    I have 5 internal harddrives and 4 external drives
    connected to my Mac Pro.
    Are there going to be any power issues with having so many harddrives
    connected ??

    It must take alot of power to drive all the drives.....?

    I'd say there will be issues on the bus, but I don't know about power. It does havea 1000W power supply.

    Yeah, bus issues is what I was thinking too. There shouldn't be a problem unless you're thinking of using a bunch of them at once (Which you very well might be if they're all scratch disks/render storage). But, yeah, no power issues are overly likely. It's more like possible slow or maybe even unreliable transfers between them if you use a bunch of them at once.

    If the setup seems to be working fine for you, you should be good. That crazy power supply should take care of most of your worries.

    Hard drives won't be overloading the Power Supply.

    This thing was designed to run with 4 Graphics Cards and 4+ hard drives.

    You can get 6 SATA drives in fairly easy plus 2 IDE in the Optical Bay if your really crazy.

    Maybe this would be useful to your project.

    You can also switch to a bigger capacity drive to reduce the drives. It must create a lot of noise and heat with all those drives.

    Basically each hard drive would take about 1% of the available power. I'm not even sure if it's possible to overload that power supply with legitimate computer parts that would actually fit inside the case.

    There are mount locations for six drives, four SATA and two IDE. You can get up to 750GB in IDE drives. You can use the two extra SATA ports in place of the IDE, but you need to do some disassembly so you can use a cable to connect the SATA connector under the front fan housing up to the optical bays.
