Corsair no, not safe to keep running near max.
I have had EVGA 1300 units running @ close to 92% rated for years now with no issues.
Corsair I will not run above 75%. Just have not had good luck with them in PCs or in mining.
I would not take this as gospel by any means. Corsair is a quality company, IMO; what sort of information are you working with besides anecdotal experiences to come to that conclusion? I can understand having a personal preference, but this seems misleading in the worst way.
You are overdue for a failure with your EVGA with the way you run it and I hope you don't then assume EVGA is a bad company, too. I wouldn't run anything above 75%, because I like some equipment to last and I treat it with some respect.
they all break when pushed hard.

I have yet to kill about 15 corsairs but I have since learned and run them more gentle.
