Can Power Query handle this much data?

Good morning,   I have one dimension table.  8 fact tables.  Each table has approximately 300,000 records.     Before I create this data model, can power query efficiently join (Left Outter Join)...

    Jkaelinwhat are your data types in your facts? i really dont see an issue in combining them if they are most numerical, why doing you just try and see what happens?  essentially its mostly up to your machine.   and obviously because this is in memory technology you want to make sure you standarize your data as much as possible , the less unique values you have the better in order to get the most compression.  Start only with what you need rather than everything.
