If I have corsair HX850 PSUs for my miners should I immidietly change them or should I wait for official info?
I'd personally change bro. After their reset they supply peak current without ramping for approx 30 seconds is what I understood. That pops the cap, and so far it's the PSU that is most likely to cause this issue. Most other PSU's once reset gradually ramp current.
This is an alarming issue and needs to be addressed by KNC with an official announcement.
Seasonic manufactures the higher quality PSUs for Corsair and MANY other vendors. The HX series is one of them. Seasonic is considered the premier maker of PSUs by many PC enthusiasts. So it's very surprising that their PSUs are possibly causing such a horrible problem.
Here's a comprehensive and current list of who makes what in the PSU market.
