I've just got the final parts for my new rig today and quite embarrassingly I'm stuck more or less at the first hurdle 
So, I've got 2x6 pin headers on the 1Gb HIS 4870 and all I want to know is which do I plug into my PSU? Both or just one of them (and if so, which)? I go the OEM version so no distructions with it sadly.
This should take someone in the know about 5 seconds to answer but any help is appreciated.
Thanks
