Non-gaming power consumption seems to have increased a little bit, probably due to the switch to GDDR6. While the differences might look relatively big (bar length), it is minimal in absolute terms. Just 2 W higher, it won't have any significant effect on heat, or your power bill. Media playback power consumption is one of the lowest, just 8 W, which will be important for an SFF media player as you would want to avoid heat as much as possible.
Since the card has no additional power inputs, it must be limited to 75 W or it would overload the PCIe slot power delivery circuit. Thus, the board power limit is set to 75 W, and the card pretty much follows it. We did measure some spikes above 75 W, but only for very brief moments and not that far above 75 W, so everything is fine.
Recommended PSU: 300 W
