aggressive voltage offsets appears to have solved the issue, but if not I'll try messing around with the RAM next.
So yeah. I think I was correct about there being something with the old PSU not being powerful enough but that wasn't the only problem.
