An administrator has 120V, 150-amp service in the datacenter. Which of the following is the MAXIMUM number of servers with a faceplate rating of 65W that can be racked in the datacenter?

200 servers consume only 13,000W, significantly underutilizing the available 18,000W capacity and not representing the maximum.

225 servers consume 14,625W, which is within capacity but is not the maximum number of servers the circuit can support.

250 servers consume 16,250W, still within capacity but not the maximum achievable count given the available power.

Total power is calculated as voltage multiplied by amperage: 120V x 150A = 18,000 watts. Dividing by the 65W faceplate rating gives 18,000 / 65 = 276.9, which floors to 276 whole servers. Since 276 is not an available choice, 275 is the highest answer that stays within the 18,000W limit without overloading the circuit.

300 servers would require 19,500W, which exceeds the 18,000W total available and would overload and trip the 150-amp service.
