Server PSU for Antminer S1, step by step guide.

[shaxs]

So I am running one of these right now to power 2 ants. Something interesting happen last night. Both miner on it stopped mining for almost 45 minutes. Then it started up again. On it's own. I was just in there checking things out and something happened like it again. Is it possible the power supply is overheating and then running itself way down to cool then turning back up full power again?

Check the graph here: http://eligius.st/~wizkid057/newstats/userstats.php/1HeeAZ7SU3uprNFvZU6NxPf35u358iUZVF. See that dip?

I have to ask.  Was there possibly a power outage?  Are you running two overclocked? EDIT: and was there a pool outage?

No power outage. The other 3 running on traditional power supplies were fine. Each unit that dipped was on two different pools and each seemed to have the same issue.

sometimes server supplies will switch off for a few minutes if overloaded before they switch back on automatically. I had one that would switch off for 5-10 minutes every couple hours at the warm point of the afternoon

Never done with my psus. 12 of them running on 24 oclocked S1s . No problem.

Jason, please measure temp on the contacts of the psus and the plugs you have put.
It should be less than 50C.

Maybe there is heating generated and get transfered inside the psu.

I was in there today installing two new ants on traditional PSUs while I wait for my new stock to come in and the one server PSU running 1 ant turned off completely. So I decided to split the load between multiple server psus. I am now using 2 x PSU to power 3 Ants. I am running 110v electricity in the house and I do not think it is as efficient as 240v. So maybe that is why the PSU is having trouble keeping up. But splitting them between multiple PSUs should be far within the safety margin for these. Now the fans are not as loud either.

What kind of tool would I use to check the temperature?

I use them all on 240V. But I do not believe is that the issue.

I am almost sure that the connector with the holes you use makes bad contact, overheating and transferring the heat inside the psu, making it to disconnect.

You can use a thermometer laser gun , costs less than 10 bucks on ebay.

Otherwise, try to touch it, dont worry it is 12v wont hurt you, and feel if it so hot.

It also could just be a bad PSU. I just got 4 more in the mail. I have 6 total. I still think I am going to run 3 ants off 2 PSUs. My ants with an extra fan pull about 425w each.

I can touch the brass connector and old it no problem. It gets warm but not hot.

Why not just check the logs on the Antminers to see if they rebooted at that time?

[shaxs]

Okay I swapped out the power supply for a different one and it seems to be running much much better. Im writing that other PSU off as bad.

Sure!  But he lost a little production.

For that I have 6 of them. And to put it further, I'll go to work tomorrow and solder at least 1 more as an immediate backup in case 1 of them go bust.

Hi all,
as I am new here I wont try to be the smart guy , I just only like to help the bitcoin community and give ideas for easier operation of your miners as also to save money.
As you know everything is so expensive related to it out there.

I will try to show you bellow how to make a PSU for your Antminer S1.

The cheapest  server PSU that could do the job for the S1s' is the : Delta DPS-835AB, Artesyn 7001138-Y000, IBM x3650 3655 835W (12.1V 69A) , which I bought (and can still buy ) for less than 10$ each on eBay.
http://www.ebay.com/itm/321306693173?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

It is a stable 12V supplier and can handle two S1s' as they both barely reach 62A , overclocked.

Lets say we got it in our hands , here how it looks like:






http://s12.postimg.org/vi8901qhp/image.jpg
















Here are the label details.



http://s13.postimg.org/ft0nhz0sn/image.jpg



















We have to open the outer metal case, which can be done by unbolting 5 small screws.



http://s29.postimg.org/oz24in9lj/image.jpg







http://s27.postimg.org/vx2756dxf/image.jpg






http://s3.postimg.org/rq9d48u8z/image.jpg







http://s9.postimg.org/3lm9c3udr/image.jpg









http://s13.postimg.org/5htcmffev/image.jpg



















Now carefully remove the metal case. Don't pull hard , as it needs no effort to be released.



http://s2.postimg.org/fdpgu9ex5/image.jpg


















Now we have to release the circuit board, as we have to solder underneath of it.
There are 3 screws holding it.


One of them is not very visible, be careful.


http://s30.postimg.org/9r2fgqlwh/image.jpg









http://s16.postimg.org/iigcprfx1/image.jpg



















Here it is , take care not to lose it in the board as it may stick.

http://s1.postimg.org/nym20per3/image.jpg





















Now , lift the board carefully, but don't  break it!  Put a plastic piece, like an insulating tape, so as to make enough space for working with the soldering unit.


http://s10.postimg.org/6e4483sm1/image.jpg























Turn the unit as in the picture and try to solder the two pins as in the picture.

http://s14.postimg.org/xq3gm1pwh/image.jpg






















Be careful not to solder and connect any other pins apart from those two! It is a little tricky, but patience can do the job.



http://s16.postimg.org/bx883qpg5/image.jpg





















I bought some copper bars off a shop supplying electricity materials, like circuit breakers, fuses etc.
Those bars are used for connecting the circuit breakers together, or something like that.
They are sold 1000mm long, 10mm wide and 1,5mm thick. It would be better with 2mm thickness, but could not find at that shop.


http://s28.postimg.org/e5xf5vvul/image.jpg






http://s28.postimg.org/wd7qtfx19/image.jpg





http://s9.postimg.org/sqr1uqxzj/image.jpg























Mark them every 30~35mm and cut them (scissors for metals or a grinder maybe ?)

http://s9.postimg.org/q1rnqz34f/image.jpg





http://s18.postimg.org/73i6ec9c9/image.jpg






http://s21.postimg.org/igyvi47mf/image.jpg



















Now you have to use a stronger soldering unit to solder on the bars.
Do it like in the pictures , but try not to cover the whole surface because a clean part is needed for connecting it to the psu connector.


http://s29.postimg.org/x8nn7wz13/image.jpg




http://s24.postimg.org/3zu5nm4lh/image.jpg





http://s12.postimg.org/kcs6np1el/image.jpg






















Now we need 4 wires for each bar, to supply the current.
Wires in the dimension of 2.5mm² can handle the load as it does not exceed the 16A. The 2.5mm2 can handle up to 20A.
Start by cutting 4 of them 500mm long.


http://s3.postimg.org/nqfzx87xf/image.jpg





















Strip them at least 20mm.


http://s1.postimg.org/jwdv3yv3j/image.jpg





















Now twist all four together and try to hold them steady.


http://s28.postimg.org/nx8zkgfel/image.jpg






















Solder them with plenty of wire to become glossy.

http://s27.postimg.org/vjaigfpj7/image.jpg





http://s3.postimg.org/gd9spr2n7/image.jpg























Now heat the bar again and put the soldered wires over it, it will be very easy to understand that they are well welded.
Dont rush give it a few minutes.



http://s8.postimg.org/mmh1l3tfp/image.jpg




http://s4.postimg.org/k6aqh8jtp/image.jpg

























Now tape only the soldered part.


http://s30.postimg.org/5u76l5obl/image.jpg


























Now, strip also the other sides of the wires.

http://s3.postimg.org/ay12osb37/image.jpg
























If you dont have any PCI -e connectors, you can cut a 24pin ATX type, which can be found at old psus' .

You can create 3 PCIe from a 24 single ATX.

http://s1.postimg.org/jc80srgmn/image.jpg



























Connect the top 3 with negatives, and bottom 3 with the positives.
Be careful, don't fry your S1.

http://s30.postimg.org/abds8fnmp/image.jpg

























Do the same for the 4 other wires, and your are almost done !

http://s3.postimg.org/n6eqzriub/image.jpg






















Push carefully the bars, as shown in the pictures.

Take care about the polarity!!!!

Walla!!

24 overclocked miners working for 2 weeks without issues.

I need your comments!

It's useful

by this way, we can get cheaper and faster rigs

[klondike_bar]

^looks great! I have a few of those in my 14-unit cluster, but primarily use DPS-800GB supplies whenever i can get them to work properly (about 50/50 from the place i buy them at $5/each)

I generally only load 1 Ant per artesyn supply since more causes a horrible fan scream, particularly near full load. 213V circuits reduced the noise slightly i think, and overall improcve most PSU efficiency by 2-5%

[wolf_miner]

Hi, can i connect together upper contact + and lower contact + of DPS-800GB?
I want to do a hole and connect the two side with a copper screw and connect the wire with a fork connector .

Thanks in advance W_M

Yes, to be honest they are a bit loud. But I dont care since they stay in the garage.

can you explain more?

I think there are ready connectors for that psu you mention.

If you want I can check where to order online.

[pmorici]

Amazing. I wonder if it can be done with HP power supply part#403781-001 & 379124-001 - They are 1000watt supplies and very good quality too. I have like 6 of them lying around with no use for them.

It will be much better if you had the connectors for those PSUs.
Do you have them? It is a board with cables that connects with those psus'. Otherwise, you can use pci brackets from old motherboards.

I made some breakout boards for this supply (DPS-800GB A)  If anyone is interested I've got extra parts and can build more.  PM me if you are interested.  Photos below, the ones I've made so far have turned out really nice.  The header on it allows you to also attach it to a Raspberry Pi and monitor and switch it on/off remotely.  The other advantage is you don't have to mod the supply at all so it is still in re-sell-able condition.

Yes , sure can be done. Would like to see if you do it.
