    I got my new Mac Pro 2009 with great configuration for a very good price :)

    Now the only problem I've found is how to get molex adapter inside optical bay.

    I use a nice backplane for 6 SSD's but it requires a molex power connector. There was no problem inside Mac Pro 2006-2008 but now it's missing. Are there any converters from SATA power cable to molex ?

    I'm thinking of adding a 4x or 6x 2.5 backplane to my optical bay, too. OP, what backplane are you using? Does a 6x backplane leave enough room for an optical drive in the other slot? What card are you using for the additional SATA ports?

    More generally, should one be concerned about powering multiple drives (including a couple of spinning drives in my case) from a single SATA power cable?

    I use this:,chieftec-ctm-1062-s-sata.html

    I use ARECA ARC-1231ML + 2 GB Cache + BBU.

    Optical drive fits without any problems in Mac Pro 2008, didn't test in 2009 yet, but it's should be ok.

    I also found Mac Pro doesn't have that large gap between the optical drive bay and the main area, but I think all cables are no going around the optical bay so I hope I can put my SAS -> to 4xSATA cable there too.
