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. The default TDP for the Radeon RX 7800 XT is rated at 263W while the Phantom Gaming runs around 290W.
