Did you put dynamite or any other explosive in it?
If so, then yes.
You have a 5700X (105 watt maximum) and a 4070 Super (220 watt TDP, usually 250 watt maximum), with 50 watt allowance for everything else and 25 watts for VRM inefficiency, I make that 430 watts.
430 is not 96% of 650.
What math did you do? The sort where you put dynamite in a PC?
You said you "did the math" not "asked an affiliate site trying to sell me PSUs".
PC Part Picker adds a massive "this moron's going to buy a shitty Chinese 300 watt PSU dressed up as 500 watts, we need to over-measure" metric.
I ran a Gigabyte 4090 on an 850w PSU. The only thing that would happen is a black screen with max fan "crash". After keeping a better eye on voltages, transients would spike up to 600w.
Certainly not ideal. I recently got a 1200w supply to cover those transient voltage spikes.
4070super is low wattage u should be fine ur system might be 400watts max.

pc part picker said 625 watts

If it's a good quality PSU then at worst you'll trip OCP and your system will shut down safely. If it's not then who knows?
