Re: My new Seasonic has questionable caps.
I am getting really tired of repeating myself because you want something to be there that isn't. The short version one more time. When load testing units very few units with questionable caps survive load testing, as such there are very few cases when the unit would be recommended based on my testing so that the capacitors would come into play as a reason for the unit to fail long term sicne the unit has already failed thereby nullifying any capacitor issues. The best examples of this not occuring are with Turbo-cool's...

Re: My new Seasonic has questionable caps.
<shrug> Sure </shrug>
If the person who provided the unit wants to provide that information they can...but I am not releasing it because I really rather keep my contacts.
Someone who worked for NASA surely knows that you can't do things like that....Leave a comment:

Re: My new Seasonic has questionable caps.
THis all started because a friend asked me to look at a recapped unit. After some interesting results there.
I looked at some units that someone else who was pulling from service because of bad caps and wanted to recap to redeploy. The units that were recapped failed originally because of the caps. The units where then recapped. Once tested they failed. So after going "gee that's funny" lets get some brand new units and see what happens. Those were tested and they failed........and it was...Leave a comment:

Re: My new Seasonic has questionable caps.
Right for a decent power supply in that is true the BOM is about that range (and when I say decent I don't mean high quality.)...but that isn't the only cost that goes into a product. People who have always been employees and don't run business's always make the mistake of thinking items should or can be sold at the cost of the components. That simply is not the case.
I know for a fact that the additioanl cost for moving from Teapo to Nippon Chemi-con on an upcoming power supply was $3-5 per...Leave a comment:

Re: My new Seasonic has questionable caps.
I could do that and there are lots of things I would like to do in each review that I don't do because the issue as it stands is that the least read page per article is build quality followed by transient testing. Right now I am lucky that those little excursions of mine are tolerated but they add real man hour cost to the review. To expand more I would have a hard time justifying to the budget why we should buy additional equipment and spend more per review to do them when it doesn't generate the additional page hits.

Re: My new Seasonic has questionable caps.
Yes the original 510 ATX I used to tune everything was good to go visually and on the oscilloscope. Though it really needed to be cleaned.
Like I said I really can't honestly ding PC Power and Cooling for using Teapos because they do last. I can comment that they use them but dinging them would be dishonest.
There is one other thing at play here that is probably missed. I don't have the same the luxuries you guys (ie anonymous posters) do. I can't spout off random crap about companies or their...Last edited by Spectre; 01-24-2008, 12:48 PM.Leave a comment:

Re: My new Seasonic has questionable caps.
Actually I already covered already and it I replace failed units because of exactly what I said. Recapped power supplies that I have load tested have failed (ie gone out of specification) in less than 12 hours. Therefore, recapping a unit that will fail again because the unit is fundamentally flawed is not the appropriate solution to the problem. The correct solution is to use a proper part.
Right. Ok if everyone here does failure analysis down to the component...Last edited by Spectre; 01-24-2008, 11:26 AM.Leave a comment:

Re: My new Seasonic has questionable caps.
Let's see here what I actually said on teh subject not what you seem to have imagined on the subject:
The bolded part there is the important part.
That's great but you are still wrong. I never said a single item costs over $50 that is your strawman. I said the BOM on a good power supply is going to be close to that and that doesn't include the rest of the requirements to get a unit to its wholesale price....Leave a comment:

Re: My new Seasonic has questionable caps.
And that stack of units is made up of how many units out of how many sold? What percentage of those units are represented by what Brand/model? In that breakdown what is the percentage of each capacitor brand?
I think what you will notice if you quickly run through those is that you have a small percentage of units out the total sold that are made up almost exclusively of a few models of power supplies which consequently have only a few brands of caps that have failed and that those failed units have other...Leave a comment:

Re: My new Seasonic has questionable caps.
No there isn't but I also can't bag a unit that passes because it [I]might [/I]die in 3 years because of the capacitors used when everything else about the unit is fine. That simply is not honest, or fair as an assessment because we can't prove that it will die or even that it is at a greater risk of dieing since there are certainly a large number of units with certain questionable caps that last a very long time while there are units were good caps don't last a long time.
Seriously, if you think back in...Leave a comment:

Re: My new Seasonic has questionable caps.
Forgive me doing this all in one but there is a bunch of junk in this thread.
Seasonic has used OST/Teapo etc on their lowend units for some time now. In fact if the unit is an Antec Seasonic such as the NeoPwoer you can gaurentee cheaper caps since its Antec costing the unit down.
Yes they often use NCC/Rubycon/Matsushita on their higher end models under their label and those of partenrs who do not cost down the units.
No they don't.
