GPU Server Power Consumption: Estimating Electricity Bills for AI Clouds

Running high-performance GPU nodes 24 hours a day requires significant power grid capacity and thermal cooling.

Here is how power consumption translates into monthly utility expenses.

Average GPU Power Ratings

1. 1NVIDIA H100 SXM: 700 Watts per GPU.

1. 2NVIDIA A100: 400 Watts per GPU.

1. 3NVIDIA RTX 4090: 450 Watts per GPU.

Monthly Utility Cost Calculation

A 4-card H100 server draws 2,800 Watts continuous power. At $0.14 per kWh:

Daily kWh = (2,800 W x 24 hrs) / 1000 = 67.2 kWh / day. Monthly Power Bill = 67.2 kWh x $0.14 x 30 days = $282.24 per server node.
