Is there a way to fix a faulty Mac Pro (early 2008)PSU?
I've seen guides for replacing it, but it's an expensive PSU specially if you're not in the US (my case). I've read that most PSU problems are a capacitor or something silly that could be easily replaced without having to spend hundreds of dollars.
Is it possible to repair the PSU I already have? Any ideas?
Thanks everybody for your replies. I do not understand much of PSU, and was wondering if it was a matter of simply replacing specific parts, like the ones that are usually faulty, I thought that kind of knowledge would be good to have documented out there.
But given the fact that it might be extremely dangerous, or excessively complicated, I now understand the reason the information is unavailable, and conform to the fact that I will have to replace it via Apple.
On a tangent matter,the problem seems to me, that this sort of information is really not available even to certain technicians. I took the computer to an Apple Authorized Center and they told to replace the logic board. I still have the same problem and it really seems to be the PSU, but I can't pinpoint the diagnostic.

Renan de Araujo, yes it is possible to repair those. can anybody do that? Yes, with the proper knowledge, tools and practice. You have not yet told us what symptoms your computer has. Also, try to post an image of your PSU with your original question. Follow this guide Adding images to a new question to add the images. If you can, give us the number that is on your PSU, that might help to get some more information.
I have the same problem. My Mac Pro (early 2008) doesn't switch on or, after many tries, it start (fans working) but on monitor I can't see anything.
In really few times it started but once the system start, I can see the grey monitor with apple and then it switch off.
I read that it can really be the PSU unit and, as Renan de Araujo wrote, it cost lot of money to buy new one.
Is the repair possible to be done buy who is not a technician?
Thank you very much.
Same problem here. Mid 2010. I believe it was the PSU Relay switch. Or.. One of the processors is faulty. new PSU is pricey and repairing PSU too risky.
Not much we can do with this $5000 Mac Pro huh? I just wondering.. for the price i've paid for this Mac, did they put cheap components in the PSU? since it's just technically customized ATX model made in China (mine is ACBell Polytech, others made by Delta)
I wouldn't say there's anything cheap in here, quite the contrary: it's overbuilt. But that's not a guarantee against failure. Also, it's not excessively dangerous or complicated to service for adults used to working on electronic equipment. I bought a used Delta PSU for about a hundred bucks and it's back in service. Worth it, since this pricey thing still keeps up with modern Macs.
how do i start the dps-980bba power supply without being connected to the Mac Pro?
