And you should have read that I noted that power requirements are not 
available.
The question was 'what is the difference between a 240 and 220'. The 
table explains that. The user-entered data shows that a 9500GT will do 
HD without problems. In fact anything over that may well be 
overkill...but the 9500GT is now "obsolete" and probably not available 
(just like power supplies under 400 watts!).
