Quick Answer
Yes, 700W is enough for the RTX 4070 Super with any mainstream CPU. The RTX 4070 Super has a 220W TDP, and total system power typically stays under 400W. NVIDIA recommends 650W, so 700W gives you comfortable headroom.
NVIDIA's official recommendation is 650W for the RTX 4070 Super. At 700W, you exceed this recommendation with room to spare. The PSU runs at an efficient 50-60% load during gaming.
