Howdy all,

I hope you don’t consider this too weird a question. Until 2010 I was a PC-only user (10’s of personal PC’s over the years). I frequently got bit in the butt by power supplies that failed after 4 to 5 years and they usually took out something on the motherboard when they died.

In 2010 I finally bought a Mac Pro (see details at left) and am in love. Every PC I had left is powered off & collecting dust. The problem is…I could afford bunches of PC’s, I can’t afford bunches of Macs ☺

My Mac is four years old and just last week one of the OEM HDD’s died. So here’s the odd question: Would it be advisable at some point in time to replace the PSU? How about fans? Anything else I should consider?

I value your knowledge on anything Mac.

Merry Christmas (even for non-celebrants!)

Who is to say that a new one won't fail? I have a mac mini from 2008 and the origional supply is still going strong. I am a PC convert as well. Love them!

Do you run 24/7 or do you, for example, power-off at the end of your day? (as if this may make a difference...who's to say?) :)

I had a used Blue & White G3 which was built in 1999. When I had it, it ran 24/7.
It was still running when I got rid of it this year. They last a while.

Broadly speaking, Macs are designed to last. Not every piece (like the HD for example) is under their control, so sometimes things fail (occasionally even the Apple-designed bits fail, but that's fairly rare).

Having said that, Macs are not designed to last forever, either. It's been my observation that most people who have mechanical issues with Macs do so within the first year, and may continue to have trouble after that. This is why I recommend a full AppleCare warranty, since it covers at least half of the useful life of a typical Mac.

On average, at least in my case, I tend to replace my Mac after 3-5 years (this is probably faster than most people) because as my skills grow I find I need more advanced tools. Typical users tend to hold on to their Macs for 5-6 years, and can reasonably expect in that time to have no mechanical issues.

There's no reason to believe that this particular model is going to have a power supply issue, but at the same time I would ask if you have a UPS on the machine, and if not -- why not?

If the power supply goes…I don't think that it's going to take something else out with it.

If you REALLY want to be prepared…buy the parts…then you have them when you need them. But even this is being "over the top" prepared. Where do you stop with the extra parts:

- extra power supply?
- extra fans?
- extra ram?
- extra hard drives?
- extra optical drive?
- extra video cards?
- extra logic board?

Really…just "go with the flow".:) The power supply could go "pop" tomorrow…or 10 years from now. If you replaced the power supply now…who's to say the current power supply wouldn't have 5+ or more years left in it.

Have you priced a brand new power supply for a Mac Pro (since purchasing a used one would defeat the purpose in this case)?

New power supplies for Mac Pro's aren't $50-$75 like you might find for a Windows desktop tower. Gonna cost you about $300 bucks for a brand new power supply for a 2010 Mac Pro!

As Nick says don't worry about it. If something is going to happen, it will happen. A hard drive failing has nothing to do with Power Supply. Have used DV Warehouse for parts in my mac Pro days.

Thank you for all the input.
a) yes, I always use UPS's (and have a garage full of old UPS batteries :) )
b) $300 for a new PSU isn't unreasonable and far better than having to replace a new MB or something.

I can't argue with this...but I'm not seeing the connection.:Confused:

What does replacing a power supply in a 2010 Mac Pro (before it needs replacing)...have to do with replacing a "new MB or something"??:)

Only a 2010 Mac Pro was mentioned in this thread.

It refers to my original question.
Now I know we're talking Apple hardware here, but this is my FIRST Mac and ALL previous experience has been with tons of PC's. Whenever I've had a PC PSU die, which was frequent, it invariably took out something else too....memory, CPU, or something else on the MBO. :(

I have no previous experience that says "if a mac PSU dies, it's pretty likely everything else will survive." Which is why I'm appreciating the input I receive here!

honestly depends on which mac pro you have you cannot replace the fans with anything new the apple stock fans are basically all you can use.

however depends on 2 things.

1. is this a powerpc or intel mac pro??

2. is it a 1.1 2.1 etc. to find this out go into the apple menu and select about this macintosh then look at the system report it should say

Mac Pro,1.1

or what ever your model is

John: There is no such thing as a PowerPC Mac Pro. All Mac Pro models from the first on have been powered by an Intel processor.

tymixx it is like asking "Do you have a motor car?" Answer "Yes". "Replace the transmission in case it fails"?

When and if will be time enough.

harryb2448,

For arguments sake...
If I was told that the MTBF for my particular car's transmission was "x" years and I couldn't afford to buy a new car...I'd probably replace the transmission before the MTBF was met. After all, who know what else could break if I'm doing 150kph in my Yugo and my transmission goes out! :)

What I seem to be hearing is that I should trust Apple hardware to last longer than off-the-shelf PC parts AND if a PSU unit fails it "probably" won't kill anything else but itself. Yes?

Yes and don't drive at 90 mph. It is not how fast a car can go, what is important is how fast in can STOP!

I have had numerous pc', macs and sparcstations since late 1970's. My dad sold electronics and said the best thing to do with anything electronic is to put it in a closed and leave it on 24/7/365. I have followed his advice and never once had a P/S fail.

I've owned Macs for 20 years.
Two things which have never failed me: power supplies, and SCSI hard drives.
