Whats the max amount of wattage my computer uses?

Well, a couple weeks ago i got a new custom computer and i am continuously wondering what the maximum amount of wattage my computer needs and so i know that when i upgrade, im not gonna bust my PSU. Here is my list of parts:

CPU: AMD FX-4100 3.6Ghz
GPU: AMD Radeon HD 6670
Motherboard: ASRock N68-VS3 FX (no ucc)
RAM: 2x2GB 4GB DDR3 1333 Gaming Grade Memory Module
HDD: 500GB 7200RPM
Optical Drive: 24X DVD RW DL Optical Drive

This might seem a little unspecific cause i didnt want to take apart my computer to find it so i used my part list.

Your rig most likely uses around ~200w.

Thank you Motopsychojdn it came out as about 333 watts... and i have a 700 watt power supply, the place i bought it from went a little overboard with it but i suppose it will be good for upgrading.

I like a bit of headroom for a Psu, as long as your model is a decent one it should last you a few upgrades,
If you know the brand/model, google it for reviews and see how other users and review sites feel about it

About 300W sounds pretty reasonable.
