The same thing happened to me on my first build, the problem for me was my CPU arrow wasn't lined up with the little arrow on the socket on the mobo.
editied my reply post Hale 90 650W
Fixed the problem. I was thinking it was something to do with my psu so looked at all my cables and I had 2 not connected. It's a mistake for a first timer. thanks again guys for trying to help
