Server PSU for Antminer S1, step by step guide.

[CartmanSPC]

My advice for a simple non-reversible modification:
1) PS-ON : achieve this by using a tiny flattip to pop up pins 3&4 and bend them into contact with eachother. add a quick hit of solder to make this permanent

Are these pins 3 & 4 that your bending together? Just the bottom row pins right?

I wanted to see it , too , done.


Please pictures!

I cant get a good picture sinc emy units are in thier current housing location and not my home - but yes it is those two pins.   they are shaped a bit like :     ----'''\_    with the tip wedged into/under the plastic around it.

just grab a tiny flathead (a jewellers/eyeglasses sized flathead is best) and pry up the pins. it wont take much pressure and they will unseat and spring up very slightly when popped free. bend them together and add a quick solder joint. 

If you are able to solder them together without prying them up thats even easier, but they are just far enought apart that its tough to do so with most soldering tips. prying them up and towards eachother is quick and easy

I was thinking about ordering an Antminer S1 from Bitmain once they have them in stock again and was wondering if they are shipping now with the PCI-E power connector on them or will I have to strip wires and screw them down into the wire connector?

All are pci-e now.

Wondering...should I go with 16 AWG or is 18 AWG adequate?

18 awg would do, as are 3 wires x 7 amps (amp limit) = 21 amps.
Each blade will not absorb more than 15-17 amps overclocked.

But, still are close to the limit and the 18 awg will get a little warm.

I would go for 16awg to be safe for any unpredictable reason.

Thanks. The 16awg was only a $1 more

I sell 16AWG pci-e cables in my sig.   I advise caution when using 18awg wires as I have found that some places do not seem to actually use proper 18 gauge wire.

If you cut open a 18awg wire from ebay, its usually only a few threads of wire, perhaps a 22awg in reality. Cheap wires can and do cause fires

So, what is the verdict on these nice brass terminal lugs?
Would they make good contact with having a hole in the center?
Are they OK to use?
Thanks

1) copper
2) even with a hole they are at least 20x larger on contact than the pins they connect to inside the PSU.

These are rated for a lot more amps than that PSU puts out.

But you can always fill in the whole hole

By the way I meant "copper" not brass.
miaviator, I know, this was your finding .
Are you using them on any of your PSUs without filling the whole?
Any problem with them so far?

wish that this was posted in Jan or Feb

You are right, fire can be caused by cheap ebay wires, I have seen such case where they melted , touched each other and for luck the psu protection switched off.
Very dangerous when playing with the wrong cross section.

Really, miaviator , have they been working well so far? Have you measured any temps close to the contact?

[klondike_bar]

^miaviator shouldnt have issues with those connectors. thats a massive chunk of copper, probably much more material than a 4AWG wire and capable of close to 200A I would imagine

No issues.  Hot glue helps to prevent slippage.  Temps are fine via ir probe.

I use 14 awg stranded leads to each pcie adapter at two per PSU for ants

18 awg stranded DC pigtails x 12 for griseeds using 4 way splitters I power 48 seeds.

Great miaviator.
Built 16AWG (PCI-E) and 12AWG at the end.
Now, Just waiting for the PSUs arrive.
