Can the 12V power supply in PCIe interface in KC705 be the power of the board?

Jump to solution

In PCIe interface(PCIe_8lane_edge) of KC705, the 12V and 3.3V power pins are unconnected with other device on the board. Can the 12V power supply be the power of the board? Are most of the PCEe cards powered by 12V pins at the interface? How to use 3.3V pins?

Why? because it is unconnected in KC705 or because it can not source enough current for KC705?

Hi @greatmaverick

 

PCIe connector can not power KC705 board. You need to connect 12V adaptor.
