[JakubFindra]

i have optiplex 790 motherboard, 600w 80% plus PSU, 8gb ram, i3 2120 3.3ghz,
two 560Ti's that i want to sli, but in nvidia control panel there is no option for SLI, what should be the problem?

Which form factor of the OptiPlex do you currently have? You're also going to need more than 650W of power if you really can SLI on that rig.

oh, ok thanks, but they are running both good, in the same system, connected with a bridge, but there is no option for SLI in Nvidia control panel, and i have the small one, but in diferrent case, with original power switch.

they both show up, but the otion to maximize 3d performance is missing and there is no option such as SLI, i cant explain more because i am from Slovakia so my english is limited

That motherboard does not support SLI. The 2nd 16x port only runs at 4x, SLI requires both slots to run at atleast 8x.
