200W-250W seems about right for those heatsinks. Boschert Inc., now part of Artesyn, used Elna for O/P caps in the late 70s. The Elna moved their factory to Korea (IIRC), lost their "formula", refused to acknowledge it, and Boschert was forced to do a lot of warranty repairs and "eat" a lot of caps they had in stock. I was informed of that in 1980 by Boschert's component engineer when I worked there. Hopefully Elna has learned much in the past 25 years.

Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

It's not crap, merely over-rated. It should be good for 200-250W - the secondary-side caps seem to be Elna/Chemicon, so it should be OK. Just pre-emptively replace the auxiliary primary-side flyback capacitor (visible to the right of the top-most transformer on the 2nd pic) with a long-life Nichicon PW(M) or Chemicon LXA and you should be OK for many years of safe use.
i have seen noname caps with the same vent elna uses.
a pic of the caps would be nice.
whew i found a fujiyuu. happy happy. good luck monika
You've found one Fuhjyyu cap in that ISO power supply, my Antec PSU is loaded with them!
I'd say that ISO PSU would be good enough for a Celeron 2.6GHz Prescott machine.

i have Fuhjyyu in several units. the most important thing is whether the psu design is ok so it wont nuke the computer when they fail.
In this case it was quite suprising to find one Fuhjyyu amongst all those Koshin when i was checking the photos.
At work one time an Antec TrueControl 550 (pretty expensive at the time) blew up and also nuked the PC. Somehow the protection didn't work. An autopsy was done on it and all the capacitors and all the transformers in that thing went bad.
The horrible odor was not good and the thing was way beyond repair level so it was trashed with the system it nuked. Too bad I have no pics.

If the O/P transformer had a primary-secondary breakdown, the current limit and OVP circuits aren't going to help. I'll bet the ashes didn't smell too good.

sounds like what happened while i demonstrated the lack of overcurrent protection in a powmax built black knight unit.
when it failed internally it blew flames and sparks out the vents for a good 5 minutes before it blew a fuse.it continues to burn for quite a while afterwards and the fire traveled down the harness dripping flaming plastic.
the best reason to avoid cheap psu.

You're right, the ashes didn't smell good. The capacitors had a scent of ammonia and rotten fish mixed together!

That Antec had sparks going everywhere on the inside of it and it caught fire, but it was very small and was extinguished. The only thing that survived in that thing were the two fans (it was a dual fan PSU) and I have them in my closet. One 80MM and one 92MM.
I now got an Antec SmartPower SL450 450W P4 and SATA ready PSU, hope it doesn't have a painful and smelly death like the Antec TrueControl 550 at the place I work at.
