Power consumption at different loads
The power consumption in the gaming loop is at the measured approx. 234 watts in the BIOS #1 not as much above what the reference model still has with approx. measured 223 watts in the default BIOS. This means that the reference card came in at just under 260 watts.
We have given ourselves the saving mode here, because the card loses performance unnecessarily. The BIOS #2 is rather unnecessary from a player's point of view. If so, then take the BIOS with the higher nominal clock and try the sub-voltage if necessary. This is extremely chip-dependent, but could be more worthwhile than the BIOS #2.
The corresponding voltages for both loops in the factory state are shown in the following diagram:
Compliance with the standard on the motherboard slot
With a maximum of 1.8 amps (torture), the card is well below half of what the PCI SIG sets with a maximum of 5.5 amps (66 watts) for the 12 volt rail on the motherboard slot. In the Gaming Loop, with only 1.4 amperes, one is much further below overall, the balancing has been implemented very exemplary and the motherboard lot is hardly seriously burdened.
Detailed graphics: power consumption and currents
For better illustration, we have also recorded all measurement results as detailed curves in the graphs below. In the Idle, of course, things are still quite moderate:
The currents are also rather minimal.
Naturally, the power consumption peaks in gaming are the most important. With peaks of up to 327 watts, however, you can live well, because they occur only very briefly.
The flowing currents behave in an equivalent way:
In the stress test, the short-term peaks are significantly lower, even if the power consumption is again slightly higher than for gaming.
Even now, the flowing currents follow the curve and show no abnormalities.
