NVIDIA GeForce RTX 3080 Ti FE Review - Almost an RTX 3090, but with half of the memory for gamers | Page 9

Power consumption and compliance with standards

Let’s first look at pure gaming in WQHD as an average across all benchmarks:

However, if you add up the power consumption in Ultra HD, which I measured in all games over the entire runtime, then everything is slightly higher again:

And with DXR? Then it gets a little more economical again.

So there are no big secrets when it comes to power consumption, because what NVIDIA specifies as TBP is even slightly undercut. With just under 14 watts at idle, it’s within the range of many board partner cards from the GeForce RTX 2070 Super to RTX 2080 Ti, albeit relatively high. The partial load ranges are realized relatively sparingly, which could also be due to the better controlled cycle. Thus, the card “only” reaches around 346 watts under real full load in Horizon Zero Dawn and full warming, which is 4 watts less than specified in the specs. You won’t even get close to 350 watts (or even above) in the stress test. The following table now shows the maximum values of the respective load scenarios.

Which brings us to the specifications, because in the end it is clearly regulated by firmware what is possible as well as maximum and minimum against may. A maximum of 400 watts is allowed for the VU, which can also be called up with the appropriate software.

As a service I now offer the high-resolution curves of my measurements, which again prove which load changes a current power supply can be exposed to. We see 2 graphics each for gaming and stress test with the power consumption in watts and the respective currents, which will also play a role in the next chapter.
