Does my power supply have enough power for upgrading MSI r9 380 4gb into MSI gtx 980 ti?

I currently have: i5 4460, MSI r9 380 4gb, AsRock H97 Pro4 motherboard, 1tb harddrive, 1 diskdrive, 8gb of ram and 550w powersupply. Nothing is overclocked. Could i upgrade my gpu into MSI gtx 980 ti or would i need to get larger powersupply for the new gpu. Or would my cpu or something else hold back the gpu if i upgrade it?
