Test it. Unplug the molex connector from the mothrboard. You can use a wire or a paper clip to test it to power on. You will connect (short) pin 14 to and ground pin. (diagram here) For example, put one end of the paper clip into pin 14, and the other end into 13, 15, or 16. If the power supply turns on and fan running then maybe a problem with the front panel switch on the computer case.
P.S. make sure you unplug all other leads to drives before doing this.

And what might the problem be?

I don't understand the question! Maybe Black, White, Green. I do not quite understand what you need to know.

For 120 volt operation use black for the hot, White for the natural, Green for earth ground. For 240 volt operation use; Black and White for the 240 volt and Green for earth ground. Black is generally designated as the "Hot" or "positive" . You must make sure the switch on the power supply is set for the voltage you are using. ie: 120/240

Recheck all your board connections. I missed a connector by one pin and got nothing as you have. Once I realized my mistake and re connected the plug on to the board correctly everything worked.
