Glad to see this is only for October of 2019 to March of 2020 I wonder what the process issue was to only effect that batch. Also given the time table they found this and issued recall pretty quick. I have over 40 of these things so good to know they are on top of it. Although recalls are often looked as a bad thing I think how they were willing to do this and let everyone know and identify that it was only some newer batches that they are willing to admit when they messed up. Given it was only recent batches I feel like they must have swapped a part out for a lower cost replacement and found out fast it was not a good idea or perhaps it was a bad part of a supplier that messed up all the recent batches.


It would be cool to see a tear down of the recalled version vs the older ones to see if there is anything noticeably different internally.

When will people learn? Remember the warning thread telling you that corsair was bought out and to avoid their products?

Wow, this all happened in 2017 eh? My last custom PC was in 2010 (socket 775) but I still stopped by OCN every once in a while to see if AMD came up with anything competitive. But man this news totally flew under my radar. Good to know.

good question, since it was blasted everywhere.

maybe y'all were too caught up in the logo change threads instead.

jon gerow (aka jonny guru) works in corsair's psu R&D.

Like I've already said in this thread, the failure is on the PFC diode. There's no risk to damaging the rest of the PC's hardware.

Quote:
Is the capacitor failing?
No. It's from the insulator pad behind the failing diode.
Quote:
Quote:
Is it something related to a bad insulation (electrical?) between the diode and some material next to (in contact with?) it, or is it related to a faulty component?
Exactly. Bad insulator between the diode and the heatsink.

Quote:
So it was not the actual diode that was failing, but the thermal pad.

One begins to appreciate just how difficult manufacturing is and not just design.
Well, the thermal pad caused the diode to fail. It's not like a failed thermal pad alone is going to cause the PSU to cease working. But a failed diode will. :-D

I wonder what Corsair specified on their bill of materials
BOM was correct.

I'll wait till this blows over before I reveal where the mistake was made.
Quote:
Quote:
If the mounting hardware is way over-torqued the thermal pad would be compressed and possibly cut causing failure.

VERY close. ;-)
and here i was ready to blame a bean counter . .

The problem comes from an impurity in the insulator pads used between the PFC diode and the heatsink. When subjected to moisture (e.g. humidity), the impurties crystallize and once harden again when used in normal humidity environments, causes the insulator to crack and tear. Once the insulator cracks, the diode touches the heatsink and it pops.

That's what he said the problem is.

The logo change happened around 2013 or so, so that is irrelevant.

you've ruined TWD/GOT episodes for people, haven't you?


jk, i'm such a stoner for missing/not including all that.

tramp stamp was 2013, which they quickly overhauled 2 years later.

I thought another revision had came more recently though, nvm.
