Hello,
I have an Acer AX1700-U3700A desktop. The tower went completely dead. I installed a new equivelent power supply and still no power to tower at all. The power cord is not defective, all connections are in order, still no power at all to the tower. Could it be a defective power on button or bad motherboard.

Did you check the motherboard?
