Those EVGA 1300s work great for my FrankenJup. But others had problems trying to run more than 5 FrankenJup modules. So I would proceed with caution. Check the KNC forum for more discussions about PSUs.

thanks, I'm waiting a response from the guy that did the video, I'll relay his answer if he does.

I guess the big question I have for those who have received their Neptune's in the US and in Canada (if there aren't Canadian's other than myself in this thread) did you have to pay duty if so how how much?

Thanks,



 You don't have to pay duty but you have to pay the HST @ 13% of the declared value after converting to CAD which is a real downer since our dollar plummeted against the USD since last NOV.  I've had to pay this one every miner I've purchased... yes I got BFL'd.
 

depends what province.

Alberta should pay 5% GST only.

*edit* plus probably some kind of brokerage fee

Yikes, so I guess I would like to know if any of the B1 customers are from Canada here and when they get their Neptune what does KNC mark its value as, because that's how they determine the HST. For us Canadians that could mean paying an extra $1500.


I cancelled my order so I wont know about the Neptune but when I got my Saturn they marked the full price on it.  I was expecting the same for the Neptune.  I would think anyone who has received their Neptune order could tell you what price was declared on the shipping label.
Does anyone have that info?


They will undoubtedly list the full price for the unit.

I don't know if provincial tax applies, because AB doesn't have provincial tax, (honestly I don't even know what HST is?)

but you will at minimum have to pay the 5% GST.

corsair ax1200 is quite a good psu, but it cannot work for neppy?

for those who received their neptunes, what PSU can make neppy work?

It seems that they shutdown on startup.

I'm embarrased to say I didn't think it would be a problem, all my previous supplies have been single rail, so I've never had the experience so I bought a couple Antec 1300W  4 X 25 AMP PSU's cuz I thought they'd be fine and they were on a massive sale???

I haven't opened them yet, should I try to exchange?

Yes.

point taken, - is http://www.memoryexpress.com/Products/MX48291 sufficient?

this PSU I think is the same as in the video, but it seems that the included cables might not be up to snuff...

The stock cables that come with the power supply seem fairly cheaply braided, however they do sell single braided cable sets for 90 buck that make a huge difference


I guess what I'm asking is what is the most trusted PSU to run this beast?

Is it ok to use "Peripheral - IDE/SATA" PSU slots to connect to a Jupiter (6-pin PCI):

In particular, can I connect four of these 6-pin cables into a Jupiter:
http://www.moddiy.com/products/6%252dPin-PSU-Modular-Power-Cable-to-PCI%252dE-%2830cm%29.html

connected with the four 6-pin Peripheral - IDE/SATA PSU slots on this power supply on the left:
https://i.imgur.com/zC4AhUu.jpg

Or are the Peripherals/IDE/SATA NOT to be used?

The power supply on the left has 4 12-pin connectors, but one of them is fried (bottom right corner). So, I'm wondering if instead it's possible to use the 6-in PSU slots that say "Peripheral - IDE/SATA" on it and connect them to the four 6-pin cables of the Jupiter? Thank you

The answer is yes and no.  If you were inclined to create a franken-cable that took the 12V lines from 3 of the peripheral connectors then you could theoretically source some more power from there into a PCIe connector.

As for the idea you presented in using that cable to just plug in directly to the peripheral section, that will not work.  The pins in the peripheral section contain 2 grounds, a 5V line, a 3.3V line and the 12V line.  It is not designed as a PCIe compatible connection and will not work as is.

Thanks for your help. Since my 4th PCI-e slot is fried, can I still use the CPU slot on the PSU instead to connect to one of the 6+2 pins on the Jupiter, as long as I still use a proper PCI-E cable? (I would use the other 3 working PCI-E slot with the rest of the 6+2's). See image https://i.imgur.com/zC4AhUu.jpg

I have the same psu as you...fried a cable too as well...i think its cause they used cheap cables and using 2 off one plug wasn't good...wish i used all 4 plugs and i probably wouldn't have fried that plug Sad

dunno if you could...but you could always just open up the psu and solder wires directly to use that pcie plug...

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.

Please share your work with the class.  Smiley

I have the same issue using a Corsair 1200i power supply. After a couple of minutes the power supply shuts down. What did KNC tell you to do? This is one of the best power supplies out there this is very odd.

@theshmadz

I am not familiar with multiple PSU's. How to set up single rail or multi rails? what is the best option to make neptune work? suppose I have three 850W PSU.

Each PSU is single  OR  multi rail.
Each rail needs to be capable 300 Watt minimum for each ASIC plugged into that rail.
(based on KnC statements)
For multi rail supplies you gotta dig into the literature for specifics on each rail.

For your 3 x 850 question, I'll assume single rail PSUs.
Use 2 ASIC per PSU and power controller cube from 3rd PSU with one ASIC.
If the 'suits' are to be believed this will load the 850's  to around 600 Watts.

If your three 850W PSUs are single rail and were in one box it would be a 'triple rail 2550W with 850W rails'.

Hope this helps.
Please if possible understand what is going on before applying power.
Internet advice can be faulty even with good intentions!!!

YMMV
Smiley


very helpful, thank you. One additional question if you please.

Is it a bad thing to load say, 3 out of 4 rails to near full and leave the 4th one doing nothing?


also

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.

This the first time I have heard about Single and Multi-Rail PSU's. LOL

So can you or someone provide something that demonstrates the physical difference between these types?

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.*

Aloha too
