Somebody PM'ed me asking for pics of how I soldered a second connector. Well, I don't have any but here is how it looks from the outside. Basically I bought PCI-e splitters from eBay and sacrificed them for the female receptacles. I used 14 AWG black and yellow wires and soldered those to the bottom of board under the location of the original connector.

[aasl]

my order status is still "paid". when I ask for refund, knc told me now it is not possible to ask for refund...

Ok, so I ordered four AX1200i power supplies a while back when they were on offer; until I read this I was thinking I would buy one more and eventually have two cubes on each when (if) second neppy arrives.

Now I have to solder cables to each cube because KnC built these way, way, way over power spec for PCI-e six pin such that even the PSU has the intelligence not to allow that much power through one connector?

My question is, wouldn't it be better to make up some cables that go from two sockets on the PSU to one PCI-e rather than void my year of Neptune warranty? That and demand compensation from KnC for the woeful inadequacy in their design, obviously.

In all this euphoria of those who have - finally - received their miners, I still want to point those who are still waiting for their refunds to another posting in the KnC-forum.

Many of those who asked for a refund received a response saying that they are very busy working on this and that the procedure is more complicated than we all would guess, however, without telling us what this complicated procedure is.

Now, that they are shipping out their hardware, the "excuse" by lie-bot "Kurt" sounds as follows:

We are currently in the production and shipping phase with the Neptune miners and our main priority and focus is on shipping the miners to customers as quickly as possible. Due to this extremely busy period the processing of refunds will be taking longer.

So he basically says that the bookkeeper is shipping or assembling Neptunes? Or that sending out Neptunes is a lot of work for the bookkeeper? That is, IMHO, pure crap.

On the other hand, it is a perfect evidence that KnC is withholding the funds on purpose and not because they are overloaded with work. No bookkeeper in a multi-million-operation would be overloaded by work because 500 parcels are sent out.

So now it isn't a question anymore if it is a B2B-deal or not. It is clear that KnC is fraudulent. So the more people file a legal complaint, the more likely it is that all those who may have damaged Neptunes or Neptunes which will not work properly (including possible hazard) can also file a lawsuit for fraud.

I really really strongly encourage all who are waiting for refunds to send a letter to the police in Sweden. Copy the legal department of the Swedish embassy in your country.

Without knowing the facts - their refund behaviour is 99% due to liquidity issues - there are strong indications for this - they operate hand-to-mouth, they refund what their datacenter is producing.

I got refunded several times in the past by KnC without any issues - all guys still waiting can only hope their datacenter is generating enough profit to clear the backlog soon

It is clear that they are in a liquidity-crisis. However, that's their own fault. A lot of the shareholders have made substantial gains. Now the clients have to suffer.... time for a lawsuit, before they have to file for bankruptcy.

is ok 2 corsair ax 1200 i platinum?

that would be my PSU of choice. without having looked at the exact spec, i'd assume that would suffice to power your new Neptune.

Why need to use 2 1200W?
I think 1 1200(1300) and 1 850W is OK

if use 1x 1200w and 1x850w, how to connect to the 5 box + 1 controler?

1-st option - 2pc 1200W PSUs - one Psu for 3 boxes - another for 2 boxes + controller -> one 1200w PSU - work with 3 boxes
2-nd option - 3pc 850W PSUs - (one PSU for 2 boxes)x2 , another Psu for 1 box + controller -> one 850W PSU - work with 2 boxes

 1300W+850w is OK
I'm with 1 1300w (3 boxes + controler) + 1 850W (2 boxes)

hey a cube draws minimum 400 watts  up to 425w so  u can barelly run 2 cubes on 850 if ur lucky and single rail

u need single rail  evga 1300w g2  u run  3 cubes
and and a 900w -to 1000w second power suplly singel rail  to run 2 cubes plus controller card

fallow as i said or u will burn:) is as simple like that

evga 1300w g2 =3 cubes single rail
900w =2cubes plus card  -single rail

...maybe you'd like to review your calcs and give your excuses then... at actual FW stage (& no OC), ONE (1) cube barely draws 300W of juice... enough room to split them on 860W PSUs too, and enjoy these babies stabilyzing!

I'm not agree
1950W from the wall
this is 1950-10%=1755W from PSUs
1755w/5=351W per box from PSU (I think controler consumation is no high)

 1300W PSU  load is 1053W (+ a little for controler)
850PSU load is 702W

a a i masured  850 watts draw on 2 cubes at the wall without controller card

and previous poster mentions  jsut short of 2000wats for 5 cubes plus controler 2000/5=400w

i guess some cubes use more some less   400 watts is to be safe per cube

I doubt such a thing exists but I think the best solution to avoid warranty issues would be some sort of dual adaptor.

Something like this audio adaptor but with PCI-E plugs obviously

my total draw is close to 2100 so its safe to asume a 400waat avarage per cube and

use single rail  1200w - 1300w = 3 cubes   evga 1300 w g2 im using - single rail
single rail 850 - 900 w = 2cube plus controller cooler master  1000 w im using - singlerail

its always good to be on the safe side:)

Peeps....
I thought every miner knew....

You should only use SINGLE RAIL PSU'S
anything else you are wasting $ and taking huge risks imho

Multi-rail PSU's are SHIT,
I burnt out a couple last Generation before going to all Corsair single-rail
Even when the multi's "worked", they could not keep up with the rest
Even 5 year old-crappy used HP desktop PSU's were better. Just sayin'

Heck my Merc with upgrade module is still running strong on two el cheapo 12v LED 360watt supplies that cost, what, $25 each?  Those and a wall wart for the BBB.

[Winsome]

It is correct that the Corsair has enough power, but you will have issues if you use it with a Neptune. With the Corsair, you'll need to use the workaround described in KnC's troubleshooting guide, and/or be prepared to tinker!

[soy]

Without profit mining is dead. When mining dies, the network dies.

You are wrong. Mining will continue to run even if it will run on red. Just need to find someone to pay for electricity costs.

Got comfortable with the AC keeping my living room cool and my Merc w/upgrade modules and various other smaller devices mining.  Nice and cool 24/7.  Then I got the electric bill for the later half of May and first half of June, that last May the hottest on record for the planet, the bill was 162% of my previous highest electric bill.

Neptune trouble shooting guide out now:
http://forum.kncminer.com/forum/main-category/hardware/48166-neptune-troubleshooting-guide

Ridiculous procedure to make up for knc's lack of testing.

And hilariously, the 6 steps lead you to hash at full speed to incorrect pool  

1. Disconnect all ASIC boards
2. Power on the miner with only the controller board. Once in the GUI, change your pool details to something that is incorrect ( Yes, that is right, since we do not want the ASIC boards to hash at this moment but we still need access to control the ASIC boards)
3.Power down the miner, then re-connect your ASIC boards.
4. Access the GUI and navigate to the advanced tab, once you are here you should change the clock frequency from 450MHz to 50MHz.
5. Finally, gradually increase the clock frequency in increments every few minutes until you reach 450MHz.
6. Your PSU will then work correctly while your miner hashes at full sp

FUD Alert. The 6 steps are only required if you choose certain PSUs eg. Corsair 1200. The steps are not normally necessary with single rail PSUs, eg. good choice is EVGA 1300W G2 Supernova.

Asshole Alert. What is FUD about posting KNC's own troubleshooting guidelines? And pointing out they are incorrect (which they are)?

[Winsome]

Is anyone having problems with Neptune's shutting down due to thermal issues or is this yet more FUD being spread by haters and envious ne'er do wells towards KNC ?

Anyone who? Only 1 Neptune is in the wild!

I figured you'd be lurking somewhere nearby RoadStress … you are never late to a KNC FUD party and your merry band 'o gentlemen can not be far behind. Now that we have OKAVNGR and RS in play, where is the raskul when you need him ?

If we want to start discussing bitcoin miners that you could cook breakfast on, lets start with that howler the SP10.

Thanks for the heads up on some of the trolls to watch out for. As a new member and soon-to-be Neptune owner, I have found this to be a "Wild West" forum for someone like myself. Just here looking for some straight info that might be of benefit to me, and to make a few sincere posts of my own

By Wild West you mean differing opinions? Yes, we have those here. You can choose which to believe. This forum is a good forum and you have a lot of technical people here with various backgrounds that can help you if you have a question. Welcome to the forum from the Ho Ho Troll.

Thanks for the welcome, Ho Ho! I agree that there are a lot of technical people that offer great help here.

Differing opinions are fine, but I'm glad I did my research before reading this thread, because there is also a lot of unmoderated misinformation in this forum (some of it downright malicious). Mining is treacherous enough without individual posters trying to trip you up too!

AX1200i is single rail and the OCP can be adjusted through GUI..

From Corsair website:

Corsair Link™ Integration for monitoring and adjustment of performance, noise, and OCP settings

Dedicated single +12V rail with user-configurable virtual "single rail" and "multi-rail" software modes

[dairy100]

the ax1200I should be able to run the neptune without any special bootup procedures right?
