I know that with a little modification one can put a PC power supply inside a G4 powermac. I know that this had been done quite a bit with the Sawtooth models. Are there any other G4 models that this will work with? I know Apple change their "power" scheme a tad over time, but I just don't remember what they did and what kind of effect it had.

You might have seen my modification to a PC Power Supply for a Quicksilver, I think it's similar or the same for all G4s. What version do you have and would you like me to email you a copy of the PDF I made?

krillbee · Jan 27, 2008, 06:58 PM

Well I don't have it yet, I am thinking about making my own "franken-mac" and the board I buy will be partially based on compatibility issues with PC power supplies.
Sure the PDF would be great

I'll PM you my email address.

Haha, ok, well I hope it helps anyway

That's a very impressive write up! Has that been posted on the web yet, like on sites like xlr8yourmac? I did a search earlier and all I could find was information for the sawtooth ps mod.

Also, I wonder what the digital audio and gigabit ethernet mods look like. Maybe they are the same as sawtooth? I have no idea

Well a Digital Audio should be similar, it just lacks the 4 pin connector for the CPU.

I haven't posted it anywhere except here, I can't remember if I created a thread or just posted about it in the PowerMac forum.

Gig-E has just two extra pins, and if you can live without adc and bus powered firewire you can rig it to run off a standard atx supply. I'm actually running my Gig-E off a modded sawtooth supply.

could you send me your quicksilver power supply mod?
Thanks,
Tod

Guys, I've attached the PDF to this thread, let me know how it turns out.

milhouse · Jul 13, 2008, 01:53 PM

Don't see a pdf attachment.

Which post?

seanc · Jul 13, 2008, 01:55 PM

OK., whoops, it doesn't work. PM me with your email address and I'll send it over to you.

Template attachment code fixed.

You guys need to report bugs like this in Feedback. I only ran across this thread by chance.

I only noticed today, I usually browse the forums in a different way.

Have you checked out this site for info on converting powersupplies?

That is a good reference link. If my Sawtooth PS dies, that link could save a lot of cash & allow a more efficient / quieter PS to be installed. Thanks for posting it.
