An autopart that Finsky recommended that can run a motherboard.

Yes - I'm splitting each wire coming out with a PCI 6 pin to 2 6 pin splitter.  

So all your video cards are 6 pin?  None of them have 8 pin?

I can't speak in regards to his video cards, but the only difference between 8 and 6 pin cables is that 8-pin have 2 extra ground circuits.  They can't effectively carry any more load given the same gauge wiring than 6-pin cables.  The reason they created 8 pin vs 6 pin was for standardization, 6-pin PCIe cables were only originally rated for 75W, the 8-pin cables have wiring rated for 150W.  The 16awg 6-pin cables I personally carry are rated for well over 250W.

So, you can get away with just grounding the 2 extra pins when powering GPU's with sufficient awg 6-pin cables like mine.

Good to know.  Thanks for the info Finsky.

Too bad these are 220W. 

You can use the dryer outlet or the stove outlet if you are not using those currently.

110V-120V is just not enough to run large PSU's, the required amperage would be crazy.

how much  power does the antminer s7 board give out for fans can it handle the delta fans

voltage : 12V
 
Current  : 3.9A
 
Power : 46.8W

i want to try the delta TFC1212DE

is it a bad idea?

The S7 will have no problem powering that fan from the controller board, that is a similar fan to what they come shipped with.

24" PCIe cables back in stock, packages are all up for sale.

So I had to post up here and brag on Finksy.  Even after offering bounties (which I still have to pay and will) by FAR he was the most helpful in getting me up and running using just the server PSU's for GPU mining.  

They are loud but I have FAR less trouble out of them than consumer PSU's.  Also if you want to make them quieter it's pretty easy to build a box with mattress padding to cover the front (leaving the back open and not suffocating the fans).  

After making my own wiring harnesses it runs like a charm, they stay cool and the 12v wires are extremely substantial (I'm delivering 200w per wire and running 2400 to 2600w per PSU).

You won't regret dealing with this guy.

what wire did you use to extend your GPU power cables? i guess it is modded using stranded wire?

I currently do not carry 6+2 pin PCIe cables, however I am currently exploring some cheap & easy solutions to add the extra 2 ground pins.

Finksy Hi how are you... Joan and Ivan from venezuelan told me about you, that you sell many diferent models of breakboards... i am looking for the HP 1300 Breakboard... that it have 8 pci-e Ports... with they cables... May I ask if you have Stock ? could you please contact to me by Private Massage  to talk... thanks so much...!

I found these on ebay, i ordered a few just to try them out.

Bump, packages in stock and ready to ship!

[bronxnua]

I've got 3 new 220v 30a lines being installed today.  Might have to look at trying one or three out when you solve the fan noise issue.

Currently working on it.

good idea - the only reason the fans were on the end was to address space requirements.


and you can get your dremel took out and cut the end off also.

nice where did you get the fan.. did you make it with that connector?  is that enough to cool it down?

[dance191]

I gotta say Finksy really comes through.  I put in a few orders and he made everything happen ASAP.  All of the boards are top notch and everything is perfect.  Thanks Finksy!!!

[crowetic]

Do you make custom breakout boards, and/or setup my backplanes if I were to ship them to you? I've got a bunch of DPS 1200FB psu's and the backplanes that hold 4 of them, but I'm not certain on the wiring... Would be nice if someone professional such as yourself would be able to wire them up for me?

[Finksy]

Bump! Many packages ready to ship now, have power ready for your S9!

@dance191 thank you for the kind words.  I do my best

@ crowetic  Sorry I do not make any custom boards, all my boards were developed by J4bberwock I simply build them and sell them for North America.   It won't be worth your time to ship PSU's to me to custom wire and ship back to you, you'd be better off finding someone local, do it yourself or source something different unfortunately.  If you're keen to try doing it yourself, the RC forums are a gold mine for how-to's and pinouts for server PSU's, I'm sure you'd find one for the DPS 1200FB.  I will warn you though, I'm not sure excatly why, but I had a large batch of DPS 1200 FBA psu's that I had bought and wired up myself to sell with some S5's, and for whatever reason I could not get them to put out less than 13.x volts.  I believe it was responsible for frying a customer's S5 due to over-volting.

hey guys, looking at getting these for my gpu miners.

Is there any chance of a breakout board that Has ATX and cpu connections on it? would rather use one psu rather then one for mobo and one for the gpus. preferable pay in BTC and live in Aus.

Cheers

J4bberwock currently has one in development, however at this time I'm not aware of any server PSU breakout boards that have provision for 24-pin connector with +5 and +3.3V or CPU power for MoBo.  You can power cards with server PSU and power risers/motherboard with lower-power ATX PSU though.

[Finksy]

Bump, get your PSU setups in time for S9's!

[Finksy]

Bump, S9's are power hungry.  IBM 2880W has what you need!
