I'm currently upgrading my system to include a 1080 Ti but don't know if my current PSU will be powerful enough. I have a 550w PSU, I have put this all into pc part picker (https://pcpartpicker.com/list/VvKGvW) and got an estimated wattage of 465w which sounds like it would be fine but other people say 600w minimum or more often and also would I be able to overclock my CPU with my current PSU, I haven't done this yet and don't know if I will but I'd like to be able to eventually.

Any insight would be great.
Thanks in advanced for any help.

The GTX 1080 ti will suck down 250 watts gaming and your CPU is about 100 watts. A 550W PSU may work but there's not much headroom there including the rest of your parts. A good quality 650 would be optimal but you could try your 550W.
