Refer to the list of Apple iMac G5 Power Supplies with detailed pictures and capacitor upgrade replacement comparisons. Make sure you verify which Apple iMac G5 power supply you have.
Capacitors are all high quality, switching power supply grade, low ESR, and long life ratings. The 3300uf cap has the longest life. Upgrade notice: Because of the difficulty in obtaining 10mm X 30mm 3300uf 10 Volts rated capacitors, I have upgraded this to the 12.5mm X 20mm 10 Volts rated capacitor. These 3300uf capacitors will fit into the space on the PSUs, but will stand above the circuit board slightly because of other components in the way at the base of the larger diameter capacitor. Note, the original 3300uf capacitors in my opinion were standing too high and shorting out on the top of the metal power supply cover as can be seen in the original trouble shooting section of the Apple iMac G5 Power Supply repair article. Additionally, the 1000uF 25 Volts rated has been upgraded to the 35 Volts rated cap and is now 12.5mm X 20mm in height too. This caps have a significantly longer life rating than the originals, and will fit inside the case with no problems. The case actually has approximately 31mm height capabilities from the top of the printed circuit board to the inside of the metal cover. Note also, that some of the capacitors have been upgraded in voltage ratings. This was done as a matter of choice, in that a higher voltage is not necessarily required in the power supply, but where appropriate sizes were available in higher voltage ratings, I made the upgrade substitutions for extended performance and life expectancies.
Include withe the order is a replacement chart showing the original value capacitor and the replacement value capacitor with your PSU cap order. Please refer to this chart when installing the new caps.
Be sure to double check your motherboard capacitors too. Purchase both the MOB and PSU caps at the same time and save on shipping costs.
