2 port firewire pci card for g5

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.

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

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.

thanks
mike
