I'm not wanting to buy one power supply that's not going to be enough for when I add more stuff to it later on. What would you recommend for this?

It won't hurt anything to have a power supply that's rated for a significantly higher capacity than you're currently using. A quality but still budget-friendly power supply in the 650w range would be the 80-PLUS Bronze rated Rosewill HIVE-650, which currently retails for $70.

Anything over 400W is good. 400W is plenty and gives good headroom for future smile.gif

a bigger psu has no negative effects besides a bit more outta your wallet

if a pc requires 300 watts it will use 300 watts regardless if the psu is rated to output 300 watts or 10.000 watts the only real negative is that drawing 300 watts from a much bigger psu puts you in the bigger psu's worst level efficiency curve

the 80plus testing tests a psu at 20,50 and 100% loads it needs to meet a specific criteria within those tests to get a cetification but running at a rediculously low percentage of a psu's capacity really burns the watts as oposed to whats being delivered

if you wanna add a ton of stuff later i would suggest something in the 500 watt range with is more then enough for a typical system
650 watts if you wanna add another graphics card and goodies or 750 watts if you wanna go for a high end system with 1 or 2 high level cards with added cooling like water
