[PRICE REDUCED] DPS-2000BB 2000W Server PSU Interface Board

[Ninetoe]

stupid question.

if you were connecting let's say 5 antminer s3's to 1 board.

would you use 18 awg or the 32 (or was it 38) awg pci-e cables ?

and why

If by "awg" you mean "inch", I'd probably get the 36". Five miners is a lot to stack around one PSU, and depending on how you're able to organize things, it's not easy to put everything within an 18" radius. If you have your organization planned out you could probably do some 18" and some 36", but the longer cables are only a dollar more and give you a lot more options.

If you're going to go more than 2 antminers stacked in any direction away from the PSU, you will need longer than the 18" cables.

With the 750/board combo, we have the PSU strapped to the top of a stack of 2 S1's.  the 18" cables reach the bottom of the 2nd S1, but with very little slack.  The 36" cables should allow for you to reach them 3 deep.

I have three questions

1) Can i make an order yet?
2) What is the diference between: Current-Sense(CS) and Non-Current-Sense(NCS)?
3) What it's your recommendation for 3 or 4 S3?

Thanks

[sidehack]

We're still in preorder, since the daggum PCB house was well over a week late shipping our boards.

The difference between CS and NCS is NCS exists, but we decided not to make CS.

You should be able to run up to six S3 off a single DPS2K PSU.

sidehack. How are things going along?

[sidehack]

I believe we received a shipping notification about midnight on Monday, which means the boards shipped basically a full week after they were supposed to have been delivered. Once those arrive we still have to populate and test them. We've been pretty busy all week getting the new shop set up, especially the hosting side, but hopefully we'll get that pretty much finished soon. If nothing else goes horribly awry we should be shipping boards next week. Pretty frustrated at the PCB house; we gave them a 3-week-lead order and it turned into a 4.5-week order. They told us two days after it was supposed to ship that it'd probably be shipping one week late and looks like it shipped later than that. Not impressed with their level of communication.

[sidehack]

So, update. Apparently the shipping notification we got was for a different order that we didn't expect to ship until tomorrow. So, thanks a lot guys for getting us the stuff we didn't need early, and there's no evidence yet that the stuff we expected to be delivered a full seven days ago even exists yet.


Edit - they finally gave us a tracking number and the boards were delivered an hour later. So we're checking them over and should start shipping orders tomorrow or Friday.

Thx for the update,

Thats great news

Woohoo my box of DPS-2000BB's came in yesterday cant wait to test these puppies and migrate a bunch of miners. I'm going to use fans salvaged from damaged power supplies that are out of warranty or just not worth it to give some airflow to these puppies.

Thanks for all your work on these, after searching Alibaba for hours looking for cheap high quality +12V DC in masse my searches were fruitless.

Awesome news, thanks for the quick updates.

[bobsag3]

Great to here!

[sidehack]

The first finished boards were shipped out today. We'll have a lot of stuff to do this weekend getting the shop set up and moving prep taken care of, so I don't know how many more will get made to ship by Monday but we'll do our best.

[zulover]

so how much for board and psu bundle?

[sidehack]

Dunno, we're not offering one. Talk to minersource or something, they've got the PSUs.

[zulover]

so where is the best place to order here or the site for the boards and how soon could we expect delivery? shipping to the u.k.

[sidehack]

We've got over a hundred boards pending in the preorder. Earliest we'd be shipping new orders is the end of the week. Everything else you need to know is in the first post.


Pardon if I'm a bit short or "snippy" lately. We had a really good timeline laid out but unfortunately everyone we were relying on for anything ever was between one and three weeks late, so now we're stuck with completing two different board production runs, and gathering for a third, and assembling all the cables, and preparing for a double move, and renovating a shop and building up an 80KW hosting infrastructure from literally zero, with the expected deadline for all of that actually already past. Oh and our entire workforce to complete it all is 2.5 guys, the other 1.5 of whom have wifes and, by extension, lives. So yeah, pretty busy. Not a lot of time to answer questions that have already been answered.

Lol I never knew you could hire 1/2 a man

If by "awg" you mean "inch", I'd probably get the 36".

I don't think he means inch, dude.

[sidehack]

I think he does. Read the context and then consider whether anyone ever would ask for ~36AWG power cables. I know very well what AWG means, but I'm also pretty sure I correctly answered his question.
