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.

Yep.

I like how KNC have a situation with Corsair PSU's and they ask a guy from GE!

Does anyone know any Corsair engineers? BTC whip-round and we fly him to Sweden tomorrow to join the "discussion" Grin

The "guy from GE" is the VRM expert/engineer....I think he would know how to use an oscilloscope.

So, the GE engineer, I think, has shown conditions that can cause the blown capacitor. If it is repeatable, then just changing that capacitor or one of the others in that row if blown, can allow the board to be used again for testing. If the conditions genuinely can produce a repeatable fault, I would like the same test done but with a motherboard plugged into the motherboard connector. This would show that the jumper isn't bypassing some voltage drain necessary for the supply to wake up properly.
