micro ATX PSU recapping help needed

[smile]

Hello, I have this m ATX PSU, in my old via-epia MIII 10000 PC.
The PSU is dead 3rd time.

So I decided to replace all caps !

Here is how the PCB looks like, The caps are:

1. 1x SACON 1000uF 10v 8x15mm
2. 5x Jamicon 1000uF 10v 8x20mm
3. 1x STONE 470uF 16V 8x11mm
5. 2x SACON 1000uF 16V 10x17mm
6. 4x STONE 470uF 35V 10x15mm
7. STONE 47uF 16v 6.5x8mm
8. STONE 10uF 25v 4x8mm
9. STONE 100uF 16v 6.5x8mm

Looking forward what to use to replace them.
The 1000uf I think I should replace them with Rubycon ZLJ 1000uF 16v
The 4x STONE 470uF 35V 10x15mm with Rubycon ZLH 470uF 35v

Re: micro ATX PSU recapping help needed

Can I replace the 1 and 4 with SANYO 1800uF 16V caps, to get it running while I wait to get the proper caps?
Seems I have some SANWA 1000uF 16V caps too, what should I use?

Might be just the camera, but the caps numbered 4 (C53 and C55) look bad. Replace them.

The Sacon must go, I don't trust that brand at all.

I suppose you could use Rubycon ZLJ, but they're a bit very low esr and those Sacon I don't think they are.
I suppose you could use Samwha, but those aren't that great.

I'd recommend going for some series of capacitors that are not only low esr but also with a higher temperature rating, such as Panasonic FM or Panasonic FR or United Chemicon KZE or KY

See if it the shipping is cheap enough to be worth getting from Farnell:

I buy from them all the time and shipping to here in Romania is about 4$ for any size package and at least you know the capacitors are new and original, not fakes.

Thank you for reply, is using low ESR caps bad if they don't need to be low ESR?

I buy from them all the time and shipping to here in Romania is about 4$ for any size package and at least you know the capacitors are new and original, not fakes.

For my country that is specified as 18 LTL or 7.5$

I can get free shipping on caps and everything from rsdelivers.com but they sell 5 pieces as minimum on some caps, so it is not always the best source.

I can get for example Nichicon UHM1C102MPD6 for 0.41Eur locally are they any good?

Re: micro ATX PSU recapping help needed

You need low esr capacitors on that power supply, the majority of capacitors on a switching power supply are low esr.

Nichicon HM is good, IF it's not a fake.

rsdelivers is good store.

If you're interested, I could mail you some capacitors at the farnell price + about 2$ for the envelope and stamps, I have some in my personal stock, i usually buy in volume what i need so i have a lot of panasonic fm/fr and nichicon hm/hn here.
