I have one 2009 4.1 MPc.
UPDATED:
Machine keeps blowing fuses upon plugging it into socket for power. Once one fuse is blown (or fuse is blown one time) the machine runs just fine.
I now did have another look at the problem, and seems that the fuse will blow when cable is put in FIRST time...
In my previous post some people said that I should change the PSU from my PowerMac G5. My question: Is the AcBel 600 Watt PSU compatible with it? I am new to PowerMacs

My serial number is CK422H6MR5J . I looked it up on everymac.com and it says A1047 (EMC 1969) is my model name.
Hi guys!
I have here an cMP, a 1,1 - 2006 (flashed to a 2,1) Mac Pro.
Two days ago I left it powered on and a few hours later when I take back to work it's already off and since that moment can't made it powering on again.
No signal. No error leds, no sound, absolutely nothing.

I have a dual core early 2009 Mac pro.. I was working just fine till one day it just died over me. After tons of research I figured it was the PSU as the diagnostic LEDs were dead aswell so I gave the PSU to this mechanic I knew and he sort of fixed the issue (I Think) cause after the repair the...
I’ve got a 1080Ti (and a 980) added to my Mac Pro (4,1 upgraded 5690 CPUs to 5,1) using an external 750W power supply and it's working and now I think I need a SWEX so that I don’t have to turn on the power supply every time, and always have to shut down my Mac when I'm not using it for an...
Hi there, newbie here. I joined to post this thread. I've read through tons of threads here and learned a lot, and I've managed to get a 1080ti running in my 2009 MP 4,1 flashed to 5,1 with power from the built in connectors + a SATA port. It's working great! However, when it goes under VERY...
Hi,
Im working on a Mid 2010 iMac EMC 2389 that appears to have no power at all. The power button does nothing, and I have tried different outlets and power cables. My thoughts are the PSU.
Below is a picture of the PSU with some of the pins outlined to show what I am talking about.
I tested...
Experiencing intermittent shutdowns/power loss with a late 2015 5K iMac (i5 3.2ghz/M390/flash storage)
Haven't been doing anything GPU or CPU intense, it's happened at random times, and even when it's sat at the login screen. It won't turn back on immediately, had to pull the power cable a...
Good morning all,
Like a few others here I didn't check the power requirements before buying the 1080Ti for my Mac Pro 5,1, and have been scrambling to find a solution for powering it which doesn't involve a secondary PSU or overtaxing the 2x6pins.
I still have 1 PCIe slot available, and it...

Hi
The iMac stopped to work suddenly. It switches off and it is impossible to get anything running. No light, no sound, no life.
I opened the iMac and looked at the power supply. Is anyone experienced with the PSU repair and have some idea how to proceed in this repair. How to check if I...
