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.
Which was why I started the post (part that you didn't quote) with "Dave's opinions"
None of us can really speak to this beyond our own experiences and what we see here.
Would it have been better if instead of "opinion" I had said, in my limited testing of less then 100 units in mining EVGA and seasonic
tend to seem to be able to take more abuse then corsair.
And in my real job of IT work, with countless power supply replacements over the last 2 decades. The generic / OEM power supply units have the biggest pile in the recycling box with corsair running a distant second but still many more then any other brand.
Once again, nothing I can prove that matters. Is corsair #2 in dead units because they are #1 in replacement power supplies so by nature I am going to see more?
I don't know.
All you and I and probably most people here can give is opinion.
Unless you want to go out and get a few 1000 of each brand and run them at 90+% in a controlled environment for years and keep track of how long they last. Because in test sample size less then that, it's all just opinion....
What I can *also* say is that in very limited times I have done the RMA myself, EVGA is easier to deal with then anyone else. They are also the slowest.
