2000W Power Breakout Board (DPS2000BB to PC-Ie x12)

[sidehack]

By the way, I just built your cables. Hopefully they do the trick, and should be in the mail tomorrow.

yeah  I am going to use them and try to see what happens to the 2980 I am running.

I am also going to test one of these 2000w boards as someone was kind enough to send me one.

Interesting.  I have a stock of 1k cable coming in from some partners in China.  Was going to test the waters on the website/Amazon.  I am doing 2 footers with 6 pinners on each end.

By the way, who sent you a board!?  Silent knight I suppose.

well I am stuck with the 2880/2980 gear

  so  they have 20 jacks   so if I run 2 avalon 6's   the y cable   allows 16 jacks to go to 8 jacks.  pulling  2200 watts ac.

so 2200/16 =  137.50 watts at each 2880/2980 breakout board jack used.

now  it is 2200/8 = 275 watts at each 2880/2980 breakout board jack used.

  got to be safer  ½ the load on each jack. 


if I did not have all the 2980 psu's  and the boards  switching would be easier. (about 700 usd)

but after testing the 2980's they are true platinum.


and the 2000 watt hps are not plat  most likely they are silver.


I am passing on the donator question.  But it will be nice to test your  gear.

The offer stands if you want to play with the 2880 psu (same pinout as the 2980)

I'm interested, though you should be more concerned with the current at each pin.  With the limitations in layout, I would not exceed 15A per PCI-e connector and even that is pushing it at the board to connector interfacing.

I got your pm.
I am busy today,

 but i am going to the solar array on thurs or friday I will pick up the 2880 and ship it with the  break out board on sat.

[judypug1956]

Phil did you get better results with you y-cable idea?

[philipma1957]

Side hack made up some 39 inch  y cables.

results are perfect at the one day mark on my 2880/2890 boards

quotes below


basically

121.44 watts vs 242.88 watts per breakout board jack

or 10 amps vs 20 amps per breakout board jack

So if you are like me and have a ton of 2880/2980 break out boards the high quality  full length y-cables seem to work

if you have the 2000 watt gear optimizers boards are better the j4bberwocks for the avalon 6

I will be doing testing on them very soon.

I simply say this  j4bberwock's boards do not work great with the avalon 6 due to the higher current needed.
make adjustments for the sake of safety.


@ optimizer I sent a 2880 psu and the 2880  breakout board that was toasted a bit

What do sidehack's cables look like in action?

they are 16 gauge and they plug into 16  jacks on the psu side







on the avalon end 2 avalon 6's have a total of 8 jacks.

so 16 jacks merge into 8 jacks.





this setup draws 8.8 to 9.0 amps of 240 volt power.  it is 40 f this morning

so 8.8 amps of 240 volt power = 2112 watts at the wall/ac

2112/7058 =  0.2992 watts at the pdu/wall

sp the 2980 is a true platinum psu
and these y cables 1 meter long  allow the load on the breakout board jacks to run far cooler

as 2112/16 = 132 watts   vs  2112/8 = 264 watts
i was lazy and used the ac watts I did not convert to dc

so 132 watts x .92 = 121.44   vs 264 x .92 = 242.88

So the 2880 /2980 breakout board  seems to not be able to handle 242.88 dc watts very well
but it seems to do well with 121.44  dc watts

I have a lot of these psu's and boards so getting the custom wires works for me.




note the volts do not sag  this issue is bigger on the avalon 6 then the s-7

I'd be a bit more concerned with the losses incurred at the breakout junction.  These boards are burning up at that end with single cables because the large amount of resistance associated with that design.  You are spreading out the heat with the Y cables but the power is still lost there.  I'd say this is more of a patch for safety.  I'd also cut down on length if you can.  The 16AWG wiring is safe, but the length will equate to voltage losses that may effect the end miner.

@Phil

I just got the 2880 supply.  It looks doable.  I might go for a two board solution but I'm busy with the 4ks.  I'll let you know how it goes.  I'm assuming you want to see this before April and Bitfury?

I can deal with april 15th or so.

 I am working around this for now.

I have a lot of atx psu's in house. And I am looking to do the moving of gear slowly to the solar array.

hi,

hi,
do you have any news about DPS-1200FB common slot breakout boards development ?

if he doesn't yet sidehack is starting sells for his version here https://bitcointalk.org/index.php?topic=1442707.0 


btw if i what read is true the idea and first boards came from side but i would buy both sides and Opt boards over any one else that sells them i have bought from both sellers and there stuff is good.

Hey you two,

I have been dug into a few contracts, but I have not forgotten.  I have some functional 4k prototypes that I can now produce to whoever need.  The DPS1200/800 boards are designed, but I am having issues sourcing connectors (10053363-200LF).  As soon as I am able to readily source those parts or any variants I can push forward on producing these little guys.

I also have completed a design for the 2880 variants, but sourcing these connectors is also proving problematic (the 3 pin connector in right angle variants).  As soon as I hear back from contacts in China I will let you know.  

If anyone knows of a source or substitute I can tack on these boards, you would help streamline the production of these boards.  Any help is appreciated.

I have just received a shipment of 1k PCI-e cables if you are interested.  I saw that other vendors were running low so I stocked up.  

PM me for details or if you have any questions.  And always check the website for updates.  They will be coming very soon.

I am hoping you do find something for the 2880 boards as I have three idle 2980 psus. That would fully allow me to run all my Avalon 6s at platinum level.

Side hack s   Breakout board for the hp 1200 and 800 is pretty good I am doing a head to head test with it and a 1200 watt 250 usd gold psu.

I suppose I could use 1 double board 2000 = 4000 watt psu.

[philipma1957]

dragged this up as i could use a  2000 watt breakout board and some pcie cables.

I have one of your 2000 watt boards and it works well.

I did send you an ibm 2880 osu and a breakout board on my dime.




I wondered if you could pm me a coupon to buy a 2000 watt board and 10 pcie six pin  to six connectors.

I would then place an order for the gear.  thanks phil

thank you just got the email from you.

I will post detailed thread on this board vs the dual board from j4bberwock.

I have 1 of your boards the second one will allow for tests of the dps-1600 and the dps-2500 psus

along with the dps-2000 psu

[E]

I wanted to add some DPS-2000BB efficiency numbers to this thread, as I've recently been measuring DC and AC draw on my S9 at various clock speeds.

Counting 12V cable losses, I'm seeing 88.3 to 88.7% efficiency everywhere from 800W up to 1400W DC. Ignoring cable losses the efficiency is 89.7 to 90%.

This is all at a 208V input voltage... efficiency should be higher with higher input voltage but I haven't been able to test that yet.

so far  I am getting good numbers with his board on the dps-1600 psu.

I am waiting for   the second board and the dps-2500 psu

The goal will be to run them on my pdu that has an amp meter.

right now I am running his one board  with the dps-1600 psu  and running an evga 1600 p2  the two are driving  a pair of s-9's batch 2 set to freq  600 

 the pdu reads 10 amps  and bounces to 11 amps rarely  which would mean 2400 to 2640 watts  for  about 25.0-26.0th
so far so good.

Higher input voltage, implies lower input current (Usually).  If your losses are dominated by I^2 * R, then it will help.

Philipma,

Let me know how it goes.  I don't have the best power analyzer set up.  It would be good to know.
