Frolyt any good Capacitors for PSU recap?

[gonzo0815]

I got an Enermax EG465p-VE PSU. I bought it as defective for a few bucks, but it works. As this unit is very old, i want to recap it. The caps used on all my Enermax PSU`S are from the shape, size (very thick, mostly 12,5mm) and values in no way ultra low ESR caps. Compared those with the Frolyt EKR, ERY and ERF series of caps i think they are from the same chemistry (e.g no water based elektrolyt). Now i think, that the Rubycon MCZ aren`t the best way to recap an Enermax, as they are only rated for 2000h (i know that they last longer in an PSu, but it is the contribution tho the water in them), the Frolyt are rated for mutch more (5000 -500000h). I don`t know mutch about Frolyt. But in any way i can get them in Germany. What is your opinion on Frolyt? Of course, i would never use them on a mainboard (exept for some very old ones).
The thing is, i can only get some MCZ, and all Frolyt caps, the UCC and Panasonic are way to expensive here (more than 2€/each) for that thing.

The other question is, how long dos i/p caps last? in my Enermax are two 1000uf 200v pc-tur caps. The unit is probably from 2001/2. Should i replace them too?

Input caps last for a very long time.

Well, i agree to that, considering the 1000uf value, should last longer then 5 years, even it is an Pce-tur.

They'll be in series, so your input capacitance is in fact 500uF at 400V, which is pretty substantial.

Interesting that they should be JP-cetur, all the more recent Enermax units use Hitachi HP3 for the initial conversion to DC, and JP-cetur (or -cetul) at the output 'end'.

PS - You mentioned it was defective - what's wrong with it?

This is probably an older desing, it is the traditional desing, without PFC. The new ons are all active PFC, and thus they have only one Hitachi i/p cap with 330uf.
At the moment i don`t know if this psu has any defekt, it was stated that the system had been going down and refused to start up again. I tested it so far only with a old p2 333MHz Board, so i can`t say if it will work wit some serious load. But may bee i will test it soon. I doubt that there are any faulths on this unit, but may be the caps have been reached their end of life.
Inside the PSu i can`t see any defektive. loock all pretty well.
I bought it, to examinate the failure mode of an Enermax psu ;-)
