Hi All,
Long time occasional reader - first time poster here.
Need help from community to revive (recap) Dell Z930P-00 Power Supply.
/Prehistory.
Dell Server was shut down about three month ago and according to reports, both Power Supplies were (presumably) fine.
Attempt to restart Server about two days ago was unsuccessful: one Power Supply had no lights (Line, Trouble, Active) at all and the other had only Line light flickering repeatedly.
Disassembly of both Power Supplies showed heavy dust buildup, which was removed with long bristle brush and compressed air.
After cleanup, one Power supply still dead (no any lights or relay sounds) and the other has steady Line light, steady Trouble light and little relay engages.
Close inspection revealed aging/bulging capacitors at the output stage in both units./
As original caps are obsolete and no longer available, day worth of on-line searching for suitable replacements lead to nowhere...
So, asking help from community for advice of close equivalents to the following caps below.
Ideally, from Digi-Key or Mouser stock.
Each Power Supply has:
Rubycon MBZ 105° 1800uf/16V - 3ea. - 10mm/23mm - need new ones.
Rubycon YXG 105° 100uf/25V - 2ea. - 6.3mm/11mm - not sure, most likely OK.
UCC KZG 105° 2200uf/10V - 3ea. - 10mm/25mm - bulging tops, definitely need new ones.
UCC KMQ 105° 330uf/450V - 1ea. - 25mm/52mm - most likely OK.
UCC KMQ 105° 270uf/450v - 1ea. - 25mm/42mm - most likely OK.
Am I on the right track to replace only 1800uf/16V and 2200uf/10V caps to start with?
Please see attached and advise.
Thank you!
