Newly built PC powers off after 3 minutes...won't power back on instantly

I recently replaced my motherboard, processor, memory, and power supply. After powering up and running for approx. 3 minutes, the rig shuts down, like somebody pulled the cord out of the wall. It won't power back up either instantly. I have to wait a while before I can even turn it back on.

"I seem to be using this link a lot lately, but anyway:
http://educations.newegg.com/tool/psucalc/index.html
PSU calculator from newegg. Just pop your hardware into that and it should give you some idea as to whether or not the problem is your PSU."

"You say it's not heat but you only checked the CPU temperature.

What if the PSU was warming up and reached the point it was unable to deliver the needed power--from your comment to ThisTime it sounds like you're at the edge. So long as the power supply is too hot it can't deliver enough power and the board doesn't work.

Alternately, the PSU has an overtemp shutdown of it's own."
