> 600 GH oc capabilities? Is that what I picked up from the hints?

You will need some modifications then. The four pcie connectors can deliver 150w x 4 for a total of max 600w. A standard 4pin molex can deliver 132w per atx specifications. If you rely on the rumored 1.4w/GH, that would give your miner a maximum theoretical of 732w/1.4w = 522.85 GH. If you want more, you´re going to have to solder some extra 8pin pcie connectors in there somewhere.

The PCIE 6 pin or 8 pin connector only has 3 current pins.  They both use Molex Minifit Jr connectors rated at 8 amps per pin.  3*8*12 = 288W ea.

The 75W & 150W limits are part of the PCIe standard which no miner is using, the connectors and wiring can handle much much more.  How much really depends on the PSU itself and what it is capable of delivering TO the connector.

What are the additional 2 wires on the 8 pin then?

They connect directly to the ground.  It allows a PCIe compliant device to perform a ground sense to ensure the proper connector has been attached.  All the power on both a 6 pin and 8 pin connector come from the exact same 3 12V pins.

I was just looking at the specs. I'm sure there is some definite practical use-case for this, but my first thought was "And there I thought there was some actual use for them, not just a way to sell more connector types".

Anyways... thanks for the clarification Smiley
