not really , this motherboard works 16/null/16/null OR 8/8/8/8"However, PLX chips have become quite expensive in recent years, so don't expect this board to come cheap."
Nice understatement there!
3.0x16 in to 4x3.0x16 out is 80 lanes, which would require something like a PEX8780 and cost a cool ~$300 on its own or ~$450 for its PEX9781 refresh.
Sorry your information is wrongSupermicro's latest board comes with a PLX chip and four PCIe 3.0 x16 slots.
