Apple Imac 27″ Mid 2010 Power Supply Issue

by on Mar.02, 2016, under STUFF!!!!

Well, it has been a long time sense I last posted. My Life in the big Oil/Gas industry has been busy.

But along this journey my old mac decided to shut down when ever it decided and did it randomly and then it just played dead.

I did not want to spend the money on taking it to the Apple Store for them to charge me $250 dollars to tell me what I already new…it is to old and I should buy a new one. ( I am to cheap and I am not spending 3 grand on a computer ever again!!!!)

So I started down the road of figuring out what was wrong. I figured either it was my logic board or power supply. I then called Apple and asked what it would cost for either or both. The scary part is I actually pricing and someone was going to ship them to me. How ever as soon as they figured out that I was not a Apple Store that stopped in it’s tracks pretty dam fast.

I did learn that the pricing on the Chinese sites and the Apple Store are not that far apart. Which is good.

To continue the story I decided to start with the cheaper of the two items and bought a power supply. Now you may ask where I bought it from??? I just used Amazon.com and found a supplier that would ship to Canada. After that, made my order and waited 6 weeks.

When I received the power supply and ripped apart my mac, I found the power I just received was the exact same as the one in it….right down to the silk screening on both the boards.

Installed and reassembled my mac and crossed my fingers…..it started and has been working for a month now with no shut downs or over heating or the worst…..electrical shocks!!!!

So for the short version…if you get a shock from your keyboard or the case and/or your system shuts down randomly…get a new power supply. The main isolation capacitors have failed. You can try and replace them, but they are not cheap. (they are a low resistance, high frequency capacitor)

Other thing I noticed: Power Supply 10-30 degrees C higher temps then usual. (Run a Fan control and temperature monitoring software. At present using- Crystalidea.com ‘s Fan Control)


Till next time, thanks for your time.
