<<< TLDR: GTX 1650 idle power consumption is sitting at 32W instead of something like 8W. That's 4x what it should be... How can I fix it? >>>

Hello all. I'm working on a low power 12V SFF everything emulator to be used while traveling the US in a teardrop camper. I've had it running for about a week now and and since this will be run off the camper's battery, I've been taking my time undervolting/underclocking to lower power consumption. While doing this I noticed that my idle power consumption on the GPU is sitting at 32W according to HWinfo. GPU usage is sitting at about 0-1% and the clock is sitting at 300MHz in Afterburner.

I know 33W doesn't seem like much, but according to reviews it should be closer to 8W. That means my card is using 400% more power at idle than it should be.

PC specs:
Windows 10 Home Edition
Silverstone Grandia gd09 (Custom_Mod SLM1 4L isn't here yet)
Gigabyte B550I Aorus Pro AX
Ryzen 5700X (CO-30 all cores and PPT 45)
Noctua NH-L9a chromax
Zotac GTX 1650 OC GDDR6 (1755MHz @825mV +500 memory clock)
Crucial P3 Plus 4TB Gen4 NVMe m.2
OLOy 2x8GB DDR4 4000MHz CL18 1.4V
RGEEK DC ATX PSU
12V 240W AC/DC power brick
Currently hooked up to an Epson projector set to 1080p @ 60Hz (I've read that UHD and high refresh rates can trigger high idle power)

What I've tried:
Resetting GPU to factory clocks/voltages
Clean reinstall of graphics drivers
Nvidia Control Panel -> Power Management -> Optimal Power
Power Options -> Advanced Settings -> PCI Express -> Link State Power Management -> Maximum Power Savings
BIOS -> ASPM set to L1 (didn't help so returned to the default "disabled")

It's crazy that it's using so much on idle when the GPU only uses 60W while running Superposition. It's not hot either, it idles around 30C and only gets to 57C under full load.


Any ideas? I really appreciate any help or suggestions. The GPU is brand new so I guess if I can't get it figured out, I can always talk with Zotac or NVIDIA, but that'll be a pain in the rear.

Are you able to put the PC on something like a kill-a-watt to double check the software reading is accurate?

Yes, I forgot to mention I have it plugged into a kill-a-watt, but it's only able to tell me the whole system power draw. I imagine the sensors are reading correctly though since the full system draw at idle hovers around 60W +/- 2W. TPU shows the AUROS AX at 9W idle, I imagine the ram uses 6W max, the power brick uses 1-2W even when the system is off. So that's 9+6+2=17W. So at idle, 60-17=43W being used between the CPU and GPU and neither of them are really being utilized. If HWinfo is right about the GPU using 32W, that means the CPU is idling somewhere around 11W which seems about right, given the undervolting. This leads me to think HWinfo is showing accurate numbers.

If you want power savings, run it off the iGPU and remove the video card. That will save you the most power. You can also try downclocking the card as much as possible. Lower the core and memory to as low as it will go and the power limit as low as that will go too. Go to windows power options and under PCIe link state, chose maximum power savings. That is about the best you can do if you want to keep using the card. Just FYI, my computer uses around 175W at idle and that is with a 11700k @ 5 Ghz and a 3090Ti also overclocked.

I appreciate you attempting to help but what you've suggested doesn't apply to the issue I'm having. The problem I've got isn't concerning total system power; I've already done some work on that front. It only draws 121W under FULL load. What I'm dealing with now is the fact that my GPU is drawing significantly (400%) more power during idle conditions than it should if it were functioning normally.

As for your suggestions...
I have a 5700X, which means no iGPU and I wouldn't want to use one anyway because this system was built with the GTX 1650 in mind.
I've already undervolted and slightly undercooked both the CPU and GPU as far as I can without significantly sacrificing performance.
As mentioned above, I've already tried setting Link State Power Management to Power Savings.


If you have any suggestions, that I haven't tried, to help resolve the idle power draw issue, I'd love the input.

Does GPUZ show the link state downclocking when the card is idle? Is the GPU frequency and memory frequency downclocking in Afterburner (or OC program of your choice) when idle? Usually high idle power in a GPU is caused by the card failing to downclock or the PCIE link state failing to downclock. If they are all downclocking appropriately, then I am not sure you can really save any more power. I dont know what the 1650 should be downclocking to, but with my 3090Ti, at idle it downclocks to 210 Mhz.

According to GPU-Z link state is working properly. It shows PCIe x16 3.0 running at PCIe x16 1.1 at idle.

As for the clock speeds at idle, it seems like none of the software can agree with each other. They all show 300MHz GPU clock, but different memory clocks.
GPU-Z: 100
HWinfo: 540
Afterburner: 405

Oh I also had the idea to pull the GPU and start the computer while plugged into the kill-a-watt. Of course I'll get no display, but it gives me an idea of how much power the GPU alone is using, without relying on software. 60W with the GPU installed and 38W with it removed. So it looks like it's only drawing 22W instead of the 32W HWinfo shows. Although, oddly GPU-Z also shows 32W. If it is actually 22W, that's much better, but it's still 275% of what everyone else seems to be getting.

It's crazy that your (450W) 3090ti down clocks lower than my puny little (75W) 1650.

Well I still don't know what's going on with the GPU. I've managed to get the full system power draw down to 46W at idle by adjusting some BIOS settings and pulling some SoC voltage. This still seems kinda high, but a lot better. Although there doesn't seem to be a ton of data out there about what the normal idle consumption of a 5700X is. GPU-z and HWinfo still show the 1650 idling at 32W, which at this point doesn't seem as likely but it could still be using far more than 8W.

Any suggestions on how to use the kill-a-watt to give a better understanding of what's drawing so much power at idle? Maybe it's not the GPU, but I can't know until I can figure out a good method to test the systems power consumption.

I don't have the same card as you, but a similar one -- I've actually got link state power management off.

How did you uninstall / reinstall drivers -- did you boot to safe mode after uninstalling, and run Display Driver Uninstaller to fully clean the old ones out? That's part of the driver update process here.

I will check my BIOS settings; this is an older MSI motherboard (Z270), but I doubt that I made any changes to the default settings with respect to graphics, apart from disabling the iGPU perhaps.

I have seen instances in the past of certain Nvidia driver versions that did not handle power management correctly, but this would have been back in the Maxwell generation; have not seen it recently. That might be the other thing I might suggest, just trying a different version than the one exhibiting problems, if you haven't already.

Thanks for responding! I didn't boot to safe mode to uninstall/reinstall the drivers. I simply launched the driver installer and selected the "clean install" option. I just went ahead and uninstalled/reinstalled again, this time using your recommendation. Sadly it doesn't appear to have made any difference. Today I noticed, while looking in the Device Manager that my GPU's power state shows D0 (fully on) all of the time. So it seems like even if it is in fact properly downclocking during idle, it never actually changes to the power saving state. I wonder if this could be the problem? Would you mind doing me a favor and checking yours to see if it also shows D0 at idle?

Thanks for that. Darn, looks like yours is also showing D0. So maybe I've misunderstood the GPU power states. I've running out of ideas on the software side of things. I guess it's time to call it quits and address it as a hardware issue. I'm still within Amazon's return window, so I've gone ahead and set up an exchange for a new card. ETA is the 23rd for the new card to arrive, I'll be sure to update this thread after the swap.

Edit: Recording power consumption, so I don't forget by the time the new GPU arrives. After undervolting RAM and lowering SoC a bit more I'm sitting at 42W idle and 113W max, measured at the wall.

Ok. It turns out the GPU isn't the problem. The replacement GPU came in yesterday and I swapped it out. The new GPU reads 32W at idle, in both GPU-Z and HWinfo. I guess all of the software is reporting wrong. The total system power is still measuring exactly the same at the wall. So it looks like I've got this computer dialed in about as well as I can. It just really sucks that I can't seem to get it to report correctly. I'd really like to see what my GPU is actually using, in real time.

On the bright side, the silicone quality is ever so slightly better on this new GPU. I was able to get an extra 20MHz at the same voltage when I undervolted this one.

Thank you to everyone who tried helping me with this issue that turned out to be nothing. At least through this process I learned a few things and it drove me to chase lowered power consumption in other ways. Chasing this "problem" ended up saving me an extra 18W from where I started at the beginning of this thread.
