I know you told us not to say this, but seriously, you really aren't going to get a CPU, GPU and wattage for that price unless it's complete crap.
If you did get all that for that price, you would probably not be able to play they games, even on low settings.
You're going to have to up your budget a bit. If you're a kid, why don't you ask your parents to get you some parts. It's christmas dude, I'm sure they would get you parts that are more expensive than that.
