Hoping someone who recapped these already can give some data on this.
Got a Friend's Enermax Liberty 400 Watt ELT400AWT which has two blown capacitors and is full of CTC & CEC.
Blown capacitors are:
C17 - 2200uF 16v on 12v Rail
C14 - 1000uF 10v on 5vSB.
The rest test OK but the 3300uF parts aren't as close to their rated value than the other ones are... Anyway, I decided to replace the lot, since they're a bit lame and I already pulled them all for testing anyway, and the PSU is some several years old.
I found that I should be able to cram 12.5mm diameter parts in for C18 and C19 (a little up off the board), as long as I drop C21 down to 6.3v to get a 10mm diameter, then I don't need to try to find any 3300uF in 10mm diameter.
My current selection is thus:
These should all be suitable, right? I picked whichever had the highest RCR (overkill?) and ESR that was as close as possible to what I measured on the old ones.
Unless anyone has used these already and knows otherwise, I'll get them.
Can't compare anything with CEC\CTC datasheets as they don't seem to exist. Nobody seems to have heard of LFFM or LFKM. There was some reference to KM series that seemed to come from Rifeking (Who seemed to be associated with CTC) but those are GP and have low RCR which doesn't make sense.
Only some CEC PCE-TUx datasheets exist which don't help since they are just the small (<22uF) GP capacitors that I'll be replacing with FC or PW.

Half of the computer problems is caused by bad contacts 
And don't you recap PSUs all the time sou it would only make sense to buy some on stock?
(and yes, I waited for them to cool down after desoldering).
