For 3 phase power, multiply by square root of 3. (Well, and the power factor, but let's assume 1 for a second).
480 x 210 x 1.732 = 174 kW
Adding in a power factor of 70% (shouldn't be nearly that low, but it's not 1 either since it's a AC to DC transformer) you'll get:
480 x 210 x 1.732 x 0.7 = 122 kW
Thanks deonb/RandyS. My 3-phase knowledge is rusty...my electrical engineering class was only 13 years ago!
