Topic: A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping - page 75. (Read 122577 times)

eh, it's innoscilion  .     we know they make gear, most of us have owned some one time or another;)
its not a new company or anything
do i wish we had vids? pics? ANYTHING to know they physically exist? yupp ;\
But the miners MIGHT not exist yet. tho i think Batch 1 proB does one would hope

idk its not alot of risk for THIS company, they make gear, we all know that

my Biggest irk was them not taking BTC i think any company that supports BTC should accept it as payment
But that's their choice

Wow - you all sure are trusting.

Wiring money to an account with no real contract, product, recourse, etc.  That takes guts.

Got an email this morning saying they had received the wire transfer.
They also sait the upcoming video would better explain PSU configuration.

Does anyone know if I can use 2 PSU's per rig?

According to the description, it requres 8x 6-pin PCIe power plugs. All my existing PSU's only have 6x plugs.
From what I can tell, they are advertizing a max of 1KW per rig, so that's approx 125W (11A) per plug.

I figure if I could run 3x 1000W PSU's (6*3=18 plugs) into 2 rigs (2x8=16 plugs).

Im assuming I would need to tie the ground from all 3 PSU's together, but other than that are there any known issues doing this?

True. An escrow service would be ideal. My guess is that the funds will be used to manufacture the miners. An escrow service wouldn't give Inno access to the funds until it is "released" from the consumer.

So curious - why is there no 3rd party escrow service involved?

I have a trip planned to Shanghai in August -- can I visit their HQ?  See exactly what they are doing?

Doesn't seem so man are you sure? https://bitcoinwisdom.com/litecoin/difficulty

I see ups and downs on the chart the recent spike hasn't reach previous highs in the last 9 months...

They probably do have a bunch going mining anyways

btw, look at LTC Diff, they brought their own farm with the Good chips online, now they can sell the Crap to us

Here is the link I promised on how to make a dual 2560w psu for 300 bucks using a knc titan case (or just zip tie it alone) for 300 bucks or so. About the same price
as one new Corsair 1200i psu. Works slick. Twice the power and same platinum rating.

Just look at the thread below and use the links to follow the pictures. Pretty much plug play and tie down with zip ties no matter how you mount the stuff. Used
electrical crimp blunts for the ends with 15 gauge wire also. My thanks to Maxumark for this idea and the backplate mods. I also have
no other fans on this but what you see. No heat issues at all.

Thread below I started for those looking for a bit of overkill for their A4 Dominators (heck you could probably run 2 of them easy on this setup)

https://bitcointalksearch.org/topic/m.15533861

enjoy!

I checked the website for more information and I don't see what firmware is included.  Anyone know what firmware ships and what version?

I've got a dual unit with backplate sitting in a KNC Jupiter Case.....no fan but the small internal fans.....just put it up today

no issues....the back plate and such is open at both ends (circuit boards) so no heat build up there...perhaps I should get an external fan going...have one not setup yet

anyway seems to work ok....but the price was right platinum level 95% eff 1260 watts each (2 to a back plate) so 2520 watts..total cost with shipping was 300 bucks

I will post pics soon on Swedish asic thread

anyway can run up to 6 cubes easy....and also NO Y ADAPTERS using 15 gauage wire and plug into cubes direct...ie not hot at alll ...bsmt 82F as we speak..this should?
get around the burnt out adapters in some manner....less connections to go poof imho

lastly the main reason to strap it all into a Jupiter case was no rack...could have strapped it to the wire self open....that way....but if I had to strap the thing together with

no real stable case...even a cumbersome .moving around a KNC Jupiter case is preferable....luggable but not a complete rebuild every time I move a psu

anyway when I get time will toss up the pics and link the thread here......but 1 300 buck server psu setup above equiv to 2 corsair 1200i's at 300 a pop at 92% efficiency

half the price seemed like a good deal (further details contact Maxumark) will likely get more and retire the corsair 1200i's for other uses.... I have 3 KNC Jupiter cases

on the cheap left over from salvaging the knc 4/6 port boards to use with qberty knc titan bridges to make knc titan boards...always wondered wth I was gonna do with them

works good for this project and probably would be a good hack for the A4 as well ...bit of overkill but the price is right and I think if 1 psu goes the other can handle 4 cubes

without an issue on the titan and likely a 1000 watt A4 without issue

later

I thought about a server PSU, but those are typically installed in a rackmount enclosure which has lots of extra forced air. I don't know how good the PSU would be just sitting by itself.

I think I saw something about this in some other threads that it is not a good idea to try to use multiple power supplies with a single unit like this.  I think I even saw something similar also posted on the S9 thread as well as those S9's draw a LOT of power and need like all 9 of the pcie connections.  I think you might want to dig around in some of those threads because it may create a problem for you if you try to run a single miner with multiple supplies.

I know a lot of the guys are going with server PSU's to handle the number of pcie connections.  That might be an option here also.  I will have to do some digging.  I am sure some other people with experience here can speak more clearly to this issue than I can.  It seems crazy to me to have to buy a 1600w power supply to drive this miner. 

The miners have 8x pcie 6-pin power ports per rig.
Most power supplies only have 4x or 6x of the 6-pin cables.
Is it possible (electrically) to use 2 separate power supplies on a single miner? Is there any special considerations needed, such as tying the grounds together?

Since they need 1KW per rig, that's about 1250W power supply at 80%, so  I figure I would need either a pair of 680W or 750W PSUs for each miner.
The other option is to get a 1300w or 1600w psu, but most of the 1300w ones also only have 6x pcie power cables. The 1600 seem to have 8x power cables, but most don't ship with all 8 cables and they seem to cost at a premium compared to a pair of 680w or 750w PSUs.

I am getting some questions about the need to ship to Searing.  If you order 3 or more miners you do not need to ship to Searing.  You can tell Chloe exactly where you want your miners shipped. The limitation there is Inno's relationship with DHL from what I gather.

For those of us who only bought 1 or 2 miners and want to take advantage of the group buy to get into the batch 1 miners without buying 3 or more then you should mention your part of the  BCT group buy and that you want to ship to our POC so that we all can partake in the pre-order and drop ship to a single location. 

Searing has been awesome in offering his help here.  It isn't everyday that someone offers to help you out on something like this and there is going to be some leg work on Searing's part to get these miners out to us.  So please consider a tip for him, and providing him feedback here on this site for helping us out.  This is a big deal and we should take care of the members of our community that help like this. 

Thanks again Searing for offering to help us with this group buy.  I really appreciate the help.  I know people don't know me so it is hard to trust people you don't know.  So I am very thankful you offered to step in and help with this.  I owe you one brother! 

Yes, USPS has the postage calculator.  You plugin the zipcode of the origin and destination.  Measure the package and guess a weight.  Plug in the numbers and you get a price, and can even pay and print the postage right there on the web site.  So you can get an exact cost from the web site.  I can walk you through it. 

FML

how the frack do I figure postage..just guess high on the usps calc online .ie fudge a bit over to be safe?......can't really haul them down to the post office and then say stick the postage
on and haul them back to send here is your postage email once it is clear

So far we only have 76 miners coming your way Searing!  LOL

If your ordering 3 or more units you can just place your order and have them shipped where ever you like.  For those of us who are placing orders for smaller numbers of units we have to drop ship them all to one location as a group and then forward the miners.  But since your ordering 3 you can have them shipped right to your host.
