Hi. I have a question for you guys. I just purchased a PCI-Express e-SATA card for my 2008 mac pro 8 cores and i'm wondering if i have to connect it to one of the two connectors on the motherboard or do i simply slide in the card? The reason i'm asking is that the connector cable where not provided with the card and it says optional on the package. Thank you in advance for your help. Yvon.
