Do i need a new power supply?

[Ravonz]

Hey guys. just need some information since i am confused. My pc specs are Gtx 1080 G1 gaming ediotion. i7 6700K. 8GB of RAM. A 550w power supply and my motherboard is a gigabyte H110m-H motherboard.my fps in games like battlefield 1 is sometimes a high as 110fps and as low as 50fps. i know for a fact i should be staying at above 100fps for most of the game. it is running at 1080p on ultra graphics, and the fps drops that low? im really consierding buying a new power supply because that the only problem i can see right now is that im not getting enough power. what do you guys think? thanks.
