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...

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?

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

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...

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.

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.

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.

It's funny you mention this because the slot that got fried was on a Seasonic PSU   Cheesy (But yeah I get it it was probably a cheap wire).  I've had more luck with Corsairs, but then again I'm not too experienced.

Cablez - if what you're saying is correct - namely that you can't use the CPU slot with a PCI-E cable - then I don't understand why my 850W Seasonic PSU has slots indistinguishable between CPU/PCI-E. In other words, it seems like you can plug in anything CPU or PCI-E in here, or no:??


EDIT: Or maybe if it just says CPU only, then it means exactly that. But if it says CPU/PCI-E then it's like a "hybrid."? That would be my guess.

Corsair don't actually manufacture their own PSUs. They are made by Seasonic and Flextronics...

i am a bit confused here. in what circumstance the neptune will fry a PSU slot? because the elec current is too huge?

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.

This is correct the power and grounds are on opposites of each other.

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.

It's funny you mention this because the slot that got fried was on a Seasonic PSU   Cheesy (But yeah I get it it was probably a cheap wire).  I've had more luck with Corsairs, but then again I'm not too experienced.

Cablez - if what you're saying is correct - namely that you can't use the CPU slot with a PCI-E cable - then I don't understand why my 850W Seasonic PSU has slots indistinguishable between CPU/PCI-E. In other words, it seems like you can plug in anything CPU or PCI-E in here, or no:??


EDIT: Or maybe if it just says CPU only, then it means exactly that. But if it says CPU/PCI-E then it's like a "hybrid."? That would be my guess.

The pcie and cpu power slots on the psu are interchangeable. But they give you a specific cable to use for the cpu connection because they reverse the pins layout on this connector for the cpu.  Versus the pin to pin layout for a regular pcie but that means 3 power and 6 grounds versus 4 power and 4 grounds that a regular 8 pin cpu which is basically 2 x 4 pin cpu power sets gives.

Over clockers would prefer a dedicated 8 pin cpu power plug than a hybrid 8pin/pcie slot.

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

Unless you're solo mining or mining using p2pool you're note validating txs. In fact pointing your hw to your preferred pool doesn't even make you a miner, technically you're a hashser.

Quick update and rough numbers (very rough)

My control board shipped with neptune-rc6 FW
Still a bfgminer checkbox on the 'Mining' web page but it has no effect.
Guess I gotta try and hand roll bfgminer.
They removed the SPI clock and voltage options from the 'Advanced' page
The clock is likely 7-8x faster than default hoopiter cause of 1440 core per ASIC instead of 192
Still 4 die per ASIC, each die now has 360 cores instead of 48

There is an LCD on control board with IP address and hashrate
There is a BRIGHT backlite on the LCD.
(I keep thinking I left my LED flashlight on)
The power on white(really RGB LED) light is brighter still.
If ya lookin at the LCD waiting for it to boot when the white light comes on YIKES!


I tested each box seperately
All ASIC, all die, all VRM checked out.
No idea on individual core health yet.
There was a parade of cores disabling, no idea if it is more or less than 28nm yet
I didn't time the tests ~20-40 minutes per ASIC
I just waited till the numbers looked settled

380-400 Watts @ the wall per ASIC

280-290 Watts per ASIC as reported on 'Advanced' webpage
Roughly 0.6 Watt per GH/s @ the ASIC

I have  a plat PSU runnin @ the sweet spot near 50% of rated current,
should be >10% loss in the PSU the rest of difference is prolly VRMs effiency
(plus a few watts to keep the cable warm)

660-670 GH/s per ASIC with default 475MHz clock
~3.3T stock clock.
(I just added them up, not run 5 at once yet)

HW errors between 0.1% and 0.9% average under 0.5%
I predict improvement with better cooling and volt adjust
(If I had bfgminer I'd have a better idea with individual core statistics)

50-55 degree C ASIC temp with ambient @ 27 C

VRM temps between 70-90 C prolly 76 average

The PCIe cable gets a bit warm, I only tried one ASIC @ 500 MHz for a few minutes, it worked

The cardboard box is much improved, triple walled tough stuff
Inside the box is another triple walled origami nest below and above that is doubled toward the outside of box
3 layers of triple walled cardboard
Slight issue with the nest though, it is exact size of cube but fan grill is external and can (did) get bent in, causing it to sound like a bicycle with playing cards in the spokes for motor noise

I retract earlier statement about case strength
(open mouth, change feet)
The strength relies on fasteners and the cube screw holes strip if ya look at them
(might be a good asset for a stripper but not for a miner case)
IMneverHO
 
She ain't perfect but the ASIC seems solid enough!

YMMV

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.

Mine has been running for 2 days now on the EVGA's, I chose them as I have used them to power 3 ants at a time (1200w) with no problems.

Running the neptune, the cables are a little warmer than I'm comfortable with but they aren't red hot.

Use a voltmeter on DC volts & check 8pin EPS (CPU) polarity,to see if its the cable that reverses or in the PSU (cause most cables are all black wires)...get another PSU & check the PCIE polarity to be sure your correct...simple  Wink
