Apple: Power Mac G5 Repair Extension Program for Power Supply Issues

The Power Mac G5 Repair Extension Program for Power Supply Issues applies to Power Mac G5 systems that have power-related issues as a result of a specific component failure within the computer’s power supply. If your Power Mac G5 fails to start up after the power button has been pressed and your computer’s serial number is within the noted ranges, your computer may be eligible for repair, free of charge. There are no known safety issues caused by this component failure.

The affected Power Mac G5 models were sold between approximately October 2005 and August 2006 and feature Dual 2GHz, Dual 2.3GHz or Quad 2.5GHz PowerPC G5 processors.

If Apple or an Apple Authorized Service Provider (AASP) determines that your Power Mac G5 computer is eligible as part of the program, the power supply repair will be covered by Apple for up to two years from the original date of purchase even if your Power Mac G5 is out of warranty. This worldwide Apple program does not extend the standard warranty coverage of the Power Mac G5.

Affected systems will exhibit one of the following power-related symptoms:
• System will not start up after the power button is pressed
• No LED activity
Note: If your Power Mac G5 is not experiencing any of these symptoms, you do not have to contact Apple or any Apple Authorized Service Provider.

The affected Power Mac G5 computers have serial numbers where the first 5 digits fall into the ranges noted below. The Power Mac G5 computer’s serial number is located inside the case directly below the air deflector, along with other configuration information.

Serial Number Ranges:
• CK539xxxxxx – CK608xxxxxx
• G8539xxxxxx – G8608xxxxxx
• YM539xxxxxx – YM608xxxxxx
• RM539xxxxxx – RM608xxxxxx

  1. This is certainly not unexpected, given my experience.

    I purchased a PowerMac Quad G5 in December 2005 and this problem has bitten me big time. Apple has had to replace the power supply two times, and the motherboard once.

    About three months ago I talked to an Apple Tech and he confirmed that power supply problems were rampant on these models. I have AppleCare on my machine, but it is nice to see that Apple is going to extend coverage for this issue to everyone affected, including reimbursement those who may have had to pay for out-of-warranty repairs.

    This Macintouch thread covers the issue exhaustively:

    MW: ‘who’ (can it beeeee now?)

  3. What’s up with Apple’s quality these days? Can they release any model without a repair programme six months later? OS X is great, and the visual design is still in a class of its own. But quality seems to be slipping the way of Dell and other PC manufacturers. I guess competitive pricing comes at a cost.

  4. Apple is like any other hardware maker, occassionally something goes wrong and they fix it.

    The PowerMac G5 has had plenty of power supply issues, from beeping to exploding capacitors to issues like this one.

    Now what Apple should have done when the power supply issues first started appearing in the earliest Dual 2 Ghz and Dual 1.8 Ghz models is fixed the design flaw problem in the Dual Core PowerMac’s. Unfortunatly they didn’t, they continued to bury the power supply in the bottom of the machine where it’s hard to get at and easier for mistakes to slip by.

    Now with the redesign of the Mac Pro, the power supply is at the top of the machine, where it’s easy to exchange.

    Unfortunatly the Mac Pro doesn’t look all that attractive with the case cover removed.

  5. My Quad has been in the shop for 4 weeks and when I was on the phone yesterday the girl put me on hold and then came back with the power supply update. Now they are going to hold it for another week and then repair that too. Seems that it takes longer and longer to fix these newer machines.

  6. I bought my G5 Quad this past January and I have had no problem with the power supply as described above.

    Quality issues, just as good as always!

    Point of note: Always buy AppleCare with your Macintosh, you might not need to call on it and should you do have to its there as a safety net.

    Even those Macs you helped a friend or family member buy, ensure it has AppleCare so should it go wrong you won’t be the one they’ll bug you to get it fixed.

    My 2 cents worth.

  7. I also must chime in with both some perspective and personal experience.

    I think most Macs are durable and even these ‘widespread’ issues affect – in terms of overall percentages – fewer individuals than it may seem compared to the total population of G5 Quad owners.

    I have had no problems with my Quad apart from some dust which got in the optical drive while on location. The Mac Genius at the Apple Store swapped it on the spot, no problem.

    And the same week, I received my second free battery from Apple for my PowerBook G4 1.67. So I now have three batteries, but am still using the first, supposedly defective battery. Am I to guess I am the exception here, too?

    Last weekend I purchased a MacBook Pro for my son. I got the AppleCare – just in case. I hope you did too.

  8. I am a Mac specialist at a major design college in NYC. My failure rate for first gen iMac is fast approaching FORTY percent. Industry average is 4-6%, correct?

    Apple, LISTEN THE F**K UP! STOP THE QC NIGHTMARE. I am fighting upstream trying to convince administration that Mac hardware doesn’t have endemic hardware issues. I lose a little more groung with every failed machine.

  9. “occassionally something goes wrong and they fix it.”

    With just about every model something goes wrong. it’d be better if Apple engineers could go back to engineer school to learn to design hardware properly rather than fix it afterwards.
