Apparently all is hunky dory, well I think I'll wait until I wake up and this thread will be at page 650 it will be October 4th and full of glowing praise and no problems...and I'll never at cheese before bed again.

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"

C'mon, you seem intelligent enough to understand that not giving an update to your customers when something is delayed is poor business.  Each day that I don't have my miner after 30 Sep is another day that it is late.  Today is the 11th/12th of October.  I do NOT have a tracking number and I have a day 2 order.  I will be very lucky to get my day 2 order by Oct 15th.  I should have gotten at least 12 updates/explanations/apologies since the 30th but I have not gotten 1.  All I get is canned responses from KNC support saying everything is progressing nicely as the days fly by.  Again, we are talking about an order that was marked as "This order has been scheduled for Shipping on day 2 of production".  What day of production are we on?  Where is my compensation or at the very least an explanation.  It would look like this:

"Hello Mr. ____________,

We apologize but your order will not ship again today.  There have been reports of units catching fire, overheating, locking up, and just generally under-performing so we have decided to stop shipping any further units until we figure this shit out.  As compensation for this delay we will provide you a voucher for 5% off your next order for each day your unit is late.  If we are 20 days late, your next order is absolutely free.

Again, sorry for the delay."

They may be doing amazing engineering but they are doing piss-poor business.

This or something of a similar sentiment would be entirely appropriate.

Edit:  still find it difficult to believe that a brand name commercial PS that powered countless mobos without a hiccup turns out to be out of spec.  Or were the caps bought at a Thai massage parlor?

It is odd. But I have seen it before. (not this exact issue). I've seen things that worked great for multiple things just refuse to work on one particular model. Electronics seem to have problems with daemonic possession

I have also seem quality brands put out one model that just sucked. Anybody remember the first run of USRobotics 28.8kbps modems?

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

I'm tempted to get an Enermax Galaxy and plug a Jupiter into it, then pretend I'm playing Universe Sandbox.

[xstr8guy]

Is the OCZ ZX series okay then?

According to KNC only Corsair makes booby trapped power supplies.


Then again Corsair doesn't actually make power supplies Channel Well and SeaSonic do and between the two of them they make a good portion of the power supplies on the market from just about every brand.

Damn, you beat me to it! This thread moves too fast. But I think my link is for the 2013 list and yours is from 2010.  But I guess it can't hurt to post this information multiple times so people will have a better chance of seeing it.

Let's all donate BTC and send these two on a honeymoon. Anything to get them out of here.

And how much skin do you have in the KNC game MrHempstock? Oh yeah, 25GH. That's kinda sad and pathetic. And actually, just a little gay.

Correct me if I'm wrong, guy.

A guy from GE is going to say that GE VRM's are not working as they should? Or is he going to blame the psu?

The only way to make it fair would be the GE guy + Corsair guy both doing their measurements in the same room.

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.

Congratulations, that Ignore tag will be yellow in no time.
You might want to take a cue from the other guy here who had to delete MULTIPLE posts to keep from looking like a complete anus. Well, less of one, anyway.

Time always tells.

What denial? What head in the sands?? They worked their asses off to improve the issue, and ignored the FUD. The extra fans just waste electricity. The temps quoted from Bertmod were from the VRMs not the ASIC. Please explain what trainwreck exactly? They, in a week have delivered more hashrate than BFL have to date, and more boxes than Avalon ever achieved. They have just released an update that massively improves hashrate. It was a firmware, not a cooling issue. One week. Fair enough if you don't want to deal with them again, their engineering partners on this project think they are incredible, really. That's not hype.

I went from ~410 to ~510 BY COOLING

In my testing, lower temperature doesn't seem to increase the performance of my Jupiter. I've been trying to figure out why my hashrate dropped overnight and decided to remove the case and point a big fan at it which dropped my temps from:

ASIC slot #1: 51.5 ℃
ASIC slot #3: 57.5 ℃
ASIC slot #4: 63.0 ℃
ASIC slot #5: 54.0 ℃

to:

ASIC slot #1: 42.5 ℃
ASIC slot #3: 47.0 ℃
ASIC slot #4: 42.0 ℃
ASIC slot #5: 35.0 ℃

but this did not improve my hashrate at all. Right now I'm not sure what to think about my unit's behavior:



As you can see yesterday it held at around 530GH for around 12 hours before dropping to 450GH over night. After applying .95 it increased back to 500GH but I can not get it back to the 530GH levels I was seeing yesterday even with extra cooling and reverting back to .94. It did this the day before where it was running fine before dropping to 450GH but a simple reboot returned it back to 500+GH. I guess I will just be happy with 500GH and wait for a new firmware but thought I would share the results of my testing.

I haven't read any Billy Goat's Gruff arguments for HF in the last few pages. What gives?
Other than, obviously, that this is a completely inappropriate thread for it (but since that has mattered about 0 I figured I'd ask)

nice.

HashFast will be supplying Seasonic PSU's as stock in the BJ's and Sierra's.
