GPU consumes electricity when idle?

Hey guys,

Does the GPU, when idle pump electricity from wall or only when active (playing games for example)?

Also, when active, does it take more from plug the harder it works or it always takes the same amount of energy?

Thanks!

Yes they still use a small amount of power at idle, its much less than when under load though.

Heres a good example of the amount of power different types of cards use under different loads.

It draws power on both occasions(idle and load) but the degree of power drawn vastly varies between the two. If the GPU is pulling the same amount of power in idle as does when in load, then the drivers are either not installed or they're corrupt.

The GPU will only pull power from the PSU as is needed but it has a ceiling as to how much it can draw. Also, the power you see used is by the entire system, not just the GPU.

Got it. Is it possible to make card work harder for crypto mining? Mine seems to be utilizing only 4% of its capabilities when mining. That doesn't seem right to me. When gaming it utilizes almost 100%

No personal experience with mining. Assuming youre mining Ether I found a quick reference on Reddit saying that sometimes GPU usage doesnt appear in task manager with some mining software even though its working. Did you check in any 3rd party monitoring software like GPUZ or HWINFO?
Great answer. I am indeed mining ether, and checking on task manager, that must be why.
