    My PSU finally came back. I connected my RAM, graphics card, HDD, and PSU to the motherboard. My CPU and fan were already connected. I pressed the power button on the motherboard and got the same response (The CPU fan budged, but nothing else).

    I disconnected the 8-pin EATX12V and then pressed the power button on the motherboard. This ran the CPU fan and graphics card fans, and illuminated a light on the motherboard.

    So, I have now replaced the motherboard AND the PSU, and I am no farther along in this trouble shoot than before.

    Here is a video of what is going on ...

    Is my only option now that the CPU is bad? Is it possible that a bad CPU would block the board from pushing power through when the 8-pin is connected? Is this why the motherboard pushes power through when the 8-pin is removed?

    I did some more troubleshooting with ASUS tech support. They said its possible the replacement MB they gave me was defective and suggested I do another RMA.

    Well, since I have already replaced the MB and the PSU, the only two remaining constants have been the CPU and the RAM. The RAM has a lifetime warranty, so I think I might start there and RMA that first.

    Should I RMA the motherboard at the same time, or hope it is just a defective batch of RAM?
