Are Taiwanese capacitors STILL junk? (PSU)

[Winterseed]

No doubt they once were, many brands at least. Also no doubt solid caps from a good brand are preferable every time. I just ask because the Thermaltake Toughpower XT 775 power supply comes with a lifetime warranty here in Australia http://warranty.thermaltake.com.au/ and uses some Jun Fu liquid electrolytic caps according to Hard OCP http://hardocp.com/article/2010/04/13/thermaltake_toughpower_xt_775w_psu_review/3

Thermaltake offer a 5 year warranty on other products which implies that their lifetime warranty exceeds 5 years, unless they maybe just decided to change the wording at some point. Either way, it should be covered for at least 5 years. Would they offer such a generous warranty without near-absolute confidence in their product? Maybe the Jun Fu caps in this PSU fill a role where even bad caps wouldn't be expected to fail? I'm not knowledgeable in electrics.

I'm hoping for some discussion based on current information and recent experiences, not knee-jerk reactions from bad cap PTSD. From the brief research I've been doing, the problem was poorly formulated electrolyte. So far I'm not seeing evidence that the problem still exists, but I am seeing advice to avoid liquid caps. Is this advice simply redundant now? Do modern liquid caps still prematurely fail often enough to worry about it? Have some brands improved and others not?

(I bought the PSU mentioned above, if you hadn't guessed. For my brother's rig and my own)

There's no easy answer to your question.

Statistically, any PSU that has concerns raised by a professional reviewer may have problems. Unless he's VERY CONCERNED you might easily be just fine.

I suspect this will mostly translate into a reduced lifetime compared to a higher quality product, thus I expect your Power Supply to last Five Years and one day exactly.

I wouldn't be too worried about it.

Ha, five years and one day. xD I wouldn't be too surprised.

Thanks to the warranty, I'm not worried. I'm really just curious why it took so long for me to even find out that the bad caps problem is possibly a thing of the past. It might be a problem with the way I look for information. I started researching to build my first PC nearly a year ago and came away with the overwhelming impression, from every source I could find, that liquid electrolyte caps are a deal-breaker if you're serious about building a reliable system. Maybe serious builders and reviewers aren't giving them a second chance, which I would understand.
