Infrant/Netgear ReadyNAS NV+ PSU fails

Top of PSU - the insulation on the inductor is not paper

Bottom of PSU

This is a PSU from a Infrant/Netgear ReadyNAS NV+ system.  The PSU likely failed because of design problems instead of faulty components; the failure seems to be a common event on certain manufacturing batches. 

Notable features on upper picture: 3 bulged capacitors, 1 inductor with burned insulation.  Notable features on lower picture: signs of overheating, jumper wire in solder.

This started as a burning smell and extreme heat coming from the DVD drive, and ended up with what you see above.  The PC power supply that powered the computer this drive was in failed some months after.  Credit:  stsm.
