yeah, long day and coffee was wearing off, i did mean bus powered. sorry for the slip.

was going to try and borrow a powered firewire drive to try, but looks like the post above beat me to it. glad to know it works! i also thought about just adding in a PCI firewire card if i ever needed it.

power supplies; i use a lot of THESE and love them. lots of stable power, really quiet, 80plus means less power is turned into heat, etc.

of course, pictures of your build will be required, but you probably already knew that. best of luck.

I was just thinking of doing the very same thing. With this setup, is it possible to replace the Apple power supply with a stronger quieter one? Or is the power supply proprietary.

Hi

A standard PC ATX Power Supply does not have 28V DC and will not be pin compatible with the Gigabit G4 and later G4 systems. I wanted to clearly note the ADC/28V issue for anyone thinking of using a standard PC ATX supply for a conversion with the summer 2000 and later G4 systems. For all but the Mirrored Drive Door G4s (which use a non-standard form factor power supply) - the original Mac Power Supply will fit in most ATX cases, if the cable(s) will reach the motherboard of course just use your original Mac P.S. (You can sometimes find Gigabit/Digital Audio and Quicksilver Power Supplies for sale at Ebay if your PS has failed.)-Mike

If you want more detail so join me

It doesn't need to be bigger, but have more power. So look at different power supplies specs.
I would recommend to look for x5 as more power as the original unit. That wouldn't be easy to find though.

Are you talking about the X5 power unit? It is well hard to find! I had a simular problem myself, I found loads of information on the net. I managed to get one in the end from some American site, check out the link it may help you! If not you can always try ebay!

I really don't have anything to add to this post. At this point just a spectator learning about macs. So, far only using pc's but have friends that have a mac notebook for each family member and they love them.

It appears the original poster re "G4 to ATX conversion" has received nice informative responses. I am impressed with this forum!

I've been trying to put a flashed GeForce 3 in my Sawtooth Gigabit G4 but I'm getting the same flickering image problem most people that have tried this have had. The problem is that the card doesn't draw enough power, which is not surprising since the PSU in the G4 is only about 200W. So I'm thinking about replacing the PSU with a new ATX PSU. However, the only conversion scheme I've been able to find is for pre-gigabit sawtooths (the ones that don't have +28V DC required for the ADC connector).

I am currently learning about Macs also, I have heard they are good machines but looking at this post seems like they are well looked upon. This topic seems to have a number of quality reply to the original problem, Ill be sure to make some topics on this forum if i have any issues with a Mac if i get round to buying one.

Hope your problem is resolved.

I am also looking into the G4 mirror door mac conversion for better and more stable power but little confused on the pin outs. There people out there that completed this conversion with minor issues but really wandering if the time for it is worth it. I also finding people have take G5 tower power supplies able do the same wandering what is the best option for me. Would like to do other mod to this machine besides adding power supply.
