Having trouble with my first built- power supply not working?

BAMFito · Mar 28, 2014

I been working in my first build.
I have connected the two main power sources to the motherboard, CPU and the shunkier one.
I am not getting any kind of response from the motherboard.
AM expecting for the motherboard to flash or something, but nothing.
am I doing something wrong? should I have something else plugged in to test it?
is my power supply dead or what?

AMD Radeon :

It's cheap, but it supports the FX-6300.
