The RTX 4070 is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply

The RTX 4070 measured 201 W average while gaming (235 W highest 20 ms spike, TechPowerUp). With the Core Ultra 7 265K at its maximum turbo power of 250 W and about 75 W for the rest of the system, the sustained load is about 526 W. A 750 W unit is the safe choice.
