Ratings
Operating an S875WP1-E
baseboard
at conditions, beyond those shown in the following table,
may cause permanent damage to the system. The table is provided for stress testing purposes
only. Exposure to absolute maximum rating conditions for extended periods may affect system
reliability.

“Coppermine-T or Tualatin” maximum case temperature.
2. VDD means supply voltage for the device.
9.2 S875WP1-E Power Budget
The following table shows the power consumed on each supply line for a Intel Server Board
S875WP1-E that is configured with one Intel Pentium 4 processor (pulling max current), all
PCI slots full and pulling max amount of current, memory completely full, AGP card installed,
4 SATA drives on Promise PDC20319 controller actively running, 2 SATA drives hooked up
to ICH5-R controller, USB pulling max current, and fans assuming max current draw X 5.
The numbers provided in the table should be used for reference purposes only. Different
hardware configurations will produce different numbers. The numbers in the table reflect a
common usage model operating at higher-than-average stress levels.
