Xserve G5 Power Supply Recap

[The House of Moth]

Howdy folks,

For those of you still using Xserve G5's, you have likely encountered some bad PSUs. And if you haven't yet, don't worry, you will soon enough! A working PSU will run you several hundreds of dollars on eBay and will likely fail soon as well.
These PSUs need a recap.

Having done 80+ of these Xserve G5 recaps to date, only one was an unsuccessful repair (a massive power surge fried the thing). So for just a few bucks, you can easily bring these PSUs back to life 99% of the time!

I have typed up a few posts about repairing these things:

https://thehouseofmoth.com/recapping-an-xserve-g5-power-supply-part-3-additional-notes/

Now either those posts are really, really poorly written, or people just don't feel like doing this repair themselves. Either way, I have these PSU's shipped my direction from all over the world frequently year-round

If you want one of these PSUs repaired and also prefer to have someone else do it, I'm happy to help!
For the latest info on this, and other, services I offer, take a peek at this webpage.

Long live Xserve!

I am guessing the power supplies are no the same as in the Intel Xserves? Just an idle question because I am too lazy to look it up right now.

You missed a cap, its next to 7. I found this a while back but didn't realize you had this thread. I forget what the value was however.

Depends on the revision of PSU

Oh. Must have missed that. Your sheet definitely helped. How did you get the silicone off without melting the caps? That's the worst

Heh, if you're me, you just kinda pick at it with snips, a flat head screwdriver, and by torquing the caps around a bit, hoping to not mess up any of the other little components around them! I decided to go that route as things are so densely packed up top.

Hey Jeff! We met at vcf Midwest. Yeah, warming up the silicone helps too but too much will ruin the caps. If you don't care about the cap, heat and plyers. I did use snips too. Just did an 8600 Psu...that was just not fun
