has anybody successfuly added extra firewire ports on a g5 powermac? i have a dual 2.0 ghz mac purchased late 2005 and understand i need to use a pci express card but so far as i can see on the web, no cards are compatble however I have a siig 2 port firewire pcie card that on the manufacturers site says that it does.... the box and manual pdf state it doesn't though.

thanks in advance for any help D

g5 power mac late 2005, Mac OS X (10.4.3)

    I believe PCI-X Slots are backwards compatible with PCI Cards, so any FW card that's Mac compatible should work. I use the adaptec FireConnect card, and it works fine.

    It's PCI-Express, like in the new MacPros that ISN'T backwards compatible.

    Hope that helped!

    Hi daryll;

    I have a late 2005 G5 and it has PCIe or PCI-Express expansion slots. These are not compatible with PCI or PCIx.

    Scratch that. Mine is Early 2005, and that's why it works -- my slots are still PCI. Had to go back to the spec sheets again.

    I wouldn't try putting it in yours -- don't want to fry your board or anything.

    Did you try OtherWorldComputing or SmallDog Electronics -- may of the places that specialize in Mac gear should have something...PCI Express isn't exactly new anymore!

    Sorry about that, and good luck.

    thanks for the help guys though I'm not there yet.. am gonna go check the sites kwamster mentioned.

    I checked my spec sheet and my mac has 3 pci express expansion slots though the genius at the apple store told me to go for the tango 2.o firewire card... even though it's pci?

    adios u's D

    Yeah, OWC has some PCI-Express cards that add additional FireWire and USB ports.

    Hi Allan, what does that mean?... are there firewire port expansion cards for my mac or are they like the proverbial rocking horse s$@t?

    Hi Daryll;

    As Steve said above OWC has expansion card for PCIe.

    So The Siig firewire 2-port PCIe product # (NN-E20012-S2) will not work in a quad core G5? I hadtalked to a salesman at Siig and he said it would. I ordered the product and the box does not say one word about Mac. I'm kinda apprehensive about putting it in my computer. besides that I don't see antywhere on the mac to bug the power source into. If anyone has sucessfully got this card to work in their Mac, plaease let me know.

    also I checked out the OWC site but they do not offer a firewire 400 solution in the PCI Ecpress format. Is it possible that there is not acard that will workwithmy computer? I've been searching for the past week and a half for a stright answer. no one seems to have one.
