Tables 32 and 33 list voltage and current specifications for a computer that contains the
motherboard, a 200 MHz Pentium processor with MMX technology, 32 MB SDRAM, 256 KB
cache, 2 MB SGRAM graphics memory, a 3.5-inch floppy drive, a 1.6 GB hard drive, an 8X IDE
CD-ROM, and a 28.8 Kbps ISA faxmodem. This information is preliminary and is provided only
as a guide for calculating approximate power usage with additional resources added.
NOTE
AC power measurements include all peripheral components mentioned above. DC current
measurements include only the motherboard components.
