Please open a single thread for a single query and wait for responses. In other words, don't create multiple threads for the same question.

Btw, to answer your thread heading, go to the underlying link. Fill it to the best of your knowledge and hit the calculate button. It will tell you how many watts your system needs -

The Cooler Master Extreme Power Plus RS-650-PCAR-E3 is a piece of trash that is unable to deliver its labeled wattage.

What is the make and model of the 2GB graphics card? Without knowing that, I can only guess as to if its enough or insufficient.
