| Replacement power adaptor for Apple Studio Display (Graphite) (Rev. C) |
Posted by: Corgi on 2022-11-11 03:39:48
I have a Graphite Rev. C Apple Studio Display with no power adaptor. For the life of me, I cannot find a replacement, nor the specifications of what it would need. I have a universal power adaptor that seems to fit the jack, but I don't know the required voltage nor amperage. I can't even find the Apple part number for a genuine replacement from somewhere like eBay or UsedMac.
I found a Rev. A on eBay that has a decent photo of its power adaptor, but it has the model code M4551 (obviously), not M7612, and I don't know if they'd be compatible. It's a standard 45W, 24V, 1.875A and my universal could definitely put that out.
Does anyone know what sort of power a Rev. C would need? |

Here’s the technical PDF which doesn’t answer your question but does make reference to a 35W power requirement. It may be helpful for you in other ways though

Did you ever get this sorted out? |

I have a rev A and a rev B and their power adapters appear to be interchangeable. However rev C differs more from the others than rev A from rev B… |

I tore my blueberry model down to replace the capacitors recently (too valuable to take a chance on 90s electrolytics IMO) and toned out the power cable while I was at it. It is center pin positive, if anyone wants to know. 24v and 45w appear to be the power requirements. |

For what it's worth, can confirm rev A and B are interchangeable. If rev C is the same voltage and amps, you could make your own using an old iBook power adapter as long as you can find a suitable female plug end. I did this for a few months while waiting to find an original adapter for sale at a reasonable price, and it worked great! |

I have a Rev. A I think (is that the one with the bondi-colored plastics that look similar to the Rev. A and B iMac?), and while it worked last time I tried it, it needed a new backlight (it was bright pink, a telltale sign of impending failure). Now it probably needs new caps too.
*sigh* This hobby isn't always the most fun, is it?
