Intel Desktop Board D845GEBV2/D845GERG2 Technical Product Specification

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.
