dc numbers are:

 12.20 volts at the breakout board to psu junction
 12.18 volts at the breakout board pcie jack
 12.11 volts at the s-9 pcie jack

  all really good almost no loss of power from psu to s-9 pcie jack

under 1 %  as  12.20/12.11 -1 = 0.00743   this means .99257 of the volts make it intact to the s-9 pcie jacks

now my ac at the wall comes to 1229.1  as I read 5.1 amps at 241 volts

this psu is rated at 92.6 % so  1229.1 watts  x .926 = 1138.14 watts dc and since i am 11,234 gh at the pool  I am just over .1 watts a gh

as 1138.14/11234 = .1013126 watts per gh.   pretty good !

I suspect  you could run good numbers right up to  13th and freq 600 once I get to the solar array on tues we will try  for some other numbers.

I think this batch 4 is not as efficient as my batch 2 but I will need more tests.

one thing is the board passes well as is it more then 99.2% efficient at a 1230 watt load  this means you lose about 10 watts

I need to use infrared gun and will do so .

 Sound numbers will come later I am doing photos for now.  one good thing about using these breakout boards with the
 dps1600
 dps2000
 dps2500   you get to pick your cooling fans I use the scythe 38mm fan it is on amazon it moves a lot of air and is not a screamer. so the psus make far less noise then the s-9 miner makes

psu breakout board s-9 venting out the door.



closer shot of miner and open door.  if it was the winter I could lay the miner on its side and vent 4 of them out this door.



shot of the open door for venting this is from above the shelf the  miner is under the shelf and behind the moving blanket.

So what does it look like under the blanket?  Also  I know you have a sound meter and can give us some sound numbers please.

@Philipma

Sick.  Thank you.  I will try that.

Do you happen to have some efficiency numbers from your system??

-Optim

I have 1 pdu running a dps-1600 with your board and with a evga 1600 p2.

I get readings of 10 and 11 amps for two s-9s

So 2400 watts to 2600 watts for 24 to 26 th.

I have a second pdu so if I run 1 s-9 the pdu meter will be 5.0 to 5.5 amps as my pdu has  only 2 digits.

I will be able to do this on Friday or Monday

That's not quite as accurate as I was hoping.  Are you able to measure the voltage at the supply output and at the end of the PCI-e cables?  That is the real number I am looking for tbh, though running a power analyzer as described above is the best system level information.

I am only measuring with DC load at the moment and I find it is much less reliable.

-Optim

i can give 5 numbers

ac  amps at the pdu and with only one s-9  it will be 4.8 to 5.3 amps
ac volts at the pdu  it will be about 239 to 241
dc volts at  your board with full draw
dc volts at your board on an unused jack
dc volts at the s-9 end

Awesome.  Those will work.  Would it also be possible to monitor the PSU output voltage under load?  The easiest place to check is on the large connector on the breakout board.

I just talked to my contract manufacturer.  He was able to salvage a single 4k board right now.  I should get it in my hands next week and run some tests.  I don't suppose you want to try this one out in the coming weeks?

-Optim

yes I would like to as i can test it against the other 4k board I have.



I am still waiting on the ups truck but should get the batch 4 s-9 sometime today.

gear is here and it is mining at ck.solo pool
if you look the freq is at 525 the fans are also set low 50%  why did I do this  ..     I am testing in my house  which means my wife will kill me if I set fans to 90%  and try to see if I can go to 625 over clock.
I did run at freq 600 and was close to 12,800gh

 As you see the down clock makes 0 errors
and fans set at 50% are okay not nasty bearable
more to come. on volts etc.


pdu reads 5.1 amps


same pdu


2 car garage is filled with new gear for my kitchen remodel pdu is under the british shoe box
spinning to my left i face the back door and the s-9 is vent out the back door and is hidden by a moving blanket.  the sound is okay in my den next to the garage.

I was one of the first to buy this i bought three and sold one , i use two right  now with the DPS 2000 watt PSU have been for months with out issue if im not mistaken it was designed for the Dps 2000 . i use both boards every day with out fail , planing to buy two more and try them out on the 2500 psu and 1600 psu sense one or two have .

So far I am very happy with these boards.

a kit for 1 s-9 is about 85 usd plus shipping. that is 1 board and 10 pcie wires

Now as a suggestion to the op   I am in NJ you are west coast.  you sent the second set to me in a small flat rate box.

The post office would allow you to order small flat rate boxes for free  and flat rate padded envelope for free.

Stick the gear in the small flat rate box and stick the box in the flat rate padded envelope

these are screen shots of usps order page for small flat rate and padded envelope

http://i.imgur.com/QIk8MCg.png

 http://i.imgur.com/jRYeJP6.png

order 6 packs of 15 envelopes = 90 they will come in a case like this




your cost is about the same and the gear gets a little more protection. And a touch more room if the order is for a board and  12 cables vs 10 cables.  Since the board can fit 12 cables some may want to use all 12 cables.

I am clocking  my s-9 and it is still in China not sure if I get it on fri the first or not.

I know for a fact that the IBM 2kw psu's will comfortably run 3x s5's which is around 1,800w total. From before I updated to s7's http://i.imgur.com/XRlk5Tq.jpg
don't even need fans for them in this config Smiley

well the pair of 2k = 4k on finksy/j4bberwock works okay

the single from optimizer dps 1600   running 1 s-9 works okay

I am sure the single from optimizer dps-2500 will be good.

I have a gold dps-2500  psu   they come in platinum  I am looking for one at a good price.



my gut tells me  the dps-2500 running a  pair of modified s-9ln's will be in my future .  Maybe in my home on oct 1st when my power rates drop from 18 cents to 12 cents for the winter.

I am looking for this dps-2500cb b

     I know you mentioned this is a dps 2500 psu. So does this mean this breakout board can run the dps 1600, dps 2000, and dps 2500 psus?

It should work with all of the PSUs matching the IO config.  I have tested the 2000 PSUs to max load myself and MarkAZ put a write up on the 2000 test in the original thread posted at the beginning of this article.  Phil is covering the rest.

Yes  = dps 1600


I do not know = dps -2000 other people have had great results  I have yet to test my dps-2000 psus


maybe = dps-2500    I have partial results.

I have one of these breakout boards working as I type it is using the dps-1600 psu which can provide up to 1800watts.  It works great.

I have not used it on the dps-2000 psus so I do not know only because I have not tested it. Ohters have and say it works great

I have the second breakout board in the photos above.  it is using the dps-2500 psu which can provide up to 2320 watts. It has not yet been fully tested  it powers on the  the dps-2500  the two attach fans turn on.

I orderedr the fifth s-9  and I have the second board from optimizer.

I tested it with my eBay purchase of the dps 2500 psu   this psu can draw 2320 watts.   but it will run 1 s-9 so should never over tax itself to the board.

I will photo it in a few minutes.

two fans really cool the psu off






ready for the s-9  




switch and space for 3 fans




two fans this size can do two of these psu's

I got the second 2k board today.  the dps-2500 comes on tues.


So far  4 s-9s' and 1 s-7  are in the array


2 s-9's on the 4k board            = flawless   freq 600  2 dps  2000 psu
1 s-9   on optimizer's 2k board = flawless   freq 600   a dps 1600 psu
1 s-9   on EVGA 1600 p2          = flawless  freq  600

1 s-7   on EVGA  1600 t2           = good  freq  600


all have 240 volt ac.  the draw for the 5 pieces is about 25 amps

I think I am going to order another s-9 today

we will have 6 units  which will be  the max for the current setup.

If the boards are built about like mine they'll handle 2500W fine. Before we sold anything we pushed the PSU to about 196A and left it running for a week.
I know the rail layering with 6-pins is quite a bit different than for straight screw terminals so the thickness isn't there, but you also get 2-3 times the area, which reduces current density and improves heat radiation.

I'd have no qualms at all powering three S9 off a 4K setup. I know 2xDPS2K works well for 3xS7.

no worries  my tests will use 1 miner for each psu which will pull about 1200-1500 watts at the wall

I just have the

dps1600 1  with your board

dps2000 2 in a j4bberwock 4k board

dps2500 1 not set up waiting for your second board.

basically any of the above will only run 1 s-9

 I will over clock and  under clock. and take  heat measurements plus give my pdu amp readings,  but I do not think I will ever exceed 1500 watts at the wall on any of the above psu's

The DPS-4K will easily power 2x S9's Phil, and depending on batch it could be closer to 3.  Even the IBM 2880W can power 2x S9's.

208V vs 240V efficiency numbers aren't commonly published, but the difference is likely to be less than 0.5% or so.

For example, an unspecified HP PSU measured in 2007:



BTW I'm making my measurements with a calibrated Xitron 2503AH (http://www.xitrontech.com/products/general-purpose-power-analyzers/#2503ah) with an external 500A precision shunt for the DC current.

Nice.  I am jealous!  We may rely on your for accuracy.

Let me know what numbers you find. 

@Philipma, be careful when testing to 2500.  I have not tested these boards beyond 2kW for an extended period of time.  It should be safe, but try not to exceed 130C anywhere on the board.
