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 has the longest life at 10,000 hrs. rating. 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. 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.
Be sure to double check your mother board capacitors too. Purchase both the MOB and PSU caps, and save on shipping costs.
Add the handy 12 in 1 multifunction torx screwdriver to your order too.
