Power supply for 1080Ti

[Andythe Random]

I notice the 1080Tis show suggested power supply as 600W, but the OCUK configerators allow you to pair one with a 500W PSU.
Would this be enough?
Would 550W be enough?
Or do they really need the recomended rating supply?

That's what I thought, thanks for confirming it for me.
