My thought is that yes your new power supply is defective. Check the
2 voltage outputs going into the mobo from the power supply with a
meter. If they are present then check the voltage input to each device
for the correct required voltages. If these are normal and you are still
unable to get device recognition then swap out the power supply for
another known good one. This should give you the answer you seek.
