It's unlikely your total system power use would exceed 400 watts. If your 550W is a high quality model and not too old you should be able to use it. If you want some headroom or your 550 is not that great and you need to replace it then a good 650W model would be more than enough. List your 550W brand, model and age for a better evaluation. If it turns out you should get a better unit there's plenty of guys around here who know what you should spend your $$ on who will help you.

Typical power draw on a GTX 1080Ti is around 250 watts with a max of 300 watts (one 6-pin, one 8-pin, and 75 watts from the PCIE Slot). The rest of your system isn't going to draw 250 watts, so while you should be fine with a quality 550 watt unit, I'd probably opt for a new (quality) 600-650 watt unit (because I like headroom as well).
