Table 49 lists voltage and current measurements for a computer that contains the Desktop Board
D845EBG2/D845EPT2 and the following:

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 1024 x 768 and 75 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 18 for specification information).
Table 49.
Note:
The Desktop Boards D845EBG2 and D845EPT2 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:
•

ACPI S0
ACPI S1
ACPI S3
ACPI S5
2.4 GHz Intel Pentium 4 processor with a 512 KB cache
64 MB AGP card
512 MB DDR SDRAM PC266
3.5-inch diskette drive
20 GB IDE hard disk drive
6 X IDE DVD-ROM/32 X CD-ROM drive
For a fully loaded Desktop Board D845EBG2 (all seven expansion slots filled), the total +5 V
current draw must not exceed 14 A.
For a fully loaded Desktop Board D845EPT2 (all four expansion slots filled), the total +5 V
current draw must not exceed 8 A.
The system running a graphics-intensive benchmark when the measurements in the ACPI S0 row were taken.
