Topic: Official Thread: AMT - page 60. (Read 678353 times)

AMT and others, regarding PSU's from China: If they are NOT for computers (multiple voltages out along with high-current +12v), BEWARE. We do NOT want a repeat of BFL's problems with flaming PSU's! If possible verify the mfg dates of them and more importantly what they are (were) for. If they are only high-current +12vdc out they were made for LED lighting, again BEWARE.

About 3 years ago China started a 5-year plan to replace all civic lighting with LED's from building wash floods to the single streetlight in remote villages. They gave mfg for the PSU's & luminaire's (light housings) to whatever local mfgr that was closest and provided no guidance or oversight to what they made. As a result - many many areas had over 50% failures within 1-year of installation. They halted the plan to find the cause: Primarily crappy PSU's built with no regard to temperatures or lifetime. As in cheap filter caps often sitting right next to very warm/hot switching transistors & chokes. Combined with high ambient temps and little to no ventilation, within 2-4k hours, ka-blam.  Problems identified and solved they are now back on track with miniscule # of failures.

However - those crappy +12vdc high-current PSU's are now flooding the markets. You didn't think the mfgr's would just destroy them did ya? Nope. Were sold as-is to unscrupulous resellers.

My suggestion would be to search ebay or Amazon for HP or Dell server power supplies.

so you ordered just on the last day of january/ start of february just after me?? i was guarunteed march delivery i.e 29th ish of march your and my miners are approx 2 days late..... correct me if im wrong. but after checking some details i believe that was my shipping date and i was order 1428.

I'm #1432

Essentially I'd just like to run it as two rigs split the power for the cheaper PSUs.

We know the pi can handle five boards but can it do so from two backplanes either chained or with a usb hub feeding it the info so it just read as one set up?

becuse if that is the case I'd only need the one pi and sd card.

So essentially I'd just need a second cage and backplane and wires.

just for my own note what was your order number?? im curious as to where you relate in the que to me. thanks

Don't have it yet, filed Friday. Besides you don't get to play the you filed a complaint game as you are the ones who are in the wrong and it was with in our full rights to do so. Had you made this sort of offer before you might have found that less complaints would have been filed. 

But more to the point Any and all offers you make to those who have not filed complaints ( and my guess is that is very few here) are valid to all of your customers. Ok so now that we've got numbers 200 for psu + 100 for case + 160 that I already paid for express shipping = $460

So what I would like, and lets forget the extra board.
$28 - Cage- one extra
$28 - Backplane- one extra
$4 - GPIO cable x how many I would need (really not sure of the set up so I'll assume 1 per board  so x5
$12 SDcard one extra
1 extra pi I think it's like 35 if I were to buy it not sure about you though.

That bill comes to $123 and lets me run it as two units which I would prefer as it opens up more room to spread the boards out.

Plus $130 for express shipping. but I already paid 1$60

so $123 for extra parts, that is under the cost of the case and PSU so  $177 extra you get to keep, plus $30 since I overpaid for shipping. So $207 for you.

Holy crap, you are punishing customers who file complaints?? Anyone who has filed a complaint with various agencies, send them a copy of this post. How fucking petty can you be AMT.

what is the nominal power of the 5 boards?? as iv purchased a 520ghs miner and would expect it to be as little as that or due to lack of psu possibly a little more hash i had sent you an email with regards to this from reggy619@........ a couple of days ago now possibly saturday evening. i would be happy to take this option due to being in the uk and needing a 240v psu anyways. so if you could see it to message me back at some point with some specs and maybe / maybe not an offer lol.

order #1428
 mr mellor and mr reg!


EDIT
i am believing from other pics the 5x boards are from the 1.2 ths machine!?! if so send me this shizzle before i change my mind and go get a mc court order from ronnald lmao

We'll figure this out and get back to all of you. For now anyone that would like the kit send a mail to

[email protected]  or  [email protected] 

It would be cheaper to send the kit and then buy the case online and ship it to you from a third party. This is possible.

Although your previous idea was clever. It would allow clients to purchase a more affordable psu, and also give them 6 empty slots to look at it. I'll see if I can formulate that into a paid upgrade package of some sort for the DIY clients.

No you filed a claim. We don't like customers that file claims, especially me because I have to do deal with them.

No. It supersedes the cost of the $200 supply and $100 case. We're looking for a 300 dollar difference here guys. Bulk psu's come in at $200 a piece. Bulk cases at $100.

The value of the additional suggestion you just made would be:

$640 - Asics
$180 - Hashboard
$32 - Heatsink
$28 - Cage
$42 - Main
$28 - Backplane
$4 - GPIO cable
$12 SDcard
$25-40  labor hr's
$130 probable shipping cost on express saver.

$1121  .vs  $300

And didn't you also file a complaint us as well?  We don't like clients that do that, or give them preference in anyway.

What was you're complaint number?

+1 .. I like this even better.

Understood. like I said. I would be perfectly ok with a deferred upgrade coming later while the kit as is comes in. If its a PCB swap and adding the 6th card it seems like a simple enough process for most technically savvy people accepting this.  It seems like a very reasonable compensation and I think most (I imagine) would agree is an acceptable compromise and go a long way for restoring confidence. I imagine this later upgrade would be annotated to the account as well?

The modifications would be the new back plane ( a pcb board itself ) that we would send you. The current back plane allows for only 5 cards period, so even if we wanted to upgrade we couldn't in the moment anyway. So the 6th card would have to be sent with the new back plane.

Alyssa,

And Josh rarely types here. I'll check you're mail and get back to you shortly.

You are correct on that but not that expensive. I checked it out and it is not cheap if its expressed overnight. But not on express saver (which is what i assume would be the case) Least in my case considering I am far closer so not quite as expensive unless you were sending it priority overnight. But in many other cases it would be very pricy. I actually took a look based on my order (2 systems).

However the option of getting that 6th card after all current orders are completed (even if not now) would be an acceptable compromise and I would consider the MPP met even if not with a full upgrade to the next unit. As you already alluded to it being a possibility I would be good with it. If there are modifications that need to be made with a 6th card, that can be simply documented and sent since those of us receiving the kit would be assuming that risk of reconfiguration. #1493 which I thank you for already having responded to.

But yea adding some small compensation (as pretty much every other delayed player has done) would go a long way to easing tensions for most.

PS gotta say its refreshing to see this thread actually taking a turn for productiveness and progress.

What about those who already paid extra for the express shipping?

How about instead of no case and psu we get 6 boards 2 cages and 2 pi's with SD-card which includes the operating system and user interface as well.
Fans - either 8x 80mm or 2 x140mm 2 back planes (since you are getting new ones in soon anyway), and the proper connecting cables. Then we have to get two small PSUs on our own anyway and we can run them as two rigs off of different sockets in the home?

I find that DIY unacceptable as well. I want a refund.
