If your case has a front panel built it im sure the cables are in the case. Usually they are grey and have black connectors on the end. You'll notive theyll say realtec, or hd audio something of that sort. The cables would connect onto the front end of the sound card if you at the picture of the sound card, or atelast they SHOULD. Front panel audio connectors are built into the case connections so look up inside your case where you power button connctor is coming from.
