When designing my cabinets I used a spreadsheet that let me try out 
different configurations of modules so that I could estimate the 
power draw and the number of power supply connectors required. I used 
the published power draw spec for each module, if available. 
Otherwise, I used an average value of all the other modules. This let 
me take into account the more power hungry modules like the Time 
Machine and UEG. In the end I came up with results that were fairly 
close to "Schreiber's law".
