Power consumption/voltage peaks
The displayed power consumption in the tools is NOT! The complete on-board power, that is what the card sucks out of the can. As a guideline, you can add roughly 35 to 40 watts for an RX 6800 and about 45 watts for an XT. This always varies a little bit, depending on the card. But since almost all models use only the high quality powerstages from Infineon (apparently a specification from AMD) you get a consistently high quality on the customs. Positive are of course more phases for overclocking, the cards seem to scale cleanly with the phase placement.
The Red Devil, for example, currently carries most of the phases on the board. Otherwise the cards behave inconspicuously with the power consumption, I couldn’t notice big fluctuations, but of course I have only limited equipment. But the cards are a power supply killer only with very high overclocking, especially the RX 6800 is tame and can be used with small power supplies around 450Watts without any problems, as long as the quality is right!
Even an RX 6800 XT with the standard ASIC of the reference of 255 watts draws only about 400 watts in the whole system, even with my quite decent system, and the card is already overclocked. Apart from that, when it comes to voltages and power consumption, you are already at the best address here at Igor, not only in Germany but worldwide. In all the reviews you will find everything you need to know about it.
