Ok so this is my first time building a computer and I am following a model guide I found online. I did my research on the components and everything seemed to have a good review. However, when I started digging into the the Graphic cards information, I noticed it recommended
a 750W power supply, or close to that, when the guide I was following said 550W would be plenty. I really need help with this. By the way, it is not a big deal if I need more power as I would gladly buy but I do not know if the same power supply except bigger power would still be
compatible with all the other stuff.

Keep in mind, I am not familiar at all with this, so I may look dumb.

All help is greatly appreciated.

PS: The graphic card I want goes off sale tomorrow and it goes back up to its 500$ price.
