I'm currently in the process of upgrading my pc. I want to demanding games like ARK Ascended and Cyberpunk 2.0. I currently have a 9700k and 2080 Super which is fine but not great anymore.
I'm thinking of getting the 7900 XTX and a AMD 7800X3D. Because upgrading all at once is kinda expensive I think I want to buy the 7900 XTX now, and upgrade my mainboard and CPU in a month or two. My current PSU has 650 Watts and I would like to know, if I have to upgrade this for the 7900 XTX. I will definitly upgrade once I have the new CPU (and memory) but it would be nice if the 7900 XTX would run with my 650W PSU. I tried some PSU Calculator Websites but every website gave me a different number which is why I then used PC Part Picker which told me I need ~560 Watts. Does this mean my PSU is powerful enough? I heard that during peak performance GPUs draw more power than the TDP.
Looking forward to helpful anwers
