    I've got two hard drives mounted in the lower optical bay of my 2008 mac pro. I have a 4-pin molex to two 15-pin SATA cable. Looks like this. My mac pro is open with the optical bay out and the two new SATA hard drives mounted with an OWC multimount. The 4 hard drive bays have been removed. I can see the ODD_SATA connectors on the logic board (and I have two SATA cables ready to attach), but where on the logic board do I connect the 4-pin molex connector to get power to the optical bay drives? I think I'm missing an adapter. Am I?

    Thanks.

    molex

    If it's an '08 MP, you should see a molex connector in-line, meant to be used if a 2nd optical drive was installed in the lower optical drive bay, on the same cable that powers the top optical drive.

    That's what I used, putting 2 ssd's in the empty bay, along with the spare sata ports on the mother board.

    RP, thank you.

    I'm a complete moron. Once I removed the optical bay drive cage, I tucked the PATA cable back inside the cavity so that I could see the guts of the logic board and..well...just didn't notice that second power connector. Feeling pretty stupid right now. I mean, I have the fan assembly pulled out and everything :D.

    Thanks again. I can complete my SSD upgrade now.

    Okay, I'm on a roll tonight. You have to remove the fan assembly to facilitate getting to the ODD_SATA connectors. Gonna log off now before I say something else stupid.
