Re: Upgrading Silverstone SX600-G PSU Caps

your caplist has no diameters.

Re: Upgrading Silverstone SX600-G PSU Caps

Why would you do that with the Rubycon?

Yeah I guess I'll leave this one be to favour or your local stores as for 2200/16 I only got 10x30 mm at the moment. And as for 6.3 I got some 20mm samples, 2700, but it is not worth dripping into multiple orders for you.

As for Chemi-Con range, have a look after KYB, KZN, KZH, KZM series, those have best energy density and being latest series, longest rated lifetime. Rubycon and Nichicon does not yet have anything comparable, Panasonic maybe those FR.

stj: diameters are pretty obvious. Taicon is 12,5. Bigger SC D10, smaller&SH D8. The smallest will be D5.

Re: Upgrading Silverstone SX600-G PSU Caps

I thought I was supposed to leave the Rubycon? I just removed a little bit of the white goo that was next to it and holding in place a thin plastic sheet. I thought I could leave the Rubycon and just add some more white goo and the sheet to keep it like it was, but maybe I'm mistaken and misunderstood on the Rubycon.

Sorry about the lack of diameters, didn't occur to me at first that I should add those, but I see now how that could be helpful information. I can add if needed.

Okay, so in regards to the stock you have, it sounds like you don't have the ones I'll need for all of them? I would still be glad to buy what you do have as I really appreciate all the help. I'll try and find the others in the Chemi-Con series that you have recommended as it sounds like they will be the only source for some of them.

If there is anything else I'm missing just let me know. Thanks

Re: Upgrading Silverstone SX600-G PSU Caps

Well I don't understand what do you want to do with that cap, just leave it be in peace

You got Digikey in there, most likely Farnell too. Not sure about the geolocation of all these companies…maybe RS components or distrelec too.

Re: Upgrading Silverstone SX600-G PSU Caps

Ahh, okay. Yes, sorry for the misunderstanding. I'm not going to touch the Rubycon, I'm going to leave it there.

Thanks for all the help and information. I will update as I make progress on the project.

Re: Upgrading Silverstone SX600-G PSU Caps

Here is what I've found searching around for replacements. These are all Chemi-con, and in stock at Mouser. These look like the right ones? I've matched the voltage, capacitance, and size, and went through and found the longest life available in either 105c or 125c versions.

Re: Upgrading Silverstone SX600-G PSU Caps

I think that you can replace the 220/16 with for example KZM 470/16. It will be just OK. These high-temperature caps usually have higher ESR, they are more for automotive.

Ahh, okay. Thanks for that. I will do a little more digging and see what I find.

One thing I wasn't completely sure on was in regards to ripple and ESR. If I understand correctly from what I've read, it's okay to have a cap that's rated higher in ripple than the one it's replacing. As far as ESR goes though ideally I want low-ESR caps because of the application being a power supply? Or am I not understanding that correctly?

Thanks

Re: Upgrading Silverstone SX600-G PSU Caps

Generally, yes. Usually close to the original. It is not so important to strictly keep the dogmatics abour ESR always same or lower, in SMPS usually capacity/ripple current playes greater role. If you are within reasonable range to original, it will be OK. There are different series from Chemi-Con now, KZN have great ripple current while higher ESR. I think KZH have lowest ESR but not that high RC and life.

But often different factors are important too (like how fast is the cap to respond on the ripple, which is also function of above parameters). If they count with it in the design, they may use very low ESR caps, today mostly polymer caps. Makes sense especially for synchronnous rectification. But those have lower capacity so they are often combined with wet electrolytics. Polymers are generaly fine, with few exceptions (Lelon), that's why we only swap wet electrolytics.

Re: Upgrading Silverstone SX600-G PSU Caps

I found a KZM for the 220uf 16v one. I reviewed the other ones and it looks like they are all listed as low impedance, and have higher endurance/hour life.

So my plan is to buy all of these from Mouser, since they are all in stock, then I'll get them in and start swapping. I'm still working on the fan, I tinkered around with a low profile 92mm unit and did get it to fit, but only with removing the plug and line in section. So I'm not exactly sure how I'm going to approach that part just yet.

I have a feeling that whatever fan setup I come up with is going to be run off the motherboard, with it's own custom fan curve in the BIOS. The controller inside the PSU is not capable of running a 12V fan apparently, and I don't like the idea of the fan sitting their idle and not running at all, I guess I just don't understand that logic of not having the fan run at all. I know it's for noise, but it still seems like it should run slowly at a bare minimum.

Re: Upgrading Silverstone SX600-G PSU Caps

Bringing up an old topic, but might be useful as a followup.

The unit I have, had a noisy fan and later from reviews I found that this has a questionable choice of capacitors, I was curious to find a replacement for those.

Heres the details so far I have for my unit.



The difference with OP is that NCC was changed to Rubycon and Taicon to Teapo. Looking for replacements for Teapos now, assuming the Rubycons are OK. Any thoughts on Suncon (pic)?

However I think there is another capacitor that reviewers and OP missed and that is between the daughterboard with fan controller below white/blue blob in the middle-back part of the board. I'll have to desolder it to find out what it is. It looks like a small black Teapo, but I can't see any numbers due to whatever is coating it.

Also another question, there are aluminium caps with red text (pic, behind electrolytic, on the daughterboard), with three lines of numbers:
330 or 380
16CP
562

I couldn't figure out what these are, perhaps someone can comment?

[stj]

Re: Upgrading Silverstone SX600-G PSU Caps

red text are polymer caps.

[Behemot]

Re: Upgrading Silverstone SX600-G PSU Caps

Look like Teapo CP.

[Ingram]

Re: Upgrading Silverstone SX600-G PSU Caps

Figured out what the unknown cap was. Rubycon 35V 100uF ZLH 3M1505 105C PET underneath a piece of heatshrink.

[Ingram]

Re: Upgrading Silverstone SX600-G PSU Caps

Since I need to order from Mouser anyway, I also checked caps from there. Luckily OP-s choice is still relevant.

Here is what I came up with
https://docs.google.com/spreadsheets...it?usp=sharing

I also went with KZM for 220uF, however I figured that for 470uF a better fit in terms of the diameter would be KZN instead of KYB. One probably can fit a 10mm cap there but it will be tight. Rest is the same. Should be good, right?

[Behemot]

Re: Upgrading Silverstone SX600-G PSU Caps

Got everything but "F" column on stock. For less than half they ask from expensivouser.

[Ingram]

Re: Upgrading Silverstone SX600-G PSU Caps

Do you have anything comparable to the "F" column? It's out of stock in Mouser as well.

[Behemot]

Re: Upgrading Silverstone SX600-G PSU Caps

It is D8 right? I just received 470/50 but those are D12.5. IIRC it is on the -12 V rail, regulator input so the chances are there will really be voltage lower than -16 V. Smallest usable I have is D10x20 mm, KYB 1000/25.

[Ingram]

Re: Upgrading Silverstone SX600-G PSU Caps

It is D8 indeed. D12.5 will be definitely too big, whereas D10 will be tight, touching a heatsink.

Meanwhile, I found replacements for the out-of-stock ones from Panasonic FR series.

rubycons are fine. they can stay. the suncon is fine as well. its actually a sanyo cap.
