Frequently Asked Questions About Apple iMac Repairs

01. Why are there different Apple iMac G5 PowerPC MOB capacitor kits available for sale?

There are two different types of motherboards used in the earlier Apple iMac G5 computers. The early 17 and 20 iMac G5 PPC models used a total of 20 capacitors of one type and 5 of the other type. Whereas, late model, newer Apple iMac G5 PPC computers require 24 capacitors of one type and 5 of the other type. Hence, the difference in the total amounts required for each kit. Also included are some other iMac capacitor kits for later versions of the G4 and G5 computers. Notes: All capacitors are brand new, low ESR, high temperature rated (105 degree C), motherboard grade and switching power supply grade ratings. All iMac G5 MOB capacitors are the exact diameters and heights (10mm X 16mm) originally installed on the iMac G5 mother boards. Please verify the total number of capacitors in your iMac before making a purchase. Once shipped, all sales are final.

02. Power Supply Question: Why are there so many different Apple iMac G5 PowerPC PSU capacitor kits available for sale?
Apple contracted out to a number of power supply manufacturers for different model power supply units to be built. As such, there are different capacitor kits for each of the different model power supply units. Please verify which iMac G5 model power supply you have in your iMac before making an online purchase. Once shipped, all sales are final.

03. Help, I don't see my power supply listed or my iMac G5 MOB is different; what can I do?
If your power supply unit does not match to what you see in the Apple iMac G5 PSU Comparisons page, please contact me. Also note that due to the differences in configurations of the various power supplies, the best way to match your type is to do a visual comparison and not by part number. If your iMac G5 motherboard does not seem to match what you see in the online MOB documentation, you may have a newer model iMac G5 iSight model or an Intel based Apple iMac G5 Model. The procedures for MOB removal and repair are different on the newer Apple iMac models.

04. What tools do I need for capacitor removal and installation?
Please read in detail the complete how-to guide for capacitor replacements. Please read over the Apple iMac G5 early models procedure for disassembly and capacitor replacement of Revison "A" and "B" models. Also, it is a good idea to read the details of the iMac G5 Mother Board Repairs and the iMac G5 PSU Repairs procedures for additional insights and comments. The number one basic tool required is a good quality, wide tip, high wattage, quick heat recovery, soldering iron. Once again, I need to reemphasize the need to carefully read over the entire procedure before you decide if this is something you want to tackle. I highly recommend the 12-in-1 screwdriver. This screwdriver has all the various small Torx tips required for disassembly of the Apple G5 Computers.

05. How long does the Apple iMac MOB repair and capacitors installation procedure take?
Replacing the capacitors on the mother board depends on your experience level on working with electronics. I would suggest planning on three to five hours of time for the MOB repair procedure to completely remove all the major internal components, including the power supply, hard drive, super drive, memory, and of course the motherboard. and then to replace capacitors, and finally reassemble the internal components. The amount of time required for the PSU repairs are typically shorter. Take your time to do it right; do not rush the project. Please refer to the online procedure posted at: How to Repair an Apple iMac G5 Computer.

06. Will you repair my Apple iMac G5 for me?
At this time, due to my busy schedule, I am not repairing other iMacs. This might change in the future, but for now, I can only provide email support.

07. How old are the capacitors, and do you guarantee the capacitors?
I guarantee all capacitors are brand new, fresh from the factory floor, and are the values, ratings, sizes, and quality that Sanyo provides me with. Sorry, I can not take back unused capacitors.
