    Default OCZ StealthXstream 600 troubleshooting

    I've had this power supply for about 3 years now. Recently the computer started shutting down during sessions of Call of Duty Black Ops after no more than 15 minutes of game play. Initially the computer just shut off and automatically restarted 5 times in a row. Then it would stay off and not respond to pressing the power button after about 2-5 minutes of off time. Did that another 5 or so times and then no response at all.

    Decided to replace the power supply and the system is running properly again. Took the old PSU apart checked the fuse, and the only visual signs of issue seem to be these two capacitors in the pictures I have included. The tall cap on the edge of the board definitely traces to the 3.3 volt sense wire...and the other is located towards the center of the board in between two 12V transistors.

    Would someone with some repair knowledge tell me the likely hood that my problem is just these caps based on the symptoms?

    Yeah, it's bulging and on its way out. You definitely shouldn't use that PSU any longer.

    I think he was looking for specific diagnostic help. He's already replaced the unit in service.

    I'm sorry, Legend, I'm useless without a circuit diagram. Perhaps some of the experts here can help.

    You can replace those caps....but the question then is, when are the other ones going to fail? You'll end up chasing bad caps after bad caps.....and how much is your time worth?

    That power supply isn't worth fixing given its performance it had when new.....now, years of use later and every cap is probably at the edge of failure, the rest of the parts weren't good to begin with.

    Junk it.

    look for all capxon 2200/6.3v. the two of them already bulged on your picture. maybe this unit have 3 or 4 this c(r)aps on its secondary. AND a small capacitor (100uF, 25v, capxon KF) labelled C41 near the switching mosfet.
    replace them. these caps are the most commonly fail on OCZ stealthxtream.

    i usually use panasonic FC / Nichicon PL /PW 2200/6.3v (they have slight bigger diameter) and NCC KY 100uF/25v

    maybe you want to check the capacitor at -(minus) 12v rail

    other caps like teapo 1000/16v ost 2200/16v rarely fail.

    Just replace every aluminum electrolytic except the bulk cap. It's possible for them to die without visible signs of failure, and the cost of shipping makes the shotgun approach much cheaper if you don't have an inventory of this stuff sitting around.

    All you really need is a usable 40~60W iron (not necessarily grounded) and some braid. Besides that, you can follow the instructions for recapping motherboards on the badcaps.net main page verbatim. It's not rocket science, but it takes patience.

    Sorry to bump such an old post, but I just got done repairing mine and it was the C41 capxon 100uF/25v. It was showing a little bulge out the bottom, and only measured at 44uF. My 12&5v were jumpy at about half voltage, but all other voltages were fine. Now with a new C41 it's all solid. The other capxon caps tested good and were were not bulged or leaking yet.

    I disagree with you. Only about 1/3 of the caps are capxon. It's totally worth reparing. It's a nice PSU. Not saying it's the best thing out there, but for sure worth a few new caps.
    These guy's seem to like it, they tested it at over 700watts.

    It's totally worth reparing.
    to each their own. For my time and money, there are a shed load of very high quality gold and PLAT rated units that will out perform it in every respect at significant levels....

    A $300 unit that can still run your quad-SLI platform...then yeah, some repair work is in order.

    Something that can be replaced for $60 with something twice as good and a new 5 year warranty.....not so much.

    Well, $80 if you really need the wattage.

    http://www.newegg.com/Product/Produc...82E16817182262

    However, I seldom see people with 600 watts that really need more than the 450 watts..


    From your link. Efficiency 80 to 83% when new. regulation 3%
    VS. new at 88-92% ...The power savings over the next 5 years pays for it not even counting the aggravation and risk to your other investments (CPU, GPU, MB, etc. etc.)

    False economy....good skill to have in case of the zombie apocalypse...but not a great use of your time otherwise. JMHO...
