    OCZ Failed Capxon Caps

    Hey all,

    I have an OCZ Powerstream 600W (OCZGSX600) that has been faithful to me for many years but recently has failed. I cracked it open to find it full of Capxon caps with one noticeably bulged leaking top. I ran to Radioshack () to grab a similar cap and swapped it out with no help, then discovered another nicely hidden cap that has also blown. I've decided to recap the whole PSU with some quality caps

    Here is an inventory of what's on the PSU

    Capxon Caps
    (1) 420uF 420V LP 85C
    (2) 2200uF 6.3v KF 105C (Labeled C710)
    (5) 1000uF 16v A3C1 105C
    (1) 47uF 25v

    One oddball OST Capacitor
    (1) 2200uF 16v

    I can't seem to find many 420uF caps so I'm going to swap it for a 470uF 105C similarly sized. My big question is could someone recommend me a quality brand/series to replace these with?

      Re: OCZ Failed Capxon Caps

      OCZGSX600 tells me that's a GameXStream power supply, not a powerstream.

      There's no CapXon LP series rated for 420uF and 420v - in fact 420uF is not a standard value, so you'll have a hard time finding any such capacitor. You probably mean 470uF. Either way, for that primary capacitor, the capacity can vary a bit, it's not critical.

      470uF / 420v is 40mm in diameter, 52 mm in height, the ripple is 3.9 A (but this value is basically Capxon bullshit).

      2200uF 6.3 v have 1470mA ripple and 0.095 impedance.
      1000uF 16v have about 1350mA ripple and 0.06 ohm impedance. (if they're also KF series)

      You need to pick capacitors that have equal or higher ripple, along with equal or slightly lower (but not by much) impedance. Last, make sure they fit: the capacitors seem to be all 10mm in diameter but who knows, some may be 8mm and 10mm ones won't fit.

      470uF 420v replacement:

          If I may add you can find all of these value caps on Mouser.com as well, they don't have any min purchase. Also, you can get Panasonic caps, which in my opinion are the best ones you can get and they are the only ones I use when I replace a cap. You will find all of these in Panasonic's FM Series and FC Series Caps.

              Thanks for the reply! You are right about the GameXStream, it's been a while since I've tinkered with my PC

              The bizarre thing is that the cap is indeed a 420uf 420V (or at least labeled so), I have it right here in my hand. I couldn't even find that value in the Capxon LP series datasheets and that's what made me end up posting here haha. It's measured case size is 30mm wide and 47mm long

              I'll pull the rest of the caps and ensure their specs match before ordering, thanks much!

                  Re: OCZ Failed Capxon Caps

                  I may have an old datasheet then. Weird.

                  Then my recommendations for the large capacitor won't be good, as the smallest I linked to is 35 mm in diameter.
                  Go through the capacitors section there, filter by voltage, capacitance and diameters that would work on your power supply, then sort by ripple so that the highest value is at the top.
                  Then go through them and pick one that's in stock and has a convenient price and a reasonable ripple value ( I would say 2A or better)

                  As for the others, I don't contradict Peter, there are much better capacitors than the ones I recommended, but those series I picked capacitors from are closer to the specifications of the old capacitors.

                  The old capacitors have kind of a high ESR/impedance for a power supply at 0.06-0.09 ohm, so it may not be impossible that the power supply relies on this impedance to stabilize the output. Going with too good capacitors with much lower impedance may cause issues with the power supply.

                  The series I chose from are if I remember correctly Panasonic FC, FM, FR united Chemi Con lxz, kze, ky , Nichicon he, pw

                      The plot thickens...

                      the 1000uF are 105C SY series, however the SY series datasheet I found only says the series is from 1-330uF... wtf?

                          They can't be SY because SY is a miniature series, only 7 mm in diameter. I doubt yours are of such small diameter.

                          FSP (the company that made the psu for ocz) isn't usually that stupid.

                              Turns out they were TEAPO SY series caps haha

                              I've found good replacements for all of the caps now. They're all panasonic FR series except the oddball sized 2200uF 8x25mm, the only one I could find with this size was Nichicon HM series at 8x20mm

                              The LP spec sheet for the 470uF doesn't give impedance numbers, neither does the replacement I found

                                              Hello,

                                              First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                              I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                              I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

                                              Hello!

                                              I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                              The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                              I have studied the board and...

One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.

                                              Good evening

                                              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                                              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                                              But I was also suprised about the bigger boys, which are 330µF 25V.
                                              Could it be they used 25V caps because they were cheaper / available at that time?...
