980 ti power percentage at %45 no matter what

[Guest]

He title explains it, my GPU usage is low but my power % is at a minimum of %45. It is causing my GPU to be at 55c at idle.

Hi,

When you have that kind of problem, we need more info to be able to help you.
What's the rest of your rig, what games you play when the problem happens.

Temperature will vary based upon the model chosen. Some models won't have the fans even turn on until the temps reach 65C. You can change that by modifying the fan curves with a tool like Afterburner. As for power used, that's not going to change much unless you put a significant load on it.

Download Furmark and run it for 20-30 minutes. In the upper left you will see temps, power and other important parameters and you shoulld equal or exceed 100%. If temps break 85C, the card will throttle itself.

The only other relevant component is the PSU. If you want to check one aspect of that (voltage stability), you can run HWiNF) while Furmark is running. Look at the voltages on the 3.3, 5 and 12 volt rails and see how they vary (look at min and max columns).... the ATX standard is 5% .... a gaming / enthusiast box should have less than 2.5% and if looking for max overclocks, you'll want less than 1%.

To see if you make it, do this:

A user here on the forum reported that his 12v rail had an 11.35v in the "minimum" column of the 12 v rail of a CX750.

12.00 - 11.35 = 0.65
0.65 / 12.00 = 0.054 = 5.4% which was outside the ATX standard.

Guys, my card is the EVGA SC ACX+ 980 ti, I have adequet air flow, and my PSU is EVGA 1000G2. It is that when I am idle my power % is 45, and because of that it is at a higher temperature (55c). It is also at 1100mhz all the time too.

Well knowing the card and PSU is beneficial but minimally so. The SC series typically uses a reference PCB which has some limitations but they shouldn't affect the issue here. The G2's fan can be annoying in an otherwise quiet rig but it delivers stable power with low noise.

However can't comment on what of anything is wrong until you run Furmark. Telling us where it is "all the time" isn't really useful as we have no idea what the PC is doing "all the time". That is why running a utility which puts a known load on your GPU(s) is essential for ruling out other types of problems.

EVGA Precision has a feature called K-Boost which allows the GPU's clock speeds and GPU voltage to run at their highest set frequencies all of the time. It disables all of the power saving features that current video cards use to aid with lower temperatures and lower power consumption. I find it useless but note it just so you are aware that power saving can be disabled.

Let's get the Furmark test done and then we can move on from there.

I test in 3D applications, it goes up to %95 power usage in valley benchmark. During idle it is not fully down clocking, I think that i did enabled Kboost, I will try to disable it or maybe turn it on and off.

Like the core MHz is at 1100, memory 3500, temp(fans at 700rpm) ~55, and power usage at %45 at idle. It does rise during gaming, but at idle it doesn't fully down clock.
