I have found http://support.apple.com/kb/sp589 and http://www.everymac.com/systems/app...pro-quad-core-2.8-mid-2010-nehalem-specs.html but still lacking the info I need. Specifically I'd like to know what wattage and ampage SATA provides. I have seen a few of these cables which turn 2 x SATA connections into an 8-PIN PCI-e power. e.g. http://eu.startech.com/Cables/Compu...s-Video-Card-Power-Cable-Adapter~SATPCIEX8ADP and therefor negating the need for a addon PSU. But I have also read to be careful about ampage from SATA, but I believe this comment was in reference to somebody only using 1 x SATA port for the power, not 2 like the above link. Anybody know more about this or where I can look?
