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.
