Considering this platform, nothing is surprising except the +12V ripple.

Sure? The Fuhiyu caps at the very beginning should have been quite bad. On the other hand, back then, warranty was 3 years, so dead units after 4 years wouldn't make it back to the company.

Yeah that's the point, that he misses...
Especially in the older Topower Units, the caps may have failed from time to time. And also some later units, there are some pix of blown caps in the Feedback thread of Hardwareluxx. So they actually may fail.

But still I think the japanese cap hype does nothing good as the fan is the most common thing to fail...
To be mean: With this unit, the fan will probably fail first (when it's not some other thing), while in the be quiet unit the fan will last...

So we should probably stop to look just at the caps and see the whole unit. A PSU isn't just made of caps, there are other components used as well. And they may (or may not) fail...
With most units, the fan is the weakest spot so why bother if it has japanese caps or not?!

A ball bearing fan isn't exactly cheap crap. It may be a bit noisy, but it's not like it's a sleeve bearing.

I haven't said that Chris (the most important part), however caps are important, so much so that the P10 is filled with NCC electrolytics (how's that for an arguement? ).

I certainly would complain, if I'd see non-Japanese cap in a high-end unit, especially if it was advertised to have only Japanese ones.

In lower-end, especially if fan spins fairly fast@idle, it doesn't matter a whole lot. I may even swallow presence of Jun Fu at extreme low end, if fan is really fast (like CWT GPA, where it does 1000-1100 rpm@idle).

But that unit would be fairly loud. So why buy something like that? Especially when you know that most people care about the noise and it's the first thing you'll notice about a PSU...
