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

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
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'

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?

Yeah.  Even when the multi-rails are powerful enough to run mining gear by spec they still have problems.    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.

Quote from: dimitrios;n48044
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.

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.

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:

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

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...

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.

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...

from here -> http://www.memoryexpress.com/Products/MX48291/Reviews

Quote
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?

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?

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 http://i.imgur.com/zC4AhUu.jpg

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?

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...

from here -> http://www.memoryexpress.com/Products/MX48291/Reviews

Quote
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?

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.

It seems that they shutdown on startup.

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.

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

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:
http://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 http://i.imgur.com/zC4AhUu.jpg

There is usable power from that CPU slot on the PSU but unfortunately it is wired differently than the PCIe standard.  Check here to see what I mean: http://www.playtool.com/pages/psuconnectors/connectors.html

You could modify the CPU cable to turn it into a pseudo PCIe though without too much work by removing the pins from the CPU connector and inserting correctly for PCIe.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

This debate is a joke.

Basically, mining is a hedged investment on Bitcoin, and your profit is lower but your risk is also lower than purely investing in Bitcoin.

Furthermore, you help stabilize and secure the network aswell as verify transactions.

Buy and hold is nice, and many miners also do this, but the positive impact on the Bitcoin system is very limited.

You can mine and do all the things you suggest AND recover your costs or you can mine and not recover your costs.

Which would *YOU* rather do Collider ?

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

This is why honest ROI discussions are so important. The future of bitcoin depends on mining being economically sustainable.

Those vendors who avoid ROI discussions, take advantage of people's ignorance or otherwise exploit their customers are doing bitcoin a grave disservice. Its easy to talk the talk, how many of them are walking the walk ?





Mine manufacture's are constantly exploiting newbie miners for more sales. There will be plenty of guys at home getting the stink by their wife and both wondering when they're going to make any money, even $10.

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...

I have ALWAYS spent more money on Seasonic and have always had good luck. I think they make the best power supplies on the market. I've bought and used just about every other brand and all have failed abnormally.
