Hello.
I've got this killer monster dual-Xeon Mac Pro which is the best computer that I've used so far and.....
I'd like it to last.
I was a little suspect of the PSU in particular because of my G5 iMac PSU with the bloated Ltecs in it.
So, while I had the system apart for dusting I thought that maybe taking a close look at the PSU might be a good idea.... so today I disassembled , cleaned and inspected the PSU and even took some pictures.
The PSU is made by Delta and is rated at 980w output. It appears to have six 12V outputs of 11-18A each and one 5v standby rated at 5A. There do not appear to be any 3.3V or 5V outputs. The PSU has a total of four similar output connectors with 8-12 wires in each (keyed to prevent mis-connects). There is no internal fan, but there is a 120mm dedicated PSU fan mounted in the case.
Here's the Capacitor list, with the exception of one tiny NCC that was under a heatsink and gobbed down with glue and of course the ceramic disc and "other" caps:
3x NCC 270uf/450v KMD series
16x ??? 330 /16v Polymer caps marked "PS665"
6x Nichicon 2200uf/16v PW series
1x NCC 2200uf/10v KZH series
1x Nichicon 100uf/25v BT(M) series
2x TAICON 2200uf/10v PW series
2x TAICON 220uf/25v PW series
1x TAICON 220uf/50v PW series
1x TAICON 100uf/50v PW series
All caps appear to be standard sizes and in good condition. The PSU seems well constructed and when running the system is a paragon of Stability. And Silence. Speed too.
I was thinking that maybe it might possibly be a good idea to replace all of those TAICON caps even though they look OK. Or maybe just get all of the caps under 450v just to have on hand.
Does anyone have any idea who made those polymer caps?
Anyways, I've noticed a lack of information available on Mac internals, especially the Mac Pro. So this thread is about what the PSU looks like and a little bit about it. By the way, the motherboard appears to be Foxconn made and has a whole bunch of NCC on it.
Have Fun,
Keri
