Answer 5

if you plan on having a nice vid card and a 2ghz processor or better go with a 400+watt. If its an AMD motherboard get a 24 pin, if its Intel get a 20 pin.. Anything less power a 300-350 will do..

Answer 6

Just remember, you may always upgrade components later on. It is better to have more watts that you need, because you are fine if you dont use them, but you will have problems if you dont have enough. I would go with at least 400W to be safe, unless you are really decking out your system.
