I want to make a recognition to J4bberwock. I have received the breakout board and the cables and I can say they are of very high qulaity - everything works. The only thing I noticed as an issue was poor contact between IEC-20 socket and the small board for feeding power to the PSU - there have been some sparkles plugging the power cable into the IEC-20 due to the poor contact. I disassembled the IEC-20 from the breakout board, adjusted it and then assembled again all parts back and it's fine now. Overall - very good product quality. Thanks J4bberwock. As for the noise from the PSU - I have never heard anything that loud so far concerning bitcoin mining  Thanks for the feedback. From what you said, it seems that I forgot the soldering of the C20 plug to the small board. It's the last step of the assembly process. And that's why you got sparkles. I can exchange the board if you wish, or if you have access to a soldering iron (almost any would work), you can solder the 3 pins of the C20 socket to the small board. |

And for some reason, it's 20-30% cheaper for me to send to the US than to have the same package sent to me from the US.
Is it because the earth rotate 1180kilometer/hour so you save fuel one way and use more the other way?
Or simply greed from the companies.

For sale SP20 that was used for about a week.
$285 $300 plus shipping (paid in BTC)
One out of four loops does not hash, so it is hashing at 3/4 of regular machine and uses 3/4 of power.
SPT cannot fix it by software adjustments.
I can ship it anywhere as long as you pay for shipping.
Naturally, the easiest is to sell to someone in US because shipping by ground is cheap (~$15).
I run it underclocked at 930-935 GH/553W (at the wall)/fan~25, but it can run at 1150-1200GH if you use more power (I like to run mine underclocked).
If you are technically adept, you might be able to fix the fourth loop (maybe there is a cable disconnect), but I make no guarantees and sell it as 3/4 of Sp20.
bumping with price adjustment How much would it cost to ship to Europe (France)? I guess it won't worth it compared to a new one direct from Spondoolies  |

What is the median price for those PSU and how loud are they ? Thanks  PSUs are usually around 50$ in the US, and noise level is like most of the server PSUs with fans, let's say vacuum cleaner. |

I am very interested in this supply.
I sent a PM about being involved in the next batch.
I am in the US.
There will be a US reseller for the boards, so you'll be able to save on shipping.. |

thank you!!
that's obviously exact the one.
Unfortunately they ship either big quantities only or shipping costs to europe are much higher than 1-2 connectors.
So as a workaround it still would be nice to find the correct names of these "6mm twin copper contacts " to find separate 4 plug female connectors may be at other vendors or shops?
I have some connectors for this PSU in hands. I'll have a look tomorrow to be sure, but I should have at least 4 of them. Part number: 51915-101LF. Datasheet: http://download.siliconexpert.com/pdfs/2010/12/26/3/4/38/223/fci_/manual/51915-101.pdfNo stock anywhere You'll need right angle ones since the PSU covers the power connector. If you want to use at least 5 PSUs, drop me a PM, I can have breakout boards ready in 10 days for this PSU. It was on my "maybe" list. |

Hi:
Do you know where i can find a cheap Bladecenter H PSU , i found delta 2000 on minersource with the price of 29 USD. But i prefer to look for a larger PSU with fan.
Thank you.
For the US market, there were a few of them available on Ebay, around 50$, I haven't checked recently. The guy who will resell the boards for small orders in the US should also be able to sell the PSUs. |

Serious buyers, please send me zip code of shipping address. estimated $60-70 shipping per box. any other difference, they will cover.
Still interested to get them shipped to France. Zip code shouldn't matter, but it's 62111 if you need it. |

Do want these, just ordered some cheap ebay ones. but these, oh so pretty!
be careful with ebay - often times stuff on there is made with 18awg wire, or even thinner than that wire. The reason started making thse custom cables was because an EPS8pin -> PCIe 6pin (with corrected polarity and wiring) caught fire within 2 minutes of experiencing ~150w load. after the fire was out, it was obvious the wiring was thin, likely 20awg, and the 18awg markings on the wire were false. the 16awg and 18awg wiring i use for these cables is high quality, and weighs a lot. Each 24" lead is about 62g in weight due to the thick 16awg core I can confirm what you experienced. I've got two spools of "16AWG" wires with all the correct markings on them, but when I measured them, they were closer to 18 AWG. Despite telling the seller that this is an important safety matter, he kept saying that it was only the external diameter, and it doesn't change the effective quality of the wire. And I was measuring the diameter of the copper, not the PVC insulation, but let's assume it was a language barrier.  The wires on the cables I've got from you last year are even slightly better than 16AWG, very nice stuff for the price. |

First post updated with picture of the actual 22 PCI-E plugs design.
First boards with modded connectors shipped.

Okay 155 gh x .27 = 42 watts once you figure psu in 47 watts .
lets say 5x =
775gh at 235 watts on the low clock.
1365gh at 576 watts on the high clock .
this is a 120 chip design.
right now I can buy the sp20 for under 400 usd.
It will do 970gh at 450 watts
the s-5 will do 1300gh on overclock at 676 watts cost shipped right now is 342 usd if you have a coupon.
For a 120 chip AM to be worth buying it needs to come out soon and be cheap.
At least the board did decently (not .2 watts) more like .3 or .33 watts.
The sp20 can do .46 via underclock.
Price of 120 chip design should be in principle at 230-250 usd w/o the PSU. If the mid-term future Bitcoin price allows significant quantity, the end-game price can be below 200 usd. Does that mean you'll sell the chips for a sub 1200$ for 1000 price? If the answer is yes, I may be interesed to buy a few samples at sample price when they will be available |

thought i would throw a post in here - I sell 24" PCIe---PCIe 16awg cables that are ideal for some of the jabberwocky boards. see my signature link for details
(note: the PCIe-PCIe varient costs a little more and that change isnt shown in my threads pricing system YET - its approx $0.10/cable more expensive than the one-ended varient)
I hope you have some serious stock since I'll have more board soon that will use those cables, and the Bladecenter H board deliveries will start next week. |

I'm still waiting for a quote and dimensions/weight of the boxes.
No answer to my early PM neither.
I may be able to have them shipped to the US instead of shipping direct to me to save you the trouble of international shipping.

There is no image for this but the datasheet (linked from that page and also here seems to fit the connector (see extracted image from datasheet) - MOQ 264 unit @ 4.39186 = 1,159.45 GBP (expected 20/02/2015 as of today) It's the opposite gender, and power pin spacing wasn't good anyway. Here is the correct datasheet. the "5x5.08" power pin spacing is mandatory. http://www.datasheets360.com/pdf/-5473380759948139508The 51940-046LF is 140-150 pieces MOQ, but I already ordered 250 that I should get by the end of january, and a second batch of 250 should reach me before the end of february. if someone can get full engineering drawings for this connector I can make a 3d model for them. Then anyone can print them out and just use J4bber's boards like a DYI kit. That would be great but unfortunately you'd still need the metal connectors, and I doubt we can get them without buying full conectors. And of course, I assume the connectors are patented. You'll have to design some kind of "generic" holder for the metal contacts. It's probably doable, but it's not worth the effort unless you need small quantities of connectors and they don't have samples available. As for DIY kits, if some of you are interested in it and have the skills to do the soldering job, they can request unassembled boards. Beware, because of the 2oz of copper, and 4 layers, heat dissipate quite well, so it isn't the easiest thing to solder by hand. It's better to have the PCB warmed at 100-150°C before soldering. I'll also update this week-end with pictures of the finished 22 PCI-E revision boards since I received the PCBS this afternoon. Uploading pictures won't be possible earlier because I'm currently without phone and internet access, I'm using my mobile as a modem... Hopefully it's supposed to be fixed tomorrow. |

J4bberwock, what are dimensions of that connector for your new board, as I have some Lenovo DPS-800 PSUs and
these are shorter then HP DPS-800 PSUs. I think its like 31 vs 25pins on one side. So maybe this new board for DPS-835
will fit...
Hi, sorry, but your lenovo PSU uses a card edge connector like the DPS1200FBA. I'll dig a little on how to start the PSU (unless you already know how) and which connector should be used. If you have at least 10 PSUs to make, and the connectors is easy to source, it may worth it to make specific boards. Price should range from 30$ to 45$ depending on the price of the connector and options needed on the board Hi J4bberwock, the 12Vsb (stand-by) line will always be live when the system is connected to power. That corresponds to pin B21. To turn on the rest of the PSU, PSON (pin A21) must be shorted to ground (A1-A9, B1-B9). That will turn on the other pins including the +12V rail (A10-A18, B10-B18). Hi, you got a PM, I may have found the mating connector, but I need a few extra infos since I don't have access to this particular PSU. |

Quote me a cheap shipping to France, and I'll probably take the lot.
And size + weight, just in case I could send you a label cheaper than what you quoted.
I assume Escrow is fine.

One last thing that we need to take care of, the cables.
The question is who will need cables, and how many of them.
Since sourcing them usually takes 2 weeks from order to delivery, it's the good time for you to order (from me or someone else, as you wish)
My home made cables are using 1.5mm² copper wires.
according to tables, 16AWG is 1.31mm², 15AWG is 1.65mm²
Price will be
2.5$ for 24"/60cm
3.5$ for 32"/90cm
I can also source cables with 16AWG aluminium wires, the price should be 0.6-0.8$ cheaper than the copper ones.
For those of you who'd want to make the cables or add a connector to existing cables, I'm also able to provide the crimp pins and 6 pins connectors at a fair price:
0.20$ the 6 pins connector, and 0.04$ the crimp pin

Update, I should be able to deliver early for 20-30 boards using modded connectors. I just got the first boards finished using it, and it works exactly as the original one except it's a little more expensive for me, and I need to cut the connector to fit. No price change for you.  If some of you are interested in earlier delivery with those connectors, let me know, and depending on how many I can have done, I'll divide them among you. Shipping is expected by the 19th of january for the boards with modded connectors. |
