Need help with PSU and wattage.

How much wattage does a Q6700 and a GTX 650 (1gb) need at full load?

The rest of the system specs arent much, just 3 gigs of ram..160gb hard drive..and a CD thing.

The pc currently has a liteon 300w in it and is running fine idle and using the internet...but im a tad afraid to play a demanding game like crysis 2...because i dont want my pc to blow up.

I am having an Antec VP-450 put in soon...i dont know if 450W is enough or not....the CPU tends to go at 100% usage when playing demanding games.

    Yes the Antec 450 is more than enough.You won't even come close to max with those specs.

    The CPU and card will pull 160 to 170 , the rest of your system not much at all.

    Good idea to get rid of the liteon PSU.
