Power draw on SLI-enabled config vs non-SLI?

[Kiol]

I've always read suggestions about recommended wattages for two of the same graphics card in a build regarding them to be in SLI, which is the usual case, but rarely have I seen suggestions not mention the cards being in SLI. For reasons like 3D rendering where SLI can't be used, but multiple graphics cards can still be utilized, a non-SLI configuration would be used. What I'm wondering is, does enabling and using the SLI configuration cause the graphics cards to draw more power(watts) versus a non-SLI configuration? I've never seen it measured before and it would make sense that they would draw the same amount of power in either scenario, but I still want to know if any tests or comparisons exist.

Would still take the same amount of power. 

 

I think the term "SLI" is so ingrained at this point that we'll (the community) use it for anything that involves two GPU's even when it's erroneous to do so.

[Enderman]

No it would be exactly the same.

Wouldn't make any difference, they would use the same (Unless you mean in games, then one card simply wouldn't be utilised). 

[pommedeterror007]

Depending on the load percentages it should still be the same. SLI is usually meant for graphical stuff (Games ETC) rather than processing I believe (correct me if im wrong).

If anything they will use More power not in sli because they will be used 100% by a good program unlike games which only. Use a % of the second gpu

Well the cards run st 100% in games so if another program can do that the power draw would be the same. The rest would be based off CPU draw which varies just as much.
