Random reboots under load - PSU or CPU?

Specs:
- 13700K
- RTX 4070 Ti
- Corsair RM750x
- 32GB DDR5
Started getting random reboots during gaming about a week ago. No BSOD, just instant black screen and restart. Happens most often in GPU-intensive games.
Things I've tried:
- Memtest86 - passed 4 runs
- DDU + fresh GPU drivers
- Checked all power connections
- Monitored temps - CPU max 82C, GPU max 76C
I'm thinking it might be a PSU issue since 750W is tight with a 13700K + 4070 Ti combo. Transient spikes could be tripping OCP. Thoughts?
