2.11 Electrical Considerations
2.11.1 Power Consumption
Table 42 lists voltage and current measurements for a computer that contains the Desktop Board
D845GEBV2/D845GERG2 and the following:
• 2.80 GHz Intel Pentium 4 processor with a 512 KB cache
• 64 MB AGP add-in card
• 256 MB DDR 333 SDRAM
• 3.5-inch diskette drive
• 10 GB IDE hard disk drive
• 6.2 X IDE CD-ROM/32 X CD-ROM drive
This information is provided only as a guide for calculating approximate power usage with
additional resources added.
Values for the Windows XP desktop mode are measured at 640 x 480 x 256 colors and 60 Hz
refresh rate. AC watts are measured with the computer is connected to a typical 300 W power
supply, at nominal input voltage and frequency, with a true RMS wattmeter at the line input.

NOTE
Actual system power consumption depends upon system configuration. The power supply should
comply with the recommendations found in the ATX/ATX12V Power Supply Design Guide,
Version 1.1 (see Section 1.5 on page 20 for specification information).

2.11.2 Add-in Board Considerations
The Desktop Boards D845GEBV2 and D845GERG2 are designed to provide 2 A (average) of
+5 V current for each add-in board. The total +5 V current draw for add-in boards is as follows:
• For a fully loaded Desktop Board D845GEBV2 (all seven expansion slots filled), the total
+5 V current draw must not exceed 14 A.
• For a fully loaded Desktop Board D845GERG2 (all four expansion slots filled), the total +5 V
current draw must not exceed 8 A.
