He should Sue them for $$$$ .
and get laughed at?
There is zero proof (thats acceptable in court) it happened llike he states.
There is a reason data clauses are very rare as its nearly impossible to prove what actually caused it.
The system can easily be abused is why.
whats that? your drives are dying according to SMART? Welp would be such a bad thing to claim my storage drives died due to totally not my own fault but say it was psu by totally not purposefully casuing them to die on purpose to save a ton of $....
Another case example of why people should stop thinking about companies as their friends.
As someone who has used EVGA psu, GPU, & case over years & has used their support a few times....They are one of the better companies....but mistakes DO happen (doesnt mean its out of spite/ill intent).
Remember the New World killing gpu disaster all those yrs ago? evga replaced all of em (even before the reason was known) while others didn't.
EVGA's gpu stepup was also great for ppl who liked to upgrade frequently. (and they didnt need to do that as financially it was likely not a great profit vs buying entire new gpu)
Companies do want to be your friend (within a limit) as it generates brand loyalty & a repeat customer thus profit. However again PSU covering data is soemthing i'd never do as again it would be way too easy to abuse and lose $ due to bad eggs.
Also let this story remind you: Always read your documentation for anything that involves electricity....its entirely common and known "refreshes" happen using same SKU/part number where stuff changes (remember the shingled hdd lawsuit or the ssd, which i forget brand, that used lower quality controller randomly and was worse performing?)
This was a case of user error, company mishap clashed and caused damage. Sucks but it happen.
