I am needing to replace my power supply in my iMac I think. Can anyone point me to a guide for that and a place to order the part? My situation is this. Over the summer, my comp crashed. Determined it was the hard drive. Replaced it. Up and running again, but since then I have noticed the power supply running extremely hot. Gets up to 93º C under light loads, with fans at full speed. I presume the heat is why my hard drive crashed. Any feedback on the situation?
Hello! Have you run Apple Hardware Test yet on the machine? This test is included on one of the DVDs that came with your computer. This may help further diagnose. However the power supply certainly shouldn’t be that hot!!! iFixit does not yet have a guide for this machine. You can use the guide for the 20" counterpart to get where you need to go. The part you need depends on your machine. If you do not know which machine you have, check out the ID Your Mac page. If you have a 2.4 or 2.8 GHz (EMC 2134), your part number is 661-4478. If you have a 2.8 or 3.06 GHz (EMC 2211), your part number is 661-4665. Plug these numbers into the search box in the upper right corner of Apple Palace to find your part! I hope this helps!
The overheating of the power unit in your iMac is due to overload from other units. Since Hard disk has been replaced possible Processors are about to call it a day. Good luck, SAO
