a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

[kc8adu]

in the last 3 weeks i have gotten 14 350w fortron,fsp,sparkle,ect units in as dead.
each has the fujjyuu caps leaking.
the teapo's look and test fine but i change them for pm.
i have seen a few in the past but now we are seeing lots of these here and at the shop.
at least these are worth recapping!

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

glad my 1 Sparkle 250W (2001) has good Fuhjyyu's. 2 PowerMan (Fortron OEM) PSUs (both 250w) in comps I am responsible for (2002) also have good Fuhjyyus.

jeez, they are not fortron bluestorm 350w are they?

forton is oem for OCZ!

here we got

fortron 350w - 38 euro
fortron 350w bluestorm - 55 euro
fortron 400w bluestorm - 76 euro

i have Fuhjyyu in a few but i am yet to come accross these uber shite versions like in the antecs previously posted.

my guess is these caps are coming to the end of their (short) lifespan.
i see lots of bad fujjyu caps in other devices so i doubt there is such a thing as a good one.

Channel-Well CWT-150 FATX from a Shuttle SV24 SFF - loaded with Fuhjyyus. This is a 1U/FlexATX sized unit, so everything is crammed tightly inside the case - there are a bunch of caps located beneath inverted L-shaped heatsinks on the rectifiers, making replacement difficult. Most of the secondary-side caps are 10 or 8 mm dia, limiting the capacitor choices.

I used:

2 x Panasonic FC 1000/10 on the +5v rail
1 x Panasonic FK 1500/6.3 on the +3.3v rail
1 x Panasonic FC 1000/10 on the -5v rail

Left unchanged: Several 470uF Fuhjyyus. One 1650uF/16v Fuhjyyu in 10mm diameter on the +12v rail - replacements in good brands in that size are pure unobtainium. Anyway, the 12v rail is not heavily loaded on the Socket-370 SV24 system - there's only a single DVD drive and hard drive installed.

Burn-in testing after recapping shows the +5v rail rock steady at 5.02 and the +12v at 12.12 with minimal drift. I'll take my chances - none of the remaining Fuhjyyus shows any signs of trouble yet.

Just for reference - what are the replacement choices available for 1500/16 or 2200/16 in 10mm dia.?

I hate those things - my 420W has three of those needing replacement, and only 10mm will do. I emailed CWT's US branch and they told me I could use higher value caps, but I've been too scared to try it. So, that PSU is now in very limited use powering hardware I don't care about anymore with a somewhat high 5v rail.

There are Panasonic FC 1500uf 16V caps at Digikey in 10MM diameter.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

Thanks, the Panasonic FC 1500/16 10x30 seems to be a good substitute - still need to check the clearance to the heatsink above it - may be a close fit.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

That was a mistake, that was P10254-ND (12.5MM) and it was supposed to be P10255-ND (10MM).

the 470 ones are likely on -12 or +5 stby.change them now as they go bad too.
had a system in here that took a 10 min.warmup to repond to power button.+5 stby was 8.3v with 4v p-p trash! lucky it didnt kill the board.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

We gotta now the size (diameter, etc.) of the 470uf caps too. I find it to be easier to find replacements with this little imformation.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

I just pulled apart a CWT ATX-375 - the Fuhjyyu 470's in there (all 3 of them) are 8mm diameter. Didn't pay close attention to the length - this one has plenty of room.

Two need replacing in this unit - it's a friend's PSU, so I'm recapping everything and making a gift out of it.

Digikey also has nichicon 1500uf HE 16v 10mm. P/N 493-1529-ND

I had the same 1650uf caps and was lucky enough to wrestle in a panasonic 1800uf 25v FM 12.5mm cap. P/N for that is P12381-ND.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

There are at least three Fuhjyyu (M) P7 470/10 8x13.5 - one each on +5v, +5vsb and -5v. I've now replaced them all with Panasonic 1000/10. There's also a Fuhjyyu (M) P10 470/16 8x14 on -12v, where I was able to squeeze in a Chemi-con 470/25.

The Fuhjyyu 470/10 and 470/16 are almost identical in size and appearance. There's also a Fuhjyyu (M) P10 1000/10 (blue sleeve) in size 10x20, as well as a Fuhjyyu (M) P7 1000/10 (black sleeve) in size 8x16. Go figure - I can't think of better reasons to avoid Fuhjyyu.

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

i ordered some 470@25 panasonic fc for a cnc job and found them also good for these 470@16 fuhjjyu.
8x20mm iirc.

Here's a replacement for that, 8MM diameter too.

Cool

I'm about to post pics of my CWT 420W in the pictoral thread - this one's going to be a nightmare to recap. It now has 4 bad Fuhjyyus - two 1650@16v, 10x25mm; one 1000@10v 8x20mm; and one 3300@10v 13x22mm. Most of these have no height restriction, but one of the 1650's must be less than about 28mm tall. There are also two Capxon 3900@10v 13x22mm I plan to replace as well, though they look ok.

To make things infinitely worse, there's a vertical PCB glued and soldered in there that will need to be removed to gain access to some of the caps. And the PCB is dual layer. Fun times ahead

Re: a sudden rash of fsp,fortron,sparkle,ect psu's with dead fujjyuu(sp)? caps

A good replacement for the 3300/10v Fuhjyyus/Capxon is the Nichicon PW(M) 3300/10 12.5x31, if you have the space. They're rated for 105c/7000 hours endurance, 0.025 ohm ESR at 20c, and 2.3A ripple current. My favorite caps for the +5v rail anywhere - PSUs, motherboards, etc.
