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.

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

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  

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.

Soros would you post some pics please?

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

Back of the class for both of you. It was already discussed just 2 pages back:

will 750W PSU work?

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:


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
