Recapping of Corsair VS450

Re: Recapping of Corsair VS450

Sorry I forgot attaching the pics of the PSU.

It's important to get the ESR value right...

The trouble is that most of the specifications omits just the ESR.
Anyway the CapXon series is GF except for the 12 rail, which is KF.
Yes, I am aware that good caps are rather expensive, but Momaka encouraged me to repair this PSU.
As regards the motivation of recapping, I explained it in another thread about Technoware recapping.

Re: Recapping of Corsair VS450

Pls take a look at the series used...

A 'CapXon' cap can be anything from a 'GP' KM series, to a high end FH series...
Same with the other caps...

It's important to get the ESR value right...

Besides:
Do you want to do it because of fun and learning or do you want to 'improve' the PSU?
If you don't want to do it just for fun, it may be better to buy a new, better PSU because it's cheaper...

Because those caps aren't that cheap. You can expect about 10€ for all of them, besides the primary one...
That one alone costs about 2,5€/piece...

Besides: 180uF/400V caps are something found in rather small PSUs in the 300W range...

Hi,
for a year I have got a still working Corsair VS450 PSU. While searching in this section I have found some traces of this topic in several threads but no specific one. Encouraged by your comments and my curiosity I opened it (so forgetting about its warranty) and discovered that it has been capped by poor quality only capacitors, which of course I would recap.
While I am not 100% confident of the respective rails (sorry I am still an amateur novice), here is the whle list of the capping:

Filter: 1x Aishi 180uF, 400V
Primary: 2x JunFu 2x 220uF, 25V + 2x JunFu 2x 4.7uF, 50V
Secondary:
5VSB Rail: 1x Capxon 2200uF, 10V + 1x Aishi 1000uF, 16V
3.3V Rail: 1x Capxon 2200uF, 10V + 1x Capxon 2200uF, 6.3V
5V Rail: 2x Aishi 1000uF, 16V
12V Rail: 2x Capxon 2200uF, 16V
-12V Rail: 1x Capxon 2200uF, 16V
Others (PWM, fan etc): 2x JunFu 2x 2.2uF, 50V + 1x Aishi 1000uF, 16 + 2x Capxon 100uF, 16V

My purpose is to replace every cap with the IDENTICAL ones but of good quality (and low ESR in the secondary zone), any suggestion?
Moreover, some questions arise:
1. is the capacitance of the filter big cap high enough (180uF), or should I consider (if it is possible) to increase it?
2. how is it possible to put together caps of different voltages besides different capacitances as I saw in some rails of this PSU?
