Single-monitor desktop power consumption is very low with only 7 W, which is slightly better than the RTX 2060 and on-par with the GTX 1660 Series. Multi-monitor power consumption is four times as high though, which has been an AMD problem since forever—when multiple monitors are connected, the memory will run at full 3D speed, which drives up power consumption a lot.
Media playback power consumption is more reasonable though, which is important for media PC systems.
As you can see there's huge differences between the old BIOS and the new BIOS. The reasons are not only the increased clocks on the GPU and memory as Sapphire also bumped the GPU voltage from 0.9 V to 1.0 V (to ensure stability at the higher GPU frequency). While the card with the old BIOS was more power efficient than most of NVIDIA's Turing lineup, it now sits right in the middle of the various Turing cards—better than the RTX 2060 and comparable to GTX 1660 Super—pretty impressive for AMD.
With a typical power draw of 150 W and a worst case consumption of 180 W, the RX 5600 XT Pulse is very modest in its power requirements. This ensures upgraders won't have to buy a new power supply.
Recommended PSU: 450 W
