The disassembly and reassembly was of great help, thanks for your time on this.
I'm glad it was of help to you. I will try and create more videos where I disassemble and/or repair, then reassemble various Apple and non-Apple equipment.
Thanks for video mate .Good to hear an Aussie accent :)...Can we buy parts from you ?...I have a 3,1 with faulty PSU. Cheers
Thank you for your kind comment. You can contact us through the About section of our main RUclips page, and we can quote you pricing and availability of any PSU of any Mac Pro.
Hi!, Great video thanks for sharing, I have also the same unit that you've used to test the power supply that you demonstrate, coincidentally I was looking for a video that can help me to repair my mac pro 2009 4, 1 because it did not start when I press the power button. But when I plug it in the outlet there is a blink of small red light near the 220 number, Can I ask for a help how to fix it? and is it mean that my power supply is already busted? should I replace the power supply? Thanks in advance, hope you can help me.
Thank you for your comment. The red light just means that there is a surge of power that goes through to the logic board. It could mean any of the following (and usually in this order): 1) a faulty power supply, or 2) a faulty backplane/logic board, or 3) a faulty CPU board (or a combination of these, but unlikely.) Try disconnecting the power cord for 24hrs. Reconnect and try again. If you don't get power then it would normally be the power supply; or rare occasions it is the CPU board. If it turns on then the backplane/logic board is usually intermittent and will progressively get worse ie: not be able to to turn on at all, or turn on and just the fans spinning.
Hi. Can you advise what is the issue when we hear a buzzing sound from the Mac Pro PSU? Is it failing?
Thank you for your comment. Make sure you can isolate that the buzzing sound is coming from the PSU area. Remove the SuperDrive optical caddy and determine if the fan that sits in front of the PSU is spinning. If the fan is not spinning then you have to replace the whole case as this fan is almost impossible to replace.
WARNING Perform the next step at your own caution. If the fan is spinning, then you can temporarily place a small plastic tool gently inside the fan to stop it from spinning. If the buzzing is still coming from the power supply then there is a component that may be loose and is vibrating, or a component may be failing, so you will have to replace the PSU. Unfortunately, at this stage we do not repair the PSUs but can provide a replacement.
Can I get a cheap or refurbished power supply for my mac pro from 2007? Thank you. This video immensely helped me thoroughly.
Thank you for your comment. The power supply is usually the first component to fail in almost any Mac Pro. Contact us in the About section of RUclips.
@@aa-au Ok will do
How can I know if it’s the power supply that is failing. My computer restarts randomly, i cant see to find the issue. Great video by the way
Thank you for your comment. The computer restarting randomly could mean anything, especially the frequency of restarting. It could mean any of the following (and usually in this order): 1) Faulty or corrupt software - backup your software, format hard drive or SSD and install a fresh MacOS; or 2) a faulty hard drive or SSD - backup your software, install and format a new hard drive or SSD, and install a fresh MacOS; or 3) a faulty backplane/logic board, or 4) a faulty power supply, or 5) a faulty CPU board (or a combination of these, but unlikely.) Try option 1 and/or option 2 and see if this makes a a difference. Options 3/4/5 are more difficult to diagnose and you have to replace expensive hardware.
I have had same issues. Most times fixed it for my by blasting of all dust with compressed air spray bottle and a paint brush to brush it off. Yet since last week's this doesn't seem to work no more. Was hoping perhaps dusting out power supply would help
@@RomboutVersluijsI ended up replacing all parts. Long story short, it was the daughter board. It had some bent pins from removing and installing the ram. Check your pins or replace daughter board.
@@ktangut what do you mean by daughter board?
I know the term donor-board, but not daughter board.
Edit
Googled it, I thought it was one main logicboard.
@@RomboutVersluijsIn the case of the Mac Pro, the daughter board usually means the CPU tray or the large tray that slides in and out at the bottom. This CPU tray contains either 1x CPU, a large heatsink and 4x memory slots (for single processor CPU trays) or 2x CPUs, 2x smaller heatsinks and 8x memory slots (for dual processor CPU trays.) The memory can be populated in any of the slots, but not some of the slots. I will have to release another video regarding memory in these slots.
Hola buenas noches a mi me venden una mac pro del 2009 4 nucleos en 50 dola pero el dueño dice que la pc encendia y a veces no y ya no volvio a encender solo falta disco duro trae 12 gb ram que sera el daño fuente de poder o boton de encendido o la tarjeta madre saludos desde panama
Thank you for your question. When the Mac Pro turns on then switches off, it is most likely going to be the main logic board or backplane board (motherboard.)
I want power supply for my mac pro 2012 mid ... Please help me where i will get new or repair my power supply
Please contact us via the About section of our RUclips page, and we will try and help you the best we can.
So you simply unplug the superdrive? Yours was loose I guess.
Yes, you unplug the SuperDrive. An error on filming, as I had already unplugged it in a previous shot.
@@aa-au thanks. But I got stuck after that. I don't have a small enough tool to use on those torx 10 screws
Or can I buy one from you refurbished? Because they don't sell that anywhere near me.
Yes, we can sell you one. Contact us in the About section of RUclips.
