View Full Version : Network Card for PowerMac G5

Oct 25, 2009, 03:59 PM
I have a PowerMac G5 with two gigabit network ports on it, but one of them has stopped working. I am wondering if I can just buy a PCI gigabit network card and plug it in to one of the open PCI slots. If so, can I buy any brand?

The one that is listed on OWC is like $90.

I have browsed through all of the ones on NewEgg and none of them mention support for Macs at all, much less a PowerMac G5. Will any generic PCI Gigabit card be supported?

Personally, I'd just use the other ethernet port until it also dies, likely by that time you would be looking at simply replacing the machine with something faster (like a Mini)

Been awhile since I've seen any news on which PCI ethernet cards work with the G5. Some did, and some people had problems with.

Edit: looking at that they have a rather old driver (http://www.sonnettech.com/support/kb/kb.php?cat=359&expand=&action=a3#a3), don't know if you still need their driver for it to work, or it was replaced by a generic Apple driver.

Might be able to buy a similar chipset for $15 and the local computer stone and use the sonnet driver also. Don't know with if it'll work with a newer chipset, but that used to be what some would do.

Presto Gigabit Driver Installation Steps
If you are using Mac OS X Version 10.2.x–10.3.x, this section covers the installation of software to support the Presto Gigabit. If you are using Mac OS X Version 10.4.x or later, you may skip this section; the driver is built in and your installation is complete.

Thanks for the info. The problem at this point is that I am using the PowerMac to run a DroboPro and am wanting two network ports so I can connect the DroboPro via gigabit rather than firewire.

A mini will probably replace the machine eventually, but if for a while I can spend only $15 to keep it going, that would be nice.

Koutech USB 2.0 + Gigabit Ethernet 10/100/1000 Combo PCI Card Model PC520 (http://www.newegg.com/Product/Product.aspx?Item=N82E16815201024&cm_re=PCI_ethernet_card-_-15-201-024-_-Product)
Rosewill RC-400 10/ 100/ 1000Mbps PCI V2.2, 32/64-bit, 33/66MHz Networking LAN Card (http://www.newegg.com/Product/Product.aspx?Item=N82E16833166002)

Both are inexpensive cards that are PCI and claim to run in OS X (10.9 +). But no specifics if they'll run in a G4/5 system at all. So I'd recommend checking out the product's page, and even fire off an email if needed. Worth the effort vs. $90USD for the Sonnet card IMO. ;)

Have you tried checking ebay?


Quite a few choices and are pretty cheap. Just stay away from anything that has a VIA chipset :D. There's even a dual gigabit card there so if your other ethernet port fails, you can still have 2. And it's only about half the price as the one you mentioned!

Do you have the dual-core version of the G5, those use PCIe cards. The ones above use PCI/PCI-X.

Note: If you follow some of the "other" cards using this chipset, they are of the $15 card variety.
