Apollo arrived by Fed Ex two days earlier than expected.  Is up and running fine so far, but I have one question.
I am using a Seasonic Focus 550W PSU.  There are 2 6-pin PCI-E connectors on the cable that plugs into the PSU and there are 2 sockets on the Apollo, but when I first started it up I wasn't sure if both should be connected so used only one of them and it worked fine.  I now have both plugged in and it still works fine.  Question is, does it need both connected and if not why are there two sockets?
Thanks for the prompt shipping and Apollo looks great!
