Re: Power supply build quality pictorial. part 2
A friend brought me this Lucent PSU out of an SGI Octane (if i've understood correctly), after reported random freezes & crashes. All Japanese caps, none bloated, which turned my suspicions towards the mainboard and local VRM's.
Now, i know almost everyone's heard the phrase "built like a tank", but DAYUM!
3-board construction:
- bottom-most board (4th photo) seems to be one the secondaries (or possibly some DC/DC business going on), chock-full off fat Nichicon PL's
- middle board (5th & 6th) is the mains-input and active PFC, by the looks of things, plus possibly some stand-by rails(?)
- top board (7th, 8th & 9th) is yet another set of outputs, but this time complete with part of the primary (hence the 450v caps and transformers)
