Will be used for browsing internet, playing HD movies, some light gaming (nothing like metro last light). The SSD will be used to boot the computer and it will be running on Windows 7 home. I also have another HDD 500 GB drive that will be used to save pictures and documents.

The total for this comes out at about $534 and i need it to be no more than 550$. Another thing I've always been perplexed on is how big should my PSU be? Say my system was to max out at 300W should I get a 500W PSU? That would make it more efficient energy wise rather that getting a PSU that had a max of 350W? Plus wouldn't it allow for the system to run cooler or would there be a lot of energy wasted on heat? One last this I'm hoping that this system will last at least 3 years minimum. I apologize in advance if this is difficult to read.
