I understand why your website shows it was having 3 pcie power connectors as the Powercolor website does too... but they are using the same photo for the XT as they are the XTX. It is lazy of them, and wrong
On the same site they show this which clearly indicates any power coming down 3rd connector would be going nowhere

Main reason I know its wrong is I have the card
Looks like 2 to me.
You originally had it right - https://www.techpowerup.com/gpu-specs/powercolor-red-devil-rx-7900-xt.b9946
I went through figuring it out 2 weeks ago, I have just been distracted since then to come back and look again.
A general lack of reviews of the card probably doesn't help.
