So the stock EVGA 1300 G2 won't work unless we change the stock cord? I am going to try to use a LEPA 1600w which is 15 amp (180W) per PCI-connector and it has 8 of them. (30 per socket x 4 rails (total of 6 rails on the PS) 12v3-12v6. Is it enough power for the Prisma? I am thinking yes, because 12v x 30amps = 360w. Anyway, I will let you know.... I run two S3s which are 340w on each of the 3 socket on the Lepa G1200, so I think I am good to go here. (I run a total of 6 S3's on each Lepa 1200W)  I believe GrapeApe is using the EVGA 1300 G2 without issue. You just need to split the multi connector pcie cables over multiple blades so that each cable is carrying an equal load. At 1200 watts, that would put around 200 watts on each cable. In this configuration, each blade will have one single connector pcie cable and 1 half of a a dual connector pcie cable. This will only work on PSUs with a shared rail on the pcie output. |

The RPI image should be good to go, I'm just waiting on my usb-uart adapters so I can test it out.
Prismas are on the move again and I hope to have batch 2 and some of batch 3 very soon.

Well partner, you're in luck, cause we've got the best damn Prismas west of the Mississippi! That 1.47 Bitcoin is gonna get you 4 cards totaling' up to a big ole' 1.4th/s of pure bitcoin processing power! That's enough to make your grandpappy's block erupter cry home to momma.
If you're ponderin' spendin' that 1.47 BTC somewhere else, don't forget - Broke is what happens when a cowboy lets his yearnin's get ahead of his earnin's.

I see this thread pop up all the time and everytime I look at I think "damn thats a good deal" (in a US cowboy voice)
I live in the UK and Im trying wrap my head around the price, so its 1.47 bitcoin plus shipping. This includes a full unit with all four cards and total hash rate of 1.4TH.
Thanks

Batch 6 orders to this point have been placed into Batch #5. Batch 6 is extended to Nov 2nd.
Batch 2 should have arrived last week. All batch 2 customers will be compensated and I am making sure of this.

I don't believe any reseller has received more than 20 Prisma units. Be careful guys. If an offer sounds too good to be true, it usually is.

@CrazyGuy
I read that you are offering a version of Minera that is set-up for the Prisma. Where can I find the link to this image? I'm thinking about placing an order and I would like to have everything that I need (PSU, r-pi) ready to go before I do. Thanks
Yes, I am waiting until I have uart adapters in hand so I can test and release the image to my customers. The image will also be compatible with Rockminer devices. |

If I pay today what is estimated time I would receive a Prisma ?
Along the lines of this question. When will you have one on asicpuppy? I hope to have some up on ASICPuppy next week, with the arrival of batch 2. The unfortunate story of batch 2 is that they shipped without a commercial invoice, and were denied entry by customs. They are being reshipped... |

New price on the New Rbox. $79.99
With the RPi that comes with the 8 pack of R-Box is it preloaded with anything? Thinking of giving it as a gift and want to make it as simple as possible. -Dave I actually had to remove that special since Rockminer is no longer providing raspberry pis. 4 still comes with a breakout board. If you still want 8, contact me via PM and we can work something out. |

I got my prisma and controller today. packed well, looks great. My wife was thinking I was crazy getting a package from "crazyguy"
2 newbie questions about the block errupter.
1) where do I plug in to the prisma?
2) I am using a 12v 6 amp connector that fits. Is that safe to use? it says 5v but does not mention how many amps....
As long as you are over 1 amp, you are good, It will only pull what it needs. Hook in to the uart1 port on the controller and check out the second post in this thread for further details on setting the switches etc... |

That's awesome! Thanks for sharing your setup. Waiting on some IEC19 cables so I can get my DPS2000 running.

so Batch #1 should buy the UART if they need it? Not sure if I need one yet since I got the controller. Thanks for the updates guys! Batch #2 should be arriving any day now and all units going forward will come with the USB-UART adapters. I'll be updating the pi image tonight in preperation for their arrival. Also, I have a few A10 Cubie boards, courtesy of Rockminer, so I may work on an image there as well. I'm starting to think that the 4 Prisma limit is really a limitation of the address space and not the raspberry pi, so I'm unsure if the Cubie will actually have any advantages.
Only if you need one early. I'll be sending the adapters out to batch 1 buyers that need them as well. |

I am certainly going to buy a prisma. I am trying to decide which group buy to go with, this one or Canary's. What is the deciding factor for me is when I will receive it.
When, if I order today (10.23.2014), do you estimate I would receive it? Would it still be within October?
Thanks!
ASICMINER has informed me that there will not be an inventory shortage after the 27th. Batch 6 order will be placed on Sunday or once we reach 10 units sold. I will also have units available for immediate purchase on ASICPuppy.net very soon. |

Voltage to your PSU doesn't matter, as long as it can handle it. So either 110v or 220v AC is fine. I believe that PSU has 4 pcie connectors but they are carried over two cables. I suggest using 8 separate cables to your PSU if possible. I highly recommend 2 of sidehack's 750w dell conversion kits to one Prisma for 110-240v operation. |

That makes sense, connectors on a single rail should take path of least resistance.

How did you get 8 Cables on an EVGA 1300? I guess you had some around?
Do those EVGA PSU come with 8 pcie connectors? I would recommend using all 8 connectors to lower the load on each cable. If you are only using 4 of the connectors, make sure the cables and connection points aren't getting hot. You are drawing about 250 watts through each cable with 4, so make sure they are high quality 16 guage and bump up to 8 if possible, or risk melting the cables or connectors.
Okay did some rearranging. Thanks for the advice CrazyGuy I was starting to get concerned about the heat, but now with 8 cables all is well. This does put me in a bind though as far as my psu choice is concerned. Sorry for not explaining. I didn't. I moved the 1300 up to power 3 S3's and am using my EVGA 1500 for the Prisma, it has 8 cables. I'm still in a bind here though because I have 2 1300's coming today and 2 more prismas to power. SHIT... EDIT; I do have a bunch of extra cables is there some configuration I'm missing to get 8 out of it? I didn't think the 2 next to the VGA connectors were in play. yes you can. you should have 6 pcie cables 2 have 2 plugs. 4 have 1 plug. am I correct?? my evga has 6 cables 4 with 1 plug 2 with 2 plugs. look closely this is the 2 two plug cables make believe that fan is the plug end fan on the long tube. this will be two cables with 4 plugs one plug in eacb side. THIS IS NOT ENOUGH you then have the 4 single cables plug one to each side. so six cables pull 1200 watts. each side of the unit has 1 cable with the long plug and 1/2 of the two plug cables I don't have enough hands to hold it in place. but those 6 cables can carry 1200 watts even 1215. if you think you understand the way to wire it please do and shoot a photo to us. I can confirm.  I think this would result in the same 250 watt load on each split cable, even if the cable is going across 2 boards. 1 board with a single cable and half of a split cable would draw 125 watts at each connector. The split cable would provide 125 watts on each board it is connected to. This would result in 250 watts on one cable, regardless of how it is configured. |

what is happening ? i see most people got their orders, why didn't I recived anything ?
anyone else having same issues as me ?
I have no tracking number or anything
When did you order and make payment? There are not very many Prismas in the wild... I have only received my first batch order, and that was made in September. AM is starting to ramp up production, so you shouldn't have to wait much longer |
