After trying this, and still getting nothing, I went to bed as it was late. Went to try again this morning, and only the Ram leds turned on, the the board rgb, the fans, the harddrive, and the GPU all never came to life. Switched to a known good power supply, tried it there. Nothing. I am now fairly confident the board was DOA. I even took it apart, put it back together and check each and every piece for any dirt or grime or corrosion to see if maybe a lead was bad.and everything came looked clean and in good shape.
