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?

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

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.

^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

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

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.

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.

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

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!

Just got these in today - I have several dozen for sale and can order more if required.

6-pin PCI-e connector (black)
30cm, 16AWG wires (yellow and black)
tinned ends on wire (1cm tinned)

These are solid connectors and far superior to the garbage 18AWG connectors found on ebay. I have yet to test them on hardware, but there should be absolutely no problem carrying 200W or more (potentially upwards of 250W) through these leads. (In comparison, I have seen other cheap 18awg wiring melt or burn at over 150W)

40 are available right now, SHIPPING FROM TORONTO, CANADA

1-4 units: $3.50 each
5-10 units: $2.75 each
11-20 units: $2.25 each

100a dedicated line being installed now to the "mining shed". Here is a quick pic of the shed itself:

It is air conditioned and will have an inline exhaust fan with registers behind each rack of miners to expel heat produced by the miners.

That looks like a grow house. Be careful that you don't look extremely suspicious by running huge amounts of power to a well-ventilated, light-sealed shed in your yard that you are going in and out of several times a week.

You might get a knock from the cops - followed by the tax-man
