Does this seem like the right fix?

I've been getting fairly random cases where my whole PC freezes up - screen freezes, cannot cycle CAPS Lock, etc.  Only fix is a hard reboot.  Seems like it does it most often while heavy gaming, but it has happened during light usage and even while the PC was idling after a reboot.  I did find some kernel-power (event ID 41) entries in the event log, so I'm suspecting the PSU may be failing.  Temps look OK in hardware monitor - occasionally bumping 80c on the CPU and GPU, but mobo, RAM and SSDs were all reporting a high of 30c.  I did unplug everything and verified good airflow - fans still spinning on case and PSU, so I think next step is to buy a new PSU.

 

I'm currently running a mildly overclocked i9-9900k on a 120mm AIO water cooler, Nvidia 2080, 2x16GB DDR4 3200MHz, 1 NVMe boot drive, 1 SATA SSD, 1 7200RPM storage drive in a very large case (longer than average cable runs) and 4 case fans.  I push 3x 4k monitors and generally multi-box WoW - run 5 copies of the game at the same time.  So my system is running 90% utilization on GPU and CPU for several hours a day.  

 

This case & PSU started life as some cyberpowerPC special some years ago, but motherboard, CPU, GPU and drives have all since been upgraded.  PSU is probably 4 years old.  I don't recall the brand when I took it apart, but it wasn't anything I've heard of in 25 years of building PC's.  What did surprise me was that it's listed as an 80+ bronze 800w PSU, but it seemed much smaller than I was expecting.  

 

I would have guessed 700w would be sufficient, but it seems odd to swap out a 800w PSU that's not delivering enough power with lower wattage unit.  Can someone check my math please?

 

I'm looking at replacing the PSU with a Seasonic FOCUS 750 Gold SSR-750FM 750W 80+ Gold, which seems reasonable for $108 currently, but I'd be open for suggestions.

Doesn't sound like a PSU issue.

Hmm, should I take this over to the troubleshooting forum, or do you have some suggestions on what I should look at next?  I thought the Kernel Power failures indicated PSU, but that's why I'm asking for a 2nd opinion.
