Have you *tried* to find a small power supply lately? I had to go 
looking in early December and the lowest powered PS I could find was a 
350 Watt unit. I ended up with a 400 watt modular so I would not have to 
deal with a dozen unwanted wires.

I spoke to an engineering representative of SilverstoneTek at CES and 
put a bug in his ear about this. He seemed quite interested and mildly 
surprised at the low levels we generally run at...well below the 80% 
efficiency band for most power supplies. Hopefully it will result in 
something. (Just remembered I promised/threatened to email him, and I 
know where his business card is..will do that tomorrow.)
