Conclusion
-------------
Was it important to recap this otherwise a still good-working psu?
It is very subjective (to me). This recapping was done when i was learning the PSU recapping in my beginning time. I blindly recapped all the caps to the smallest ones.
But this is my conclusion now:- the big primary caps (teapo lxk 680uF 200V) don't need to be replaced. the only reason they should be replaced will be for upgrading the capacitance. (i forgot to use my 820uF chemicon KMH though, the 680uf ones is used instead.)
- no caps were bulging, but there's nothing wrong with recapping the Jamicon TM and Teapo SEK caps (output filter), if it's not japanesse caps i can't be sure it will last long. 2-3 years are probably okay with taiwan/chinese caps but not 5 years.
- original fan was replaced with Adda brand (brushless). should be using the ball bearing ones (i forgot )
- all tinny caps was replaced. i want to be sure that the lytics wont be the first to fail in this psu. can't be 100% sure though.
- it don't even cost me $8 for replacement parts. it's a mere hobby project, desired to gain some skills and knowledge in recapping. thank good this psu wasn't filled with fuhjyyu caps like the others fortron 300W.
- powering an prescott 2.8ghz system (been 4-5 month) is okay (only 11A on 12v? ). don't underestimate a good 300W psu!

Mmmmm ... heavy metal ... UCC KMH and LXZ - good taste in caps.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Well, those are abundantly available. With too much good caps in your hands you'll want to recap just everything.

i don't think the jamicon tk is a good capacitor. i found this on our badcaps forum:
AOpen FSP300-60BT(12V)

pretty much the same psu:

Per Hansson's Nexus NX-3000 300W
Well yesterday I took it apart, the problems lies with 4 bulging Fuhjyyu TNR 105°C caps 2x 3300uF 10v and 2x 1000Uf 10v
