KFA2 GeForce RTX 2080 Ti OC in test – a whopping 380 Watt Power Limit with RGB planking

Power consumption and loads

The power consumption of this board partner card is in some cases significantly higher than that of the Founders Edition. In gaming and the Torture Loop, you can see that Galax has raised the Power Target significantly. I measure a plentiful 311 watts in gaming and torture loop, which is about 11 watts more than was deposited in the BIOS as a typical Power Target. If I overclock the card to its limit, it is a good 378 watts, which is almost what was set in the BIOS for this card as the maximum power limit.

The spikes are still acceptable during normal operation and are also below what a GeForce GTX 1080 Ti OC produces. But in extreme cases with maximum overclocking, these peaks can also speed up to almost 500 watts. And that's exactly what's going to be really borderline! I certainly don't have to stress that the card then acts at the limit.

The voltages are in the expected range, with the oc's permissible board power being the limiting factor, not the voltage. One notices very clearly that Nvidia deliberately limits here before a possible maximum is reached. However, one can also see from the drop of the curves that the temperature factor plays a major role in heating.

The load distribution on the rails is still quite good in normal operation, because the maximum 5.5 amperes of the motherboard slot are never exceeded. But with maximum overclocking, the card with its abundant 6 amps is almost 11% above what the PCI SIG has set as the top limit for the motherboard slot!

This is neither nice nor useful, even if it only works if you really beat out the full 380 watts from the circuit layout. Then the balancing is lost a little bit. The average is not even the worst part, because the peaks go up to 8.5 amperes. Since I criticized AMD at the time, I have to do this with Nvidia's reference layout now, because standard remains standard, otherwise you could do without it altogether.

Of course, this shift is also slightly relative, if one assumes that (a) with better cooling then only approx. 350 watts must be supplied through the supply lines in order to be well with the front and then at approx. 5.5 Ampere lands and (b) no one will seriously operate this card with this setup. But you could stop it and that's what you have to criticise.

 

Detailed recording of power consumption and flowing currents

As usual, I now also set aside the power consumption and the flowing currents as detailed graphics of my oscillograph measurements. A service that hardly anyone else offers and which shows how the maps "tick" in detail:
