DPS2000BB Breakouts. New updates!

[Optimizer]

A slight update for everyone.

I have acquire a new 6-digit meter for power analysis.  To better gauge the efficiency of the 2kW breakout board, I measure the losses down to 6 significant figures.

Using the same test as the 2880W variant (https://bitcointalk.org/index.php?topic=1698582.0) I came up with the following numbers:

20.850mV drop return side
23.750mV drop +12V side

1900W load (158.3A).

These numbers were measured from the back of the output connector to the furthest PCI-e jack so margin is involved.

That gives a total drop of 44.600mV or by P=I*V, 7.060W.  That is about a 0.4% drop efficiency-wise.  Nice.

This was tested using the load stand below:

Must be nice to have a team.

It's a family.  I have been building and manufacturing with my pops.  We just both happen to be scientists/engnneers!  We are ma and pop, don't worry about that.

Must be nice to have a family close enough to work with. That's pretty cool. Glad y'all are doing stuff well.

I feel the love sidehack!  Hope yours is good as well.

Are these out yet?

Are these out yet?

Yes.  There is stock of all products now.  Connectors came in early.  I have a completed batch of each, 2k, 4k, and 2880 combo.

Did I miss pricing etc.? Your site just links to this topic lol

Ah, I use this thread to post progress on projects.  Pricing is in the Marketplace section of the forums.

Breakouts:
2ks are $50 in singles
4ks are $65 in singles
2880 combo is $70 in singles

Cables:
I have cables and supplies as well. $3.50 per 6pin.  
8pins are backordered for the next 11 weeks but will be available if you're patient.

Supplies:
DPS2000BB is $50 in singles
2880 is $125-150 in singles (depends on market)

I am working out a few other designs for Q1 in this space.  Will update later.  I am also updating the website for pricing and actual product photos.  Much shooping at the moment.

where can i buy them and is 2K PSU and Breakout enough for GPU mining rig with 6 RX 480 s ?  also does this PSU s work on 220V power source. i'm new in GPU mining and sorry for stupid questions

[Optimizer]

All of these supplies are 220VAC in.

You can get a hold of them by contacting sales.

you can do about 9 cards with that psu.

it is a nice quality breakout board as are the cables.

Appreciated Phil!  I did not notice my neglect, I have been much too busy! 

Hope all is well!

Bump for updated stock.  Turn around is 1-2 days on orders below 50!  We have had zero issues on these boards!

We always welcome feedback for board updates!

maybe a 2000 breakout  and 4 six pin and 4 eight pin

let me check  what I need. for sure i will order on monday

[Optimizer]

Oh, nice.  If you can specify the exact connector, that would be no problem.  I never mind adjusting outputs based on need!

Just remember, custom solutions take at least 2 weeks to source the PCB part of the assembly!

Hi Optimizer! How loud do these 2k and 4k power supplies get? Hair dryer or Vacuum cleaner loud? Thanks..

[Optimizer]

reconnect,

Cooling is done separately from the supply.  Air flow must be supplied through the side of the supply with the rest of the miner.

The noise is based on your chassis cooling solution and how much power needs to be vented off

I'm posting to show interest. Your 4K boards are compatible with both the DPS2000BB and the DPS2500BB? So if i understand correctly, since i'm having issue sourcing DPS2000BB, i could get DPS2500BB since they have the same pinout?

Also, do you plan adding voltage control, unless i missed it and you already have a solution for that?

And i would be interested in a sample, i'm totally willing to pay. I'm interested in these PSU's for GPU rigs to run them with PICOs. If you can sell full kits like Finksy i'd be interested as well.
Regardless once i have a full kit for the DPS2000 or 2500, i'd be inclined to post a basic review, if thats any interest to you.
I just need to research and pickup a FLIR, my farm is big enough that i need that to prevent burntout of connectors. Could be useful to rate experience as well. Maybe i can find a legit seller of one on the forum i could pay with Crypto.

Regardless of the little mention bits, i will have 800amps @ 240V to fill by 2018 so i will need quite a bit of server PSUs/BBs if i decide to go with these/Jabb's instead of my current ATX build.

A few people have used the board for the 2500W solution and I have personally run a few tests there.  I have checked the pinout and it looks the same, but ultimately it will be your responsibility to verify everything is OK on your end!  This board is also rated for 2kW, but I am sure it will operate out of specification if you choose to risk that!  Monitor your temperatures during peak loads and verify the board temperature does not exceed 120C at ambient.

Each PCI-e pin individually can source 240W and we have tested under those conditions.

My team originally used the j4bb boards prior to using these cards and they burned out on us.  This is what we use in our rigs and they are open to the community.

We control voltages on the PSU directly.  For the DPS2000BB, we modulate the internal voltage on the supply pot to keep the board assembly process simple!

We also accept BTC if needed.
