New build not firing up - what to check before RMA MB

Row1

Hi, y'all - I just assembled a regular ATX computer. when I press the "on" button, the fans start up for a couple seconds, then cease to keep going. I get no beep code at all. The MB does not have its own light, like some have. I have checked all connections. I let it set for a while wondering if capacitors need time to juice up a little. I have a pci-e videocard along with everything else, so there should be enough of a load on this 450 watt PSU.

What can I check before RMA motherboard? I wold love to find one little thing I have overlooked.
 
OK - I figured out the one connection that was not in all the way. No worries.

Now, on to the next problem.
