Yes. Take the value in watts of each power supply. Divide watts by volts to get amps. Then just add up the amps.
Example: I have a rack of 12 servers. Each server has 2 770w power supplies. My voltage is 208vac. 770w / 208 vac = 3.7 amps. So each power supply can draw a MAX of 3.7 amps. 3.7 A * 24 = 88 amps MAX if each power supply were drawing full current. BUT - two power supplies presumes load sharing. So each power supply is only drawing half-current. Thus, the MAX consumption can be 44 (12 * 3.7) amps at 208 vac for the full rack.
