A specific r9 380x. 39 390. and rx 580... When these 3 cards are inserted into the motherboard at all, it simply will not post.... Motherboard works fine with others rx 580s and rx 480s, and these cards work fine in other motherboards...

Does anyone have any idea?

Have you tried with 2 X R9 on that mobo (380x + 390)? What else have you tried? I suspected that was less power

I Have same feeling as this
