    Hi!
    Try to use this formula:
    P = U x I
    U = P / I
    I = P / U

    P = WATT
    U = VOLTAGE
    I = CURRENT

    In your case this should be like this:
    I = 200/42
    I = 8.33A
    8.33 x 3 = 25A

    Thats right, you will need 8.33Amps to run each motor at 200W. 20Amps MIGHT be enough if you don't run ALL 3 motors at the same time. Even running 2 of them will push the 20A limit because DC motors need more current to get up to speed, so peak currents might be well above the rated 8.3A.

    Just get 2 car batteries and make it easy. Then you won't even need a 20A supply, 5A will be plenty.
