series 1 tivo's had a LOT of problems with power supplies.. power supplies are usually skimped on in set top boxes (consoles, tivos, etc), because good ones are very expensive. when you have a release of this magnitude, there are going to be some bad ones.
not trying to justify for MS here, but just saying.. the poster above who said he hasnt had any probs, he prolly won't if its worked so far.
