if you go higher it'll help ensure that you won't have to upgrade it with your computer, but more power=more heat, and more heat=more fans, and more fans=more noise...

Go to and drill-down into the Athlon Processor link and look at the recommendations. AMD provides a rather larger list of recommended & tested P/S, M/B....etc. You will be able to make a more intelligent choice of your own.

300 watts should be plenty for the system you describe, but if you want to go any higher with your processor, any more drives, or a newer video card you would want to look into a power supply upgrade.
But power supply's are easy to put in and out, so it's not a big hassle if you have to do it later.

I suggest a minimum of 350 watts. More impprtantly you need to have at least 180 watts acropss the +3.3 and +5 volt lines collectively. Inadequate power is the most overlooked part when it comes to instability, Get more than enough and eliminate it entirely.

Get something around 400 watts. Everyboady keeps upgrading their power supplies every 6 months, by the end of the year 400 will proabably be what you need to run AMD's fastest processor anyway!
