To size for a specific configuration, you can use the IBM Power Configurator that
is available at this website:

The following show the number of nodes that can be operated with no
performance compromise within the chassis depending on the power policy
required. The tables are as follows:
1300 W power supplies:
– 200-240V AC input, no GPU Trays: Table 3-2
– 200-240V AC input, GPU Trays with 130 W GPUs: Table 3-3 on page 32
– 200-240V AC input, GPU Trays with 225 W GPUs: Table 3-4 on page 33
– 200-240V AC input, GPU Trays with 235 W GPUs: Table 3-5 on page 34
– 200-240V AC input, GPU Trays with 300 W GPUs: Table 3-6 on page 35
900 W power supplies:
– 200-240V AC input, no GPU Trays: Table 3-7 on page 36
– 100-127V AC input, no GPU Trays: Table 3-8 on page 37
Power Configurator: Use the IBM Power Configurator to determine an
accurate power model for your configuration.
