Computer won't turn on at all.

First things first here is my build. (Win 8.1 installed)

I just got this thing put together and running great last week. I was so excited that everything came together with minimal problems. I did a test run in Heroes of the Storm and it performed great and CPU temp never got higher than 53C.

So I just got my WiFi receiver in the mail today and wanted to set that up for game night tomorrow, but then suddenly the whole thing shut down a few minutes after turning it on. No noises, no blue screen just dead. If I press the power button the light is off before i can even release the button again. The fans get a very quick pulse of power too. No beeps at all. Any guesses what might be wrong? I tried one stick of RAM at a time and also tried swapping the reset and power switches (saw it in a different thread while searching for help). No change in results. My best guess would be either PSU or Motherboard, but I wanted to post here before I start trying to claim warranties or anything.

PSU has to be the top suspect.

I had the same guess. I went ahead and asked Amazon for a replacement, (side note amazon support is awesome) and it has not solved my problem, so I went ahead and left it with the old supply since it was still zip tied to the case. Interestingly enough, The computer now lets the lights and fans stay on, but no sign of life from usb or display. I guess it is time to blame the motherboard. Still no beeps.
