1.16 Power Consumption
Table 26 lists the voltage and current specifications for a hypothetical computer configured with
the AP440FX motherboard and the following components: a 200 MHz Pentium Pro processor w/
256 KB Cache, 16 MB EDO DRAM, 3.5-inch floppy drive, 1.6 GB IDE hard drive, and 4X IDE
CD-ROM. The power supply is a 200 watt LPX power supply with at least 65% efficiency. This
information is preliminary and is provided only as a guide for calculating approximate total power
usage with additional resources added.
