I am starting to see su'scon caps used in high end power supplies on the secondary side. though they are known to be bad, are they still bad now as quite a few reputatable manufacturers such as enhance are using them together with teapo caps?
Are Su'scon caps still bad?

Re: Are Su'scon caps still bad?
IMO they are slightly worse than Teapo. I see them in lots of power supplies these days though.
Teapo can actually be pretty good when kept cool. I saw a ~15 year old Teapo last friday on a jukebox power supply, still good after years of 24/7 useOST are close to Teapo also.
Seems there are a lot of higher end power supplies using middle of the road caps. PC power and Cooling uses Teapo, Sparkle uses Teapo, Jamicon and sometimes Fuhjyyu, Enermax uses Su'scon and some others.
I was very surprised to find Fuhjyyu caps in my old Vantec Stealth power supply, still good after 5 years of daily use. I guess cooling makes big difference, along with the amount of pre-cap filtering (inductors).Last edited by Maxxarcade; 06-03-2007, 06:15 PM. -
Re: Are Su'scon caps still bad?
thanks maxxarcade for your reply.
does that mean if the PSU is equipped with a high-speed thermal controlled 120mm fan, the caps with last?
i need to confirm cos i just realised that my new silverstone 750W PSU has teapos and su'scons in it.Comment

Re: Are Su'scon caps still bad?
I left all the cheap caps in the Sparkle power supplies that are in my servers (24x7 duty), but I check them at least every 6 months. I was actually considering bypassing the speed control on the 120mm fan so they would run cooler, but haven't gotten around to it yet.
For a 750W PSU, they probably have good filtering in place, and you would have to work pretty hard to strain it. My Vantec was 520W, and even with 6 drives, Athlon 64, and Geforce 6200, it lasted 5 years, and is still being used in my PC at work. Though it does have 3 good 80mm fansComment

Re: Are Su'scon caps still bad?
The answer is no, you cannot just assume if the PSU weighs a lot or has a 120mm fan that will automagically make a questionable quality cap acceptible. However, it depends on the placement in the circuit and specific cap (size, specs, and model/family not just brand), and the load on that (rail?), how long the cap will hold up. The odds are in your favor if you have bought an excessive PSU (at 750W) and aren't running it anywhere near that output level. We don't have this info for your Enhance so due to lack of info it's probably an early failure point, but whether you find the lifespan acceptible is another matter, it might run years.
I doubt you really want to bypass the fan controller entirely, as it may run quite fast/loud. Consider modifying it to run a little faster instead.Comment

Re: Are Su'scon caps still bad?
my previous antec psu died on me after about 2 years of usage due to leaking fuhjyuu caps. if su'scon caps is really of questionable quality, will it still affect the lifespan of my new silverstone psu? to me, i want reliability and durability. fuhjyuu vs. su'scon, which can hold up better in psu environment?Comment

by momakaI know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

by momakaNormally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

by eryjusHello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

by Paxman_SwedeHello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and...-

by captain150I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...-
