Good nichicon series?

[Oerg866]

I have a few leftover nichicon HD(M) and my 2x ASTEC ATX202-4515 200W PSUs have nichicon PM(M)/LK(M) caps in it as well. They are all not showing visible failures and work great in both cases (the PSUs drove an emergency setup of a Pentium 4 + Radeon 9800 once) and the HD(M) were on an ASUS board that ran at 140FSB (and died due to BIOS update fail).

The PSUs, as I said, work great still after 11 years of usage.

1. Are the nichicon series i listed in this post good or should I replace them instantly?

2. what other nichicon series are good?

Basically all nichicon series except HM(M) and HN(M) are good.

Even so, only older HM(M) and HN(M) are bad (I think about 2004 and down should be watched out for.)

Yup, Nichicon HN & HM from 2001-2004 had a manufacturing defect.
Other than that you only have to worry about age and heat like any other cap.

The (M) is just the uF tolerance +/-20%.
It's not part of the series name.

'right, thanks for the answers

@PCBONEZ: Should I recap the old 1997 PSU (heh, case has a 1999 datecode, the board says 1997) soon because of the age?

That's a judgement call.
ASTEC units are usually very high quality.
If it's still working properly I wouldn't worry about it to much unless your business depends on it or something like that.

Oh? That's not bad considering that I got these two in two computers I got for free from my local church (yes, that's right )
