Power Consumption
Tables 3 and 4 list the measured current and voltage requirements for the Advanced/RH motherboard configured with 16 MB of DRAM. Table 5 lists the typical power consumed by the same configuration.. This information is preliminary and is provided only as a guide for calculating approximate total system power usage with additional resources added.
