    What size PS comes on the 27", 3.06gig iMac?
    What is the power of the iMac PS, how many watts?
    I havent seen any mention of the Power Supply anywhere.

    It's build into the iMac. There is just the power cable.

    Ive had to change PS's on my PC's in the past. What would you have to do if the PS on an iMac dies?

    Get a three year warranty (to extend the already existing one year warranty) by Apple (Apple Care Protection Plan) within the first your of your iMac purchase.
    Then it gets replaced in the case of a failure.

    If not, hmmm, that might be difficult. But until then there might be some offerings.

    In the months I've been here, the PS was one of the least failing parts in iMacs if I recall correctly.

    I wouldn't really worry about it.

    I've either owned or known of literally dozens of Macs over the last couple of decades, and the number of power supplies being replaced is zero.

    The PS in the Mac is designed to be the right capacity for the Mac in question, plus some overhead, and it's of decent quality.

    What I see on the PC side are people who make their own boxes that underestimate the current draw and install a less expensive PS than needed, and over time that PS tends to fail. Or, they went for a cheap PS and it dies.
    This also happens when folks install a bigger graphics card and forget about the extra load there as well.

    If the PS fails on your Mac in the first year (again, unlikely), simply have it fixed under warranty. Applecare can be bought to extend the warranty past the normal expiration, but nicely enough, you don't have to buy Applecare right away, but you can wait the entire original warranty period to make up your mind.

    Thanks

    Thanks to you all.. I was just wondering, since I have read nothing about PS's on this forum.

    DougY,

    There were numerous reports of the Apple PS failure on the Time Capsule (mentioned on some other thread). Also, there were some speculations that the 27" Mac screen blackouts are somehow related to the PS malfunctioning (unconfirmed and unverified).

    yep and if you go way back then 2005 (and i think 2006) iMac G5's were sold with power supplies that did fail.

    That was due to bad capacitors - an industry problem - not specific to Apple.

    There was a warranty extension program but it wasn't that widely known - they didn't contact owners for example.
