My first thought is "that explains it" - but it really doesn't! Lot's of decent and well constructed devices are "made in China"; makes me wonder where it was designed, or manufactured; that board seems like a cut-rate savings method. Obviously, it works - but if I opened up a device and saw that, I would have my doubts about it. Any reputable company would do a re-design and use an actual board there, not something cut-down like that PCB is. Of course, this now makes me wonder if similar methods of production have found their way into a number of products on the market today.
/I also must note that if I paid a lot of money for such a power-supply, and then opened it up to find that kind of workmanship, I wouldn't be very happy...
