Intel Desktop Board D845GLVA Technical Product Specification

2.11 Electrical Considerations

2.11.1 Power Consumption

Table 37 lists voltage and current measurements for a computer that contains the Desktop Board
D845GLVA and the following:
•
2.0 GHz Intel Pentium 4 processor with a 512 KB cache
•
512 MB SDRAM
•
3.5-inch diskette drive
•
15.3 GB IDE hard disk drive
•
40X IDE 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 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.

2.11.2 Add-in Board Considerations

The Desktop Board D845GLVA is designed to provide 2 A (average) of +5 V current for each add-
in board. For a fully loaded Desktop Board D845GLVA (all three expansion slots filled), the total
+5 V current draw must not exceed 6 A.
