OCZ-520 Looks Good, but Won't Work

Re: OCZ-520 Looks Good, but Won't Work

you know the routine. replace every electrolytic in there. then fix the other problems. you can tell OCZ you're a repair tech and maybe they'll send you schematic. more than likely they won't but it's worth a try

Re: OCZ-520 Looks Good, but Won't Work

Hi,
I am the other guy with the OCZ 420, in my case the PSU was ”working” the syptems was that when u power on the comp it was on but not fully on so u will need to shut off and on repidly untill it will b fully on, so i opened the PSU and like 7 big caps was dead so i recap all the big caps on the side where all the cable that goese to the PC n the ones under the heatsinks lond story short just recap the big ones n even the little ones.

Re: OCZ-520 Looks Good, but Won't Work

so it is.
the transformers kinda tricked me.
iirc ocz is dead now.better luck looking for topower schematics.
and the few i have seen had all asia x /asiacon caps that were nfg from new.

This is a Topower platform from 2004. I have one maxed out with APFC. I remember mine had all caps except primaries blown. Even some of the small ones were dried or blown. On the fan controler too...

Re: OCZ-520 Looks Good, but Won't Work

to cut the thread short, just fill it with panasonic FR, FK and FC.
EVERY CAP OTHER THAN THE MAINS FILTER.

Re: OCZ-520 Looks Good, but Won't Work

Why only panasonic all the time? I have better equivalents, Samxon RS and NCC KYA, 3300 uF D10.

Re: OCZ-520 Looks Good, but Won't Work

panasonic are pretty cheap at farnel - that's why

Re: OCZ-520 Looks Good, but Won't Work

All caps are pretty cheap at mines.

And they have 3300/16 D10 yeah? Show me.

Unless I actually need 3300uF 16V in 10mm, I always opt for Panny FK, even though they are a bit more expensive. Samxon RS may not be too bad, but they are not Japanese, and Panny are.

Re: OCZ-520 Looks Good, but Won't Work

So you are saying ROE, Cornell Dubilier etc. are not good because not japanese. Oh yeah…hard logic

First Samxon RS are in use since 2006, that's 8 years and nobody ever seen a bad one. I would say it is already long proven they are much more than "not too bad". Mine in Enermax Liberty 400W have more than 20000 hours on them with temperatures around 50 °C and 200-300 watt load for a long time.

i'm not sure many pana's are actually made in japan anymore.

anyway, i'd prefer not to have things from japan that may be contaminated wih radioactive elements.
maybe the yaesu battery fires in the dreamliner were down to contaminated manufacturing!
i would have liked to have seen some research into this, but it never happened.

yep, just checked.
FR series pana's are made in Malasia.
FK and FM datasheets dont say country of origin.

I hope they still get their materials from Japan, though, even if they're assembled in Malaysia? I just hope that "made in Malaysia" doesn't mean that Malaysian-made Panasonic capacitors are just as shoddy in quality as the "bad" Malaysian brands (IE Wincap).

Re: OCZ-520 Looks Good, but Won't Work

well the FR series caps have not failed on me yet.

Re: OCZ-520 Looks Good, but Won't Work

Country of origin is not the point IMO, you can make good cap anywhere.

Man Yue has been possibly sourcing electrolyte from Nichicon for their top GA/GC ultra-low ESR caps, they were only making their foils and assembling it. Who knows what else even today they buy from other manufacturers. And their other caps besides GK, GF series are top, with X-CON polymers being one of the most used polymers at all.

So as for Samxon RS, I say they are comparable with japanese caps unless proven otherwise, that is sure to me after all the time they are in use. Only drawback is that as long as it is somewhat older series, the ESR and lifetime is not comparable to new series in other, more common package sizes. That's why I have Chemi-Con KZN 3300/16 D10x40 mm being produced…
