Puzzled how you get 3400 miners.  

Assuming an 80% average electrical load just for miners you have 4 Megawatts to play with.  This ignores power for fans, cooling etc.

This means your average power consumption per unit is 4000000/3400 = 1176 watts.  But miners such as the S9 draw more than this.

Just how do you get 3,400 miners?
