Power of white noise set in Simulink

good morning to all of you,

I should build a kalman filter with simulink and I have to put a white noise in the output. some of you would be able to tell me what relationship between the power noise of the ' band limited white noise block' and the variance of the noise I choose. For example, if the variance of white noise is 3, how much should I set the power noise?
