Question about different Pro models' PSUs

I’ve had a PS4 Pro whose PSU has now failed on me three times, and I’m not interested in paying to have it repaired a third time (it’s never been in warranty when it failed) so I’m probably going to either replace it outright or downgrade to a PS4 Slim. The question I have is about the power supply in the various newer models, like the 7115B and 7215B, as I believe the power supply is different with each iteration (it definitely is with the 7215B), but I’m curious if these changes would meaningfully have a lower chance of problems due to power surges and the like; the electricity where I am isn’t great and could be exacerbating the problem, however I have multiple other consoles and devices with no issues.
