I'll be short and to the point.

A GT 640 is not really a "gaming" grade video card, it's not going to perform well in modern games, it's ideal for those who enjoy HD movies and videos.

As for the Power supply, don't worry so much about the Amps it puts out, it's all about the watts in most cases.

For example, a small PSU can handle your 640 with ease.
