I just downloaded and had a look at your motherboard's manual, and didn't see anything about LED lights on your board. Most boards (especially newer ones like yours) have troublshooting LED lights to tell you that the board is getting power from the PSU, or if it has troubles with the graphics card etc.
Just to confirm, take a look at your motherboard and confirm that there actually ARE some LED lights on the board somewhere. If your board has LED lights, and they are not turning on when the PSU is connected, then you have a dead board.
Nice case by the way. I have the same one, and love it!
