Computers *often* have sleep modes but not always. I personally turn off the power saving modes because they can interfere with downloads and burns if they kick in right in the middle of something. And power supplies use about the same amount of energy when they're on regardless of what the computer is doing. You can't expect a power supply to spool up every time the hard drive comes on. The power has to be available on tap at all times. Let's do Goodbar6 a favor and paint the darkest picture reasonably possible of his roommates' computer use.
power supplies suck in the power they need, they aren't pushed to the maximum...they don't have to 'spool up' as there are no moving parts. If your computer is only using 5w of power, that is what the power supply consumes (maybe a little bit more to compensate for heat losses. If the power supply was always consuming the amount of power it is rated at, then all of these power saving features would be completely useless.
This is about the only thing I could find online with numbers measuring a computers power consumption:

He doesn't really give much info on whether the 'steady state' measurements were of the computer in a power saving idle mode, general usage, or a combination of both.
