It's an ongoing investigation, but if you want to play it safe, for sure the Corsair V850 has not shown any problems this end, and is used throughout the hosting currently.
you mean Cooler Master v850 and not corsair v850. I bought two CORSAIR AX860 860W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139044any of you work with that one?

Probably better to turn it off with the paper clip than the main switch. Should be more graceful.

don''t turn it off and on a lot then.. That is what was causing the issue from what he said
which one tell that?
maybe that make chips faulty?
or make the psu wrong???
that particular PSU was sending more current so that cap couldn't handle getting hit again without discharging its high load It would be a voltage spike blowing the capacitor. I had a great old switching supply putting out 16.5VDC from an old heavy laptop. I had a zTex FPGA board mounted in a small box with fans. The small box had a voltage regulator on perf board to knock down the voltage from 16.5 to 12v. I added an off/on switch to the box. Big mistake. Flipped it off for some reason. Now with the off/on switch in place I wasn't unplugging the supply. The switching supply, floating, was looking at an open with the switch on off. A voltage built up and I was eventually startled with a BANG, very loud. A cap had blown. Could it be the switching supplies are being unplugged while still powered up, allowing a voltage buildup. Even if unplugged the reattached to power, that buildup of excessive voltage on the disconnected PCIE-4 leads might still be there. Plug it in a BAM.

Is KNC updating firmware as they go out the door?

Does it affect any Network Protection Statement? No. Any customers that purchased for October are being delivered in October. Any customers after, will get theirs in November, after a month’s gap. No special treatment. Thanks for the update. Not trying to come across as racist. It's just that China reminds me of the Nation 0-1 in the Animatrix. If there is still a planned limit, then cool. It is hard to believe that a company would not keep producing for their own bottom line though. I'll just have to trust you on that one. And what happens if they do keep producing and effects yours? You don't buy again...

orama,
thx for update!
i got one corsair 1050 hx running.
is that also a problem or just the 850???
Mate, cannot say. Not what i've been focusing on to be fair. Gut feeling it's part of the same brand/model family, so I would rather take a swerve. It's supplying to much current from what I understand. Something about a safety in the PSU being triggered and the cap smokes after the PSU is switched back on. They don't have every brand of ATX here to test. Anotherhost popped by with theirs is what I heard, it just so happened that on all those reported it was the same PSU at fault. It's an ongoing investigation, but if you want to play it safe, for sure the Corsair V850 has not shown any problems this end, and is used throughout the hosting currently. This whole 'blame the power supply' story sounds pretty suspect to me. The power supply can't 'force' current into a board... There is clearly a board design problem here, and it looks to me to be highly unlikely that any specific known-to-be-fully-standards-compliant power supply would be more likely to cause it, other than simply being capable of providing higher instantaneous current - which is clearly not a flaw in a power supply. I imagine this will turn out to be something that happens when you do something like turning the power on and off at exactly the wrong cadence, or something like that. Somebody probably left a necessary diode out of the design.

Correct, and capacitors can't be damaged by having current applied "before they've discharged their load", nor could a PSU force current through one. Capacitors would be damaged by excessive voltage over their rated dielectric rating, and PSUs are designed to keep voltage constant through their rated current capacity. There's a great deal of bad/incorrect information being passed around here.

Have i just killed the Jupiter!?! Just setup a new miner. Fired it up and recognized that one front-fan didnt work. I didnt care cause without the case airflow should be OK. I started to change the setting via the webinterface and then the miner suddenly shut down. I checked everything and found that the front-fan wasnt working cause a blade was STUCK! So i "unstuck" it and fired the miner up again but NOTHING happens........... Whats going on??? UPDATE: Fan is working normal again. Situation is like this: I start the miner and everything is OK, i can access the webinterface and edit things. After pretty exactly 1 min the miner shuts down abruptly... this is PSU fault, i think!

So then you are against what KnC is trying to do? (Selling ASIC's in general?)
Of course not. But Im not going to buy them either. The only way I would consider investing in asics is through something like asicminer (shares), since their incentive is not opposed to their customers/investors.

2nd request. No, didn't think they had stopped, as per what I previously wrote; I'm no where near the manu facility anymore, i'm in Stockholm flipping a coin as to whether I sort out this accommodation mess, or head back to the UK and sort myself out there.

Dude it's b/c of the Swedish coed's there are no rooms, everyone coming back to uni this past month and undersupply of student residence means Stockholm has even more of an accommodation issue than it's notoriously known for. Trust me i'm eager to share a place with a cute Swedish girl with a diligent study habit for the sake of the community!
