MAC EMAC G4 & IMAC G5 power supplies

I am looking to find the specs on the power supplies for some MAC G4 and G5s. I am having trouble finding the wattage. Any suggestions?

    Thanks but unfortunately the wattage on the power supply is for the maximum DC output. The AC input will can vary based on the computer's performance. I need a to measure the AC input to the power supply to some system so I can measure how cost effective replacing them would be.

  • Scott Calafiore May 08, 2008

    Thanks, yes the voltage should remain fairly consistant usually servers are rated to handle 100-120v on US electrical systems. But the amps may seem to vary especially while the system is idle or in a power saving mode. The equipment you suggest seems like a good product but I am actually trying to cut costs with this I was looking into something a little more inexpensive. Tell me what you might think of this utility?

Is this a tower or Imac?
Is there a reason other then curiosity you need to know?

All power supplies have it labeled on them what they are if you need it.

    Not to over simplify things but the power supply AC input is 110 volts if it is a US system. The input supply shouldn't change much from that. I have used a monitor that I will link for you that I use in lab type settings. I use this to monitor the current ups and downs during a day in a lab to see if a 15 or 20 amp circuit will work better. I prefer to use 15 because if there is a spike it is a little safer then a 20 amp on machines. I hope this helps some

    Interesting little product you found there. My only questions would be is this for work or home? If it is for work and multiple devices would doing 1 device at a time be cost effective? For home purposes I can see many benefits of a device like that though. Plus since I need approval to buy new equipment might be a good tool to use to show a savings over time. Sorry thinking out loud there. Either way the tool looks like it could be a low cost solution to your problem.

Power mac g5 shows terrible damage in tower from leaking they swear mom board is fine but its hard to believe. are any of the other parts usable for a g3 to g5 imac or g4 powermac or emac


None of the parts are usable in any other machine.
The coolant from a liquid-cooled G5 PowerMac is toxic. If your G5 is leaking, disconnect the power cord IMMEDIATELY. Flush any skin exposed to the fluid with water for at least 15 minutes.
If you want to glove up and extract your hard drive from the machine so as to save your data, do it carefully. Other than that, my recommendation is to bag up the unit and handle it responsibly as toxic waste, using the same guidelines your area uses for antifreeze.

Imac g4 won't start but shuts down when apple logo appears on screen


Are you sure the iMac is really shutting down or just turning off the backlight? The tell-tale sing would be to let the unit fully boot-up (wait 3 minutes) and the press the button the apple keyboard that ejects the CD-ROM. If the CD-ROM door opens, you iMac is running with disabled or broken backlight.
The inverter circuit on the iMac G4 is known to be weak.
There could be another problem, though. The iMac G4 is also known to have weak internal power supplies. Here's how you can tell:
Hold down the CMD OPT "O" and "F" keys at the same time while pressing the power button. This will tell the iMac that you want to boot into the Open Firmware shell, bypassing the Mac OS X startup. If this works, your power supply is good, the inverter is good and you have a problem with your Open Firmware boot string. To fix the boot string, Power on the unit while holding down the keys CMD-OPT-P-R to zap the parameter RAM (PRAM) and reset everything to defaults.
If you were not able to boot into the Open Firmware shell, your problem is either a failed power supply or a failed screen backlight. The last possible culprit is your iMac could suffer from "Bulging Capacitor Syndrome", where a batch of iMac G4s, iMac G5s another electronics were fitted with a bad batch of capacitors. Eventually, the caps will rupture and cause irreparable damage to the logic board. Only way to verify this is to pull the unit apart and visually inspect. If you see little green or blue cylinders that seem to be bulging or oozing a thick oily goo, that's your problem. Only recourse is to shop around on eBay and look for a replacement logic board.

Imac g4 dead


Hello, The power supply is part of the motherboard in the iMac G4, so it's hard to change it. The repair would certainly cost more than the price of your iMac. You can try to take off the small battery, and reboot it to see if it changes. To open the mac lay it down, screen on the table (on a t-shirt). Unscrew the four screws (they wont come out, so just unscrew them. Pull the screws and take off the silver plate. Then you'll have access to the inside. Good luck

Imac g5 is not turning on. LED1 stays on. I tried resetting the SMU and it didn't work. LED2 flashes on and off making a chirping noise. What could this be


Hello, Sorry to hear you are having troubles,
Is this a 17” iMac G5, if it is, and I think it is, unfortunately, this iMac model was generation 1 of the all in one flat screen design and it's a bit of a Lemon... The hard Drive overheats the video card and the power supply. With time, these 2 elements burn out.
What you have sounds like the power supply. it's a $300 repair, but, it might not be a good investment for you, the new power supply won't last much more than the first one and your video chip won't last much longer....
Best put the money and put it towards a new machine.
Sorry bout that.
