What is strange is that I had the exact same problem so I returned all the products thinking something was defective....now the exact same problem.....something possibly is not compatible. Symptoms appear to be a short but I dont think it is. I carefully put all motherboard off sets from the case and did not overtighten any screws. When the power goes off and on....everything lights up....fans kick on....led's light up.....then bam off for about 1 second on for like 4 then off for 1 .....happens again and again......
2) Graphics card is receiving power because I see the lights.....but monitor remains black. Mointor will not detect the card whatsoever. I checked the obvious power to the monitor..etc...etc...
Im a one desperate frustrated NOOB! I want to diagnose this power issue first.

I have had this problem a couple times. Most likely as it is stated there is a short in your build Do not be alarmed becuase all that means is that you are not properly grounded in one place. I had this problem and i switched out my case and bam worked. Are you using brass stand-off's for your motherboard? This helps stop shorts by grounding it much better.
Considering you sent all parts back already this is the most likely problem. Start your computer with everything out of the case. Lay the mobo on a cardboard box and have the case real close to it. Connect everything that is need right on the box and try to start it up.
