So I had bought a couple original design ASICMiner Blades that didn't come with the green power connector.  Fortunately I was able to solder up my own connections but they are a bit fragile.  Would like to return to the more robust screw connector.  Just need the part that plugs into the existing green PCB power connector with the screw down terminals.

Found this:
http://www.ebay.com/itm/10-pcs-5-08mm-Angle-4-pin-Screw-Terminal-Block-Connector-Pluggable-Type-Green-/400365142419

Wondered if that would work, though the "sides" of the connector on the blades are closed not open like the one on eBay so it makes me hesitant.

Thoughts/Ideas anyone?

They look exactly like the connectors that come with the blades.  But don't quote me on it.  Wink

Those are "2EDG" connectors.

I bought a bunch of the 3-pin type for my Ztex boards from Kesun Electronics on aliexpress.

The ones in the ebay listing above would probably also work.  They look the same, and specify the same 5.08mm pin spacing.

Worse comes to worse, you can safely trim the receptacle plug with a pair of wire cutters if you have any clearance issues. But they should work fine as-is.

Necro bumping this to say thanks. I burned a couple terminals because I screwed up on how you insert the wire into the terminal (dont ask me how). Also led me to finding replacement terminal blocks for the backplane. I hope I get them soon, so I can sell them as a ready-to-go kit.

If you don't pay attention its possible to put the wire between the metal and plastic rather than metal metal, causing the plastic to obviously burn. Its a bit of a flaw in design [room for user error], but hey, they cost nothing to make.

Just thought I'd mention it for anyone looking in the future, you can MAKE the 4-pin power connectors work off of standard PC power supplies.  Note that you'll still need to change the wiring to get 12V and Ground to the correct pins, but this does work.
