The new Bitmain S3 only has PCIE connectors and no longer supports screw terminals. Bummer. I use cheap and efficient server PSUs that I wired myself for the S1 and they were great. So, not I need to convert those wires into a connector for the S3. I happen to have a friend who works at a computer company and he has been salvaging a bunch of old PSUs. Each one of these has a PSU power connector. I believe I can get 2 to 3 PCIE connectors by cutting them down.

I plan on soldering the wires from the ATX psu connector to a 14 gauge wire running to the PSU. That is how I have it now. 1 14guage (per positive and negative) wire that then is connected to 3 18guage wires for each terminal power block.

Looking at this diagram, is it correct on which is power and which is ground ?



Any one have any suggestions or tips before I start doing this?
