Hello,

I am building my first mining rig, and searching this forum helped me a lot, so thank you.

My question is, I have 4 R9 280x with powered risers, and 2 EVGA 750w PSUs connected with add2psu.
I know that all the molex connectors from the risers need to go into the main PSU,
However I cannot figure out if I need to plug them into a SATA port or PATA port.

And would it be okay to plug 2 molex with the same cable?

Any advice is appreciated, please let me know if there's more info I need to provide.
