OK I see I've got 2 6 pin connectors free (P7 and P8) so I should be fine with the video card. Any idea on the SATA power? I have one free SATA type connector P3 (same as going into HD) but it has 2 rows of 5 wires. The power going to existing HD has 1 row of 5 wires. Does this mean I can use a Y splitter to get more SATA power connectors?
Same with connector to optical drive, it has 2 rows of 5 wires, can I split that as well?
