I don't know what all the fuss is about power supplies. In my 15 years of being around other people's computers, building my own computers, and building computers for others, I never had trouble with the cheap power supplies I used, except for the rare failed ones (cheaply replaced), and only once did I see a massive (i.e. complete) failure of a PC which might have been a power supply thing (but not from a voltage fluctuation since the other computers form the area felt nothing, most likely a MB short circuit as I remember, not mine).
Since I never go for a "max theoretic power plus 200W" philosophy, that I see is common, I barely reached the 500W barrier recently. Who needs more for a dual core, 2 Gigs of RAM, a couple of HDDs, some random optical drive, and a good enough GPU combination anyways?
I always thought the PSU reviews are full of it. Cheap PSUs worked fine for me.
