Blown OCZ Fatal1ty 700w, and almost new CWT? 350W PSU

[Utking]

Hi guys!

First off, I got a problem with a PSU that i got for free, it's an OCZ fatality 700w, what has happened with it, is that the capacitors on the secondary side has blown. (Teapo)
some more info and pictures here:

Now i was thinking of replacing them instead of throwing this PSU away.

the caps i ordered is :
5x Sanyo 16V 1000uF
10x Sanyo WG 6.3V 3300UF

Do you guys think this would work?

Also i have an old 350w PSU. More accurate this one: https://www.badcaps.net/forum/showthread.php?t=24859

And i was wondering if i could use it in my server? maybe replace some caps, (Primary) or is this a bad idea? don't want to toast my hdd's :p

Thanks for all help guys!

The WG is too low ESR, it is intended for motherboard and VGA VRMs. The PSU can start oscillating with them. I have Samxon RS 3300 uF/16 V and Chemi-Con KYA 3300 uF/6,3 V if ya want.

The CWT is waste of time unless you want to learn on it.

Ok, thx Behemot. i've sent you a pm

So i should not get low ESR ones? i thought those were the one i wanted :P Is it any bad if i go any higher on the capacity?

And about the CWT, can i f up my server by using it?

Thx.

Low-ESR, but not ultra-low (motherboard/VGA grade).

If it is stock, it can do all kinds of harm. But you cannot make it THAT much better. Would be safe with recap for some low-power use so if your server draws 100-150 W, than also the efficiency won't be terrible. Still bad, but not terrible.

I took a look on the capacitors you recommended, but the diameter is a little too big, i think my ones are 22 mm, you think it'll work? It would be great to match those primary caps with the same brand for secondary though

And they have a greater capacity than the originals, will this make it better at filtering?

Hmm, I guess i'll toss away the CWT then, do you have any recommendations for a low watt, not too expensive PSU?

Diameter is 10 mm, the other spec is height and usually there is room enough…I checked the photos and the caps also seem to be 30 mm height.

But anyway, can you post pics of yours? It seems to me the one they reviewed at OC3D.net also had some Chemi-Con capacitors on secondary. I am curious if they kept them or swapped all for Teapo and CrapXon in production variant…

Well i took a closer look on this picture :http://www.overclock3d.net/gfx/artic...065955883l.jpg

And all of mine on the secondary side is green, alas Teapo.

The ones on primary side is identical as the ones on the picture. with the same rating too.

Yeah. Those brown there are NCC, possibly KZE series. Seems like OCZ cheaped the production.

Bah, sucky OCZ, anyways the PSU is too good to be thrown away, anyways, thanks for all help

The KZE series is not known to have problems.
