I compiled the power consumption results by testing each card under idle and full stress when the card was running games. Each graphics card manufacturer sets a default TDP for the card which can vary from vendor to vendor depending on the extra clocks or board features they plugin on their custom cards. Default TDP for the GeForce RTX 4090 Founders Edition is rated at 450W and the peak power limit is rated at 600W.
