It's about time they sorted out this burning capacitor issue and if they have already they need to break their mould and communicate with customers about it. IF they think Corsair PSUs are the cause then WTF are they doing not telling us so, then we can avoid damaging our long awaited rigs?
I'm sitting here with a corsair PSU, having never had the KnC recommendation they said they'd give us...with no idea if it was a waste of money or worse ..something that will damage my rig?
Communication is crap. When my rig turns up, do I risk the PSU I have, watch it fry and smile wryly and think to myself "Well they didn't tell us what the problem was, but at least I can have the peace of mind that 'Orama has clean jeans

" . Seriously.
I know it's not your job mate, but who's job is it to communicate these vital issues?
To be fair no one knew a particular PSU may have an underlying problem beforehand, that's not exactly predictable, likewise it is the only common theme currently. It's being looked into, it may not be the definitive answer, but it's an uncanny occurrence, and my advice is precautionary, not based on any science. Just each blown cap has apparently had that PSU. Anotherhost.se is assisting the investigation as DWDoc relayed. When they both have more evidence, they will be able to better inform.
