Total System Power Consumption 
The following tables contain minimum and maximum power consumption for the 1.1 GHz and 1.5 GHz 
Eserver pSeries 670. Minimum power consumption is based on a configuration consisting of a single 4 
GB memory card, 1 PCI card per I/O subsystem, and 1 DASD device per I/O subsystem. 
Maximum power consumption is based on a configurations consisting of a two 32 GB memory cards per 
MCM module in 1.1 GHz machines and two 64 GB memory cards per MCM module in 1.5 GHz machines, 
maximum PCI cards (20 per I/O drawer), and maximum DASD (16 per I/O drawer). 
Power consumption calculations are estimates. Actual values may vary. 
Calculate heat load (Btu per hour) by multiplying the power (in watts) for the configuration by a factor of 
3.4. 
Note:   Certain system configurations only support a maximum number of I/O drawers. If a system does not 
support a particular count of I/O drawers, it is indicated with ″N/A″.
