Here, in Madrid, most of my friends are running 10 to 20 amps. I'm an outlier, running 25amps (5.75 kW) because all my stuff is electric (water heater, cold/hot air conditioning, microwave, glass-ceramic stove...).
My Ryzen 5 desktop is consuming 0.3 to 0.5amps (being 50 to 120watts at 220V), supposing you're using 110volts your desktop computer must be a big gaming rig if it's consuming 350 to 550watts ;)
