Well guys I'm following a tutorial on youtube to help me build my first build and I'm using everything he uses to make it easier on me to build it. I'v done my research and I was thinking I could slip in a better Graphics Card a Palit GTX 780 super Jetstream which performs better than the Default 780 but with higher Power...
The build I'm following is power sensitive as it only has 550W of Power as all the components (Power supply, Fans etc) require low amounts of power allowing the default 780 to run with 550W. As I'm increasing the power consumption will I need to increase the power or is it ok.

Please increase that power supply. Never get really tight: PSUs lose performance over the years, and start losing capacity. It might work now and not power up in a year because the little capacity it lost was what made the difference.

Get at least 650W to be safe for sure.
