Power consumption 11.1.2 Bulk Power assembly (BPA) Note:  Consider the following points: The utility power consumption for the z15 for PDU option is listed in Table 11-4. The Bulk Power Assembly consists of the following features: Considerations:  Power consumption is lower in a normal ambient temperature room, and  for configurations that feature a lesser number of I/O slots, smaller amount of memory, and  fewer PUs.  Power estimation for any configuration, power source, and room condition can be obtained  by using the power estimation tool that is available at the IBM Resource Link website (login  required). On the Resource Link page, click  Tools Power and weight estimation . GLYPH<SM590000> The power values that are listed in this table assume the CPC process drawer and PCIe+ I/O drawers are plugged  to the maximum with highest power features (that is, memory and I/O adapters and fanouts). Also assumed is that  maximum ambient temperature is used. GLYPH<SM590000> Typical configurations and data center conditions result in lower power. A calculator available on Resource Link  calculates power and weight for specific configurations and environmental conditions.
