Should this Power Supply be adequate for the build?

I currently have the system as configured with the seasonic PSU installed, but am waiting for a GPU. I found a decent price for a used 1080 ti and was wondering if a 550 watt power supply was enough? The official NVIDIA spec seems to recommend a 600 W power supply is why I'm asking.

Pulled the PSU spec information from a listing. The important section is the 12v rail which will deliver up to 540w. I would say that this PSU should be capable of running the 1080ti just fine. The 1080ti is rated to up to 250w of power draw, factoring that in the 11500 is a 65w processor that might boost higher (likely to 85w)

 

Total power draw while gaming will probably be around 450w on this system which is well within the safe limits on the PSU.
