Non-gaming power consumption is increased a bit over the AMD reference design. With 6–7 W more, it's not as dramatic as it looks in these charts. Like on all other Navi cards, multi-monitor power consumption is still too high when compared to competing NVIDIA cards.
Gaming power consumption is increased by around 50 W over the AMD reference design. Since the card is overclocked out of the box with a higher power limit, some of that increase is justified. Still, performance doesn't scale 1:1 with power, so some efficiency is lost.
Recommended PSU: 600 W
