>why does it need a slim cable? Besides aesthetics and ease of integration in the chassis, air flow / cooling is a non-trivial issue, particularly with the wattages systems are running now. More or wider cables increase chassis air flow impedance which requires higher pressure fans to overcome which translates to a louder overall system.
