This is a legacy list. It is no longer being updated.

Lol why do you call them WAPANESE capacitors?

Wannabe Japanese because they are still made in China due to the Chinese Import tax.


And it doesn't matter at all for the quality of the PSU, its at most the icing on the cake.

¿what country are you from, what are your system specs and how much do you want to spend on a psu?

Not many options.

Everything else is more important and should come before the caps.

 

You want/need an independantly regulated unit with a nice fan and all protections we have today (OCP on minor rails, OTP, UVP on +12V and so on) before "nice caps".

 


so the Question for you is: 

Would you prefer a Xilence Performance X wich looks like that:

https://img.tweakpc.de/image/dsc-4720-custom.dQt

 

Or would you rather have a Seasonic S12II Bronze based unit.

 

 

So what I'm saying is that caps are overrated and it depends on the design, layout and you'd want other things first anyway. 

Though the Performance X uses a couple of Japanese made caps in my case as far as I can see it. Those Polymers seems to be Nichicon...

Yeah that's what I've heard you can make the worst capacitors last if they are cool enough

no, its basically a lower end version of the TXm we have today.

I was talking about ultra low ESR wet electrolytic caps specifically!

You know something like Nippon Chemicon KZG/KZJ, Panasonic FJ, Nichicon HN and all other "Ultra Low ESR" capacitors that were thrown out by most manufacturers. And replaced with Poplymer Capacitors...

 

Those ones that have high water content, thus lowering ESR and increasing the reaction and decrease lifetime and reliability...

 

The Nichicon HN for example only has 10mOhm Impedance at 10x25mm and 2900mA Ripple Current - and are only specified for 1000-2000h lifetime.

 

Teapo SZ seem to have higher Impedance of 14mOhm and only 2318 for 10x20mm types...

That's like double the Ripple Current and less than half (or rather 1/4th) of impedance of a similar Teapo SC,

how far the next hot thing is and thus how cool the caps stay, how much ripple the cap does have to endure, frequency, how much redundancy...

That's partly true, but not completely.  You would also have to over-spec the capacitors a lot more than you would with quality parts to prevent them from being stressed too much (even if they're kept ice cold), and make sure the circuit accounts for the poor spec tolerance of the caps which can have a variance of +/-20% or more from their rating.  By the time all is said and done, it would have cost the same to just use the good parts.

 

The cheap power supplies with poor quality caps remain cheap because they don't account for poor tolerance or anything else mentioned.  They're basically just thrown together as quickly as possible, the factory might test a few samples to make sure they turn on without blowing up out of the box, then they'll crank them out with a production cost of $2 to $3 a piece (no joke there by the way - an OEM actually made that offer to us a while back).  So when you buy a "400W" power supply for $20 and free shipping, the truth is you're paying about $15 for shipping and $5 for the PSU.

Bit off topic, but when I worked in a liquor store a bottle of whisky had about $22 alcohol tax on it (based on alcohol content). Cheapest bottles started at $30 which includes another 10% (~$2.70) sales tax. So a $30 bottle of scotch would be about $24-$25 tax. That leaves about $5 to produce it, bottle it (bottling is quite expensive), label it, ship it from Scotland to Australia, distribute to stores, and include a profit margin for the store... And customers still asked me if it tasted alright.

Hello, I have A10-7870k atm running on LC Power 600(know it's crap but i don't even have GPU) so I'm getting RX570 4GB in a week and I gotta get new PSU, will be running this CPU until spring, waiting 3rd gen Ryzen 5 to upgrade the whole platform.

99% I'm getting bequiet! pure power 10 or 11 if I can get my hands on 11(is it just gold rated pure power 10 basically?) bequiet! PSU calculator tell me that 350w pure power 11 would be enough but it's best to get 400w one, my question is if I should get 400w or 500w one, I use PC mainly for WoW and internet and i won't upgrade RX570 at least until september 2020 when next expansion will come out, if I end up getting something power hungry at that point I'll get better PSU, that's not problem, I'm just a bit sceptical about putting RX570 and Ryzen 5 on a 400w PSU, here in Serbia I will buy imported stuff from Hungary and 500w is 25% more expensive than 400w, so if 400w if enough I could add another fan to case or get better quality SSD, something along those lines, I am aware of there being normal and semi-modular versions of pure power 10/11 but I don't really care about it being modular, just need it to do the job.

Would recommend going with something in the 450w range for the system and GPU you will be running. It's hard to find units of good quality at lower wattage than that (350w range) but you don't need anything more than 450w.

yeah, kind of a what I was thinking, I found these Tier 2 stuff, 500w normal is 65 euros, semi-modular is 70 euros, gotta contact seller for price on 400w ones, but normal one is almost 20% cheaper so it should be max 55 euros, they don't make them at 450w afaik, and everything else in tier 2 is 100+ euros here in Serbia which is noticable difference in price

Too high tripping point for the OTP. Stuff can start melting. And some of the review samples died before tripping OTP. 

The higher wattage G3 versions are also among the loudest PSUs on the market. It doesn't factor into this tier list, but it's something to be aware of.
