During a power cut
The Core i9-12900KS's maximum turbo power is 241 W. At 220 V, through a power supply with the lowest 80 PLUS badge[3], that comes to 294 W from the wall: 1.49 A on top of what the rest of the computer draws. From a 12 V battery through an inverter, it takes 28.9 A.
Not counted here: the rest of the computer (motherboard, RAM, storage, fans) and the screen, which have no official figure. Add what you know of them under "Other devices".
