New build turns on for split second, then nothing

So... new build, first time, all put together, the system will light up for a split second when I push the power button then won't stay on. All connections solid. Any tips? I haven't tested the psu yet. Maybe I'm missing some connection?
Here are the specs:
antec 300 case
gigabyte Z68XP-UD3
i5 2500k
corsair 600 psu
corsair 8 gb memory
cooler master 212
generic sony dvd
rosewill card reader
samsung ssd
no video card yet, still on the fence.
The mobo was a like new open box on amazon. Everything else is new.

  1. Just checked power supply, doing the green line in the 24 pin connector trick. Power supply fan spins (not super fast).
    Touched the power switch together with a paper clip. Did the same thing as the case power switch. Quick on followed by nothing
    I'm thinking mother board. Am I heading in the right direction?
