Yeah the PS is a whole other story too. I used to have very inefficient 
ones. Probably produced more heat than actual power. I do think the 
80-plus thing is a good idea, it does seem to be for real, again only 
from reading some reviews around the net (haven't used any myself). I 
have a Neo HE from Antec, which was their precursor to their 80plus 
PSUs. They do say that the efficiency drops off somewhat badly though 
when the system isn't under load, which would be most of the time for 
people here who run their systems 24/7. Does the 80plus mean it's at or 
above 80% efficient all of the time or just at peak power?
