Press the button and your browser reads the name of your computer's graphics card: we tell you whether it is this one, and compare the two if it isn't.
The card's name is never sent to our site: it stays in this browser alone until you press "Forget my device".

During a power cut
The GeForce RTX 4090's rated board power is 450 W. At 220 V, through a power supply with the lowest 80 PLUS badge[3], that comes to 549 W from the wall: 2.78 A on top of what the rest of the computer draws. From a 12 V battery through an inverter, it takes 53.9 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".
