Server PSU for Antminer S1, step by step guide.

[smracer]

I have so much work to do....

[tzortz]

This is real power porn.

can you give specs abou those psu's?

Are those old pictures , or you're building now?

[klondike_bar]

Although this is easier and faster than epoxy.

nice job! questions though (after a mediocre and slow job of soldering my own similar work)

-how do you link your (4AWG?) cable to all the (16awg?) smaller lines? Is it a crimped connector or are they somehow soldered?
-how do you tighten your lugs? In the photos it seems like only one would have an accessible screw.
--it looks like you screwed the lug to the PSU connector?

finally - what sort of airflow do these need from the 120mm fans you use?  I connected some low-speed 60mm fans to mine but past 1300w it overheats and switches off

They are all DPS2000BB's.  This pic was taken today.  I am waiting for more lugs to finish the rest.  I have 55 total PSU's.

1) I had the 16awg soldered professionally to the 4 Gauge welding cable.  It was too much work for me to do.

2) I drilled out the outer lug so if I remove the outer screw I can access the inner screw.

3) I am testing using a nut and bolt with copper washers instead of using epoxy since it is messy and time consuming.  Once you TIG weld the two lugs together and wedge them into the PSU they are so tight you can pick it up by the lugs and they don't come loose. 

4) The fans I use are ~.86 amps  @ 12V.

Hi tzortz
Hope all is well for you man.
Listen, can we come up with an idea to put a on/off switch for these PSUs?
Maybe something like toggle switch.
What is your thought on this?

[tzortz]

Hello there Goldar,

sure can be switched on and off with a mini switch.

Let me build one and revise the thread.

Keep following the thread.

Can you show the soldering? Is that possible?

What unit did you use?

It needs massive heat for sure.

[henriquelb]

I need one that does not make much noise, preferably 1000W+. Some suggestion fellows?

Maybe I can even add extra silent coolers on it.

the dps-800 units are good if you run them on 200V+ and at under 800W load.

For the more "Casual" miner here's all the references I used to get my DPS-2000 setup.  I've had 6 Antminer S1 running off a single supply for over a month now.  All of them OC'd with the 393MHz setting.

@Abraxas601 if I use this psu on 110v, it'll work(undervolted)?

Nope, this supply requires a 200-240v input and will not work with 110v.

Should be enough to power 7 S1's

How are you cooling the psus with those side fans?  I cannot clearly see any hole?

No!

That psu is out for 51V and not 12V the S1s needs.

How did you come up with that?

Here's a photo showing the perforated sides on the supply,

Nice.

THere is no internal stock fan?
Or you use the extra ones for safety?

Aw shit
I fcked up.
I must've read over the obvious line stating it is 50V output...damn..
Maybe I can convert it to 12V with a DC/DC Converter?

[Abraxas601]

It has no fans so you need to add them or the supplies thermal protection will kick in and shutdown.
