I recently needed to order few more PCI USB controller cards and I had a few laying around already(I need to connect many USB cameras). What surprised me is the difference in design and more importantly missing capacitors on the cards that I recently purchased(Asonic). They are from different manufacturers so different design is to be expected. But what I see is clearly a much poorer product, those recent cards. The price was the same.
Here are some pictures:
So my questions are, what can I expect performance wise?
What's the purpose of those capacitors?
