#Mac pro power supply removal mac

I ordered some replacement caps for these TAICON caps and am waiting for the parts to come. I'm just wonder if any one had replaced TAICON caps and this replacement cured the problem. I guess the failure rate of this power supply is so high that even if I'm lucky I wouldn't be able to find a PSU which will last next a few years. All sellers just turned on the computer to see if it boots and the dismantle to sell. After three purchases, I gave up finding a used one. So, I tried to purchase used ones from E-bay. After checking multiple possible causes, I came to the conclusion that the PSU is problematic. As soon as, 250 W is reached, the computer shuts down. I used a Kill-A-Watt to see the instantaneous power. Basically, with any App that requires some power the computer shuts down and reboot. The computer boots but immediately shuts down and reboot when I open Safari (or Firefox). By the way, the motherboard appears to be Foxconn made and has a whole bunch of NCC on it. So this thread is about what the PSU looks like and a little bit about it.

Or maybe just get all of the caps under 450v just to have on hand.Дoes anyone have any idea who made those polymer caps?ДЄnyways, I've noticed a lack of information available on Mac internals, especially the Mac Pro. I was thinking that maybe it might possibly be a good idea to replace all of those TAICON caps even though they look OK. The PSU seems well constructed and when running the system is a paragon of Stability. 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:ДЎ6x ? 330 /16v Polymer caps marked 'PS665'ДЄll caps appear to be standard sizes and in good condition. There is no internal fan, but there is a 120mm dedicated PSU fan mounted in the case. The PSU has a total of four similar output connectors with 8-12 wires in each (keyed to prevent mis-connects). There do not appear to be any 3.3V or 5V outputs. It appears to have six 12V outputs of 11-18A each and one 5v standby rated at 5A. The PSU is made by Delta and is rated at 980w output. so today I disassembled, cleaned and inspected the PSU and even took some pictures. 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.

I was a little suspect of the PSU in particular because of my G5 iMac PSU with the bloated Ltecs in it. I've got this killer monster dual-Xeon Mac Pro which is the best computer that I've used so far and.
