-- Power Supply Is Dangerous? (http://archive.tivocommunity.com/tivo-vb/showthread.php?threadid=96450)

Not to mention, it's a switching power supply, so those heatsinks sticking up from it are at a pretty high potential with respect to ground (80V or so). Plus some of those capacitors are at very high potentials (I think one of them has close to 150+V on it in normal operation - basically rectified AC).

And especially careful because the bloody Molex connectors can be a real pain to remove, and if you dont' stop yourself in time, your hand will fly into the power supply...
