careful, running a couple pc's with 1000w power supplies could possibly get your house raided by leo's looking for pot plants... seriously. imho i think we need to protest any power supply above 700w and make the manufacturers design more efficient computer parts. do you know how much power 900w is? that could drive a subwoofer twice as loud as it needs to be to blow your eardrums out. i guess my only salvation is the fact that they cannot make power supplies larger then 1400, at least in the US. that, and the fact that 900w supplies might be nice to run an integrated amplifier on the pc but other then that.... i dont know its just plain a lot of power for surfing the internet
