RX 7900 XTX power consumption

Updating your power supply may be necessary if your graphics card is among the most recent generations of flagship models, such as the AMD Radeon RX 7900 XTX.

The best course of action is to determine whether your current PSU can handle the enhancements offered by AMD’s new line of GPUs if you want to ensure everything runs smoothly and steadily.

The RX 7900 XTX is one of the cards in the range, despite there being a number of them. AMD places a high emphasis on performance per watt. Therefore RDNA 3 offers a lot of power for a relatively modest amount of processing power.

Even then, a reliable PSU is necessary to make sure everything functions properly. The card’s TBP has been set to 355 watts, which is around 100W less than the RTX 4090 from Nvidia.

RX 7900 XTX specs

AMD gives a suggestion for a minimum power supply specification of 800 W. So it’s not too high out of the ordinary and so you might not need to upgrade it necessarily.
