Disable SLI = Save Power?

[Wayne Tai]

I upgraded to 2 Asus GTX 1080 ROG Strix recently and I run them on SLI. 

 

Since i have a 1440p 60 fps monitor, it's overkill for most of the games I'm playing - I'm planning to upgrade to the Asus PG279Q with 1440p and 165 Hz refresh rate but that won't happen until august. 

 

If I am playing less demanding games, will it do any good to disable SLI for now? 

 

Another to ask the question is:

If I have 1 GPU at 100% load vs 2 GPUs at 50% load .. which one consumes more power? I usually cap my frame rates at 60 anyway.

no difference in power saving for SLI, if you want to save power start using your onboard IGP if you have one and use a software to copy the framebuffer (like nvidia optimus) or just plug the monitor into the 1080 when gaming.

could always enable 4k supersampling haha. Disabling SLI doesnt turn off one of the cards, just disables using them in tandem in games afaik. If you want to save power, unplug one

But if I only have 1 monitor and I turn off SLI, the 2nd GPU will be in idle no?

 

I don't want pull out the cards because the RGB effect lok great on my set-up
