How did you test the power supply? With a tester designed to test ATX supplies?

This sounds like a defective power supply but if you are sure it's good then yes, the motherboard is likely bad.

It's also possible that the CPU chip has blown. I recommend you have atech look at it. They will have parts they can swap in to located the defective part.
