    Along with GC, the GD are not part of a standard portfolio of Samxon, and were made especially for use in SMPS designs... They're a special-order product.

    Yeah, and HALF the estimated (yes, I know, estimated) life span.

    But as McSteel said, GD is a special order, so probably didn't had much testing, maybe SamXon only tested it till 2000, but isn't 4000 a problem.

    Something else is also good by me. But because it is a CWT, SamXon looks to be the best option.

    Still the next CX(M) needs to be better for todays price. Independent voltages regulation and some better caps, should be doable.

    Well... main purpose being putting DC to DC in it. I told the engineers about GD and they're looking into it. *shrug*

    I was under the impression that GD was an ultra-low ESR series like Nichicon HM or Rubycon MBZ. They are generally considered too low ESR for an average PC PSU - possibly enough to upset the feedback loop and make the ripple worse in some designs. As for reliability, it's hard to say. GF generally has a pretty horrible reputation at badcaps.net (and yes, I've seen a few failures myself, including one that caused the PSU to destroy the motherboard, and yes, failures -have- been reported on corsair CX PSUs). I class them as 3rd tier - same as ChengX, CapXon, 12KJ, etc. GD series were used more often on motherboard VRMs, and not in ATX power supplies. These days, though, all of the ultra-low ESR series (including Nichicon HM and HN and Ruby MBZ/MCZ) are discontinued, and polys have pretty much taken their place.
    No wonder it doesn't work! You installed the coils backwards

    Actually, I've been seeing GC on some ECS-made motherboards, they held up fine for > 5 years (24/7) easy.

    GD I encountered in monitors and power bricks, and they didn't seem to mind the very restricted airflow and proximity to heat sources... I don't think their ESR is prohibitively low, especially since it doesn't go below 10-11 mOhm, and is typically ~19-23 in the most popular can sizes.

    How come that here you all never sticked a thread/chart/spreadsheet about personal caps ratings/preferences (without the "noise" of badcaps and the like) over the years?

    With green heat shrink tubing? It will be a perfect match for that famous green tape.

    Not enough of our user base is DIY-oriented. Even if they were, making blanket statements about quality and imposing preferences and attitudes on others would possibly lead to undesirable results (remember, we are very knowledgeable here, so our words do carry some weight and authority), since pretty much every situation is unique.

    Also, if someone was to infer an apparent build quality measure from such a thread, it could potentially be unfair to the brands and manufacturers. We're still waiting to see any significant statistics for Capxon, Samxon, etc, and we can only make claims about "Tier 4" and below - BH, Jee, Canicon, Sacon etc. They do suck big time, no matter what anyone says.
