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.

Yeah, on ROI... Looks like Neptune may or may not make even 5 btc... if it runs perfect.
30% estimated change with a few days to go, and the next few diffchanges look to be similar
Looks like mining just got stomped into commercial and private clouds by all the manufacturers who decided to mine for themselves.
cough cough
With 43 cent electric here, no way mining in Hawaii is profitable anymore
It would be cheaper for me to rent an office or storage unit in Chelan where it's 2.4cents, but difficulty says forget mining imho.

I'm done. As soon as these Neppies ship out, I'll be turning my attention elsewhere. (trading for now)
Good luck to all, and thank you to those who "put up" with me for the last year plus.
If anything, made a few cool friends...   *Aloha.*

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'

Yeah.  Even when the multi-rails are powerful enough to run mining gear by spec,  I seem to have much more problems with multi-rail then single rail PSUs.  I'd go for a 1200 Corsair over a 1500 Enermax any day. And I'd go for a server PSU over both =)



Over on the KNC board there are several complaints that the Corsair AX1200i's are shutting down at startup presumably because of the protection mechanism built into the PSU.
Yeah, I needed to solder a second connector for each Neptune box. After that one AX1200i was able to power 3 boxes at 475 MHz through 6 PCI-e cables.

Soros would you post some pics please?

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)

You can't tell from the outside.  It's the inside.  You have to know the specifications of that particular psu. Most higher end and high end psu will be single 12v rail.

So can i get some examples of 750 and 850 watt PSU's that are single rail?

Thanks,

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  Cheesy

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

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:

Quote
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

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.

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.

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! Smiley
