Winfast MB no post

I just got this winfast761GXK8MC 10 days ago and cannot get any post, beeps
or video. I have tried two different CPU's an amd 3400 and Septron 2600.
Also have tried two PS one 350 watt and one 450W. The ram is new and worked
in then other MB I had. My concern is where the PS connects to the board the
connector does not cover the whole insert. There are 4 pins left open. Do I
need a different kind of PS for this board? Also I get 00 error on the post
up card if that means anything.

Thanks,

Brian
