Going have a buckpuck 700ma 24v, 2 24v 100ma fans for a total of 900ma would a 1amp 24v power supply be good? If yes would it be good with a pwm for the 2 fans? What im worried about is startup power surge, if the peak maybe to high at the start. I may also just use one fan 100ma and the 700ma driver, a 1amp would be plenty for that?

 

Generally yes, a 24v 1A supply should be efficient for 24v 900mA (0.9A).
