And what kind of fuse does it take. Or is it just better to buy a refurbished one. And by the way, I didn't find it all that hard to take everything out, I used the fixit site and that seemed to help.

The power cuts out after short periods of time, sometimes 5 minutes, sometimes up to half an hour. The apple display color is distorted with a purple tint but with a HDTV plugged into the other slot the image is perfect. Not sure if PSU or videocard. Any ideas?

It's not highly simple to get it out, but you can do it yourself with some patience and complete information. I had a tech manual pdf on how to do it, but they even left out a couple of important things which I figured out on my own, but not easily. Like you need to take out the bottom two torx screws from the screwstands after removing the bottom processor, even though the instructions say to leave them all in; and foreward-most cable connecting the PSU to the motherboard needs to be pushed as far forward as possible with the PSU while angling it out. There is really no extra millimeter of space to remove the thing without these two steps. Anyway, I was really happy that I found a relatively inexpensive replacement PSU, though it took two weeks to arrive, but then after only a few hours of happiness, the G5 just shut down while I was working and restarted automatically. Anyone else have this problem, and/or know what the causes/solutions might be? Thanks in advance, Keith I just replaced my PSU myself this morning (Mac G5 dual 1.8).

I was desperately looking for this. I have a problem with the fans on the PSU. They make noisy weird sound wich drives me crazy after a while so I have to replace them. This manual helps me with this I hope. Thanks from the Netherlands to you all bloggers. Great website! dinosaur41 Thanks Andy for the link to the Service Source PDF.

Apple retailer said its outside the 3year extended service fix. I got the excellent instructions for dismantling the mac and dont think i'll have any problems there. I also have G5PM dual core that is dead with a fried processor i think. Can i use the dual core PSU and put it in the Quad core? I know the quad has to have 1kw but i dont know yet whats in the dual core. I have a feeling its no good as the power cables are different. The quad has the newer square female plug and the dual has the older style with the 45deg corners if you know what i mean. I was hoping this would save me buying any parts and i can get one good mac out of two door stops. any advice I have a G5 powermac 2.5ghz quad core with a dead psu.

The fans all come on but the light on the power button blinks 3 times indicating bad RAM and I get the message 'No Signal' on the VDU screen. Anyone have any idea if it is the PSU or the logic board that is at fault. The covers of the processors are secured with four plastic clips which you can either push the cover in one direction to unclip or slide in a flat bladed screw driver and gently push the clip to release it. Be very careful as they break very easily. I too have a G5 powermac twin core 2Ghz which refuses to boot.

It's great that you found it though! There are tons of youtube videos on how to tear apart laptops but I am struggling trying to find any serious service info on G5's!
