Triggering OPP twice, and then having the PSU explode under 60% load is unacceptable. OPP isn't just there to protect the device or the hardware it is powering from itself, it's there to prevent complete system destruction in the event of an external based power surge too.
So best case scenario with this PSU is that I have a PC that very rarely goes over 60% load. Over the typical 2-5 year lifespan of a PC depending on its main purpose in life, you can absolutely expect more than one power surge to have triggered OPP on that PSU simply due to regular usage. So, after one too many blackouts after a lightning strike, this PSU would be liable to explode, even in the most seemingly mundane circumstances such as a Point of Sale system in a shop.

Companies can make mistakes sure, but after having been warned over and over, and presented with evidence, at what point does something become malice? Especially when it has the potential to burn your whole house down...? Also, a 30 series card can easily spike above the opp trigger point for extended periods of time no problem, as far as real world goes

Tell me which gamer will ever use more than 650 watts, even a 3090 and 5900x/5950x / 11900k both gpu and cpu oc-ed dont reach more than 600-650 watts while hardcore gaming at 4k and ultra and put like 1 kilowat on this psu xD
ps : i am not defending gigabyte , it's just dumb to put 1000 watts on a 750w psu and not expecting it to blow xD

By now you really ought to get an independent research institute to do the testing to duplicate the problem.
The fact that the manufacturer doesn't seem to respond kindly to your findings, maybe they'll be more inclined to listen to scientists... tho I kind of doubt it by now.
Getting the test funded might be a fundraising project.

I find DC Electronic Load argument especially funny because I would expect things to WORK with synthetic load and then blow up with real load due to unforeseen circumstances.
Oh, and I do embedded stuff - from schematics to PCB design for a living for more than 10 years right now so maybe it's just me, what the hell do I know...

Simple
01:20 It is no longer a protection, if in order to prevent an explosion, you pre-emptively explode it! Brilliant, laughed so hard I accidentally emptied the contents of the tea in my mouth all over my monitor!!!!! Good news - its hasn't exploded (thanks Samsung), bad news, i may need a new monitor now!!!

If your test equipment is remotely controllable (GPIB or whatever), consider automating the testing, and publishing the scripts. That would 1) make the testing more repeatable, and 2) show that there's nothing hidden up your sleeves.

O is for Over, P is for power.
Scratch your temple.
The last P... well... that's not that simple
It's something Gigabyte likes to call protection.
Six little letters (MOSFET) that are burning here.

I wonder if this is happening with the evga 1000w psu. My pc will randomly cutoff while playing a game. The pc is brand new, it's not dirty and it doesn't seem like it is a overheating issue.

Gigabyte would probably want to see you it unpacking with proof that it is genuine new and unused and then MAYBEE but probably not would step back.. edit: what is blown's cap manufacturer???????
