Some time ago, I bought a 7-port USB hub from Plugable, and it came with a pretty decent power supply. Most cheap hubs provide a correspondingly cheap wall-wart which will only give half an amp of current. But this one from Plugable was a proper beast that gave me 4 whole amps of current! Wow! Until it broke after 6 months of use.
Plugable was really on the ball, and immediately sent me a new power supply. So props to them. But I was curious about what went wrong in the faulty supply, so I popped it open. Here are the pics:
